A. Breed Overview: The Maltese and Their General Health Profile
The Maltese is a small toy breed known for its long, silky white coat, affectionate temperament, and lively personality. Most weigh between 4–7 pounds and often live well into their teens, with many reaching 13–15 years or more when well cared for.
Key breed traits:
– Size: Toy breed, light-boned, small frame
– Temperament: Affectionate, people-oriented, often “Velcro” dogs
– Lifestyle: Typically indoor companions, low to moderate exercise needs
– Typical lifespan: Around 12–15 years, sometimes longer
Overall, the Maltese is not generally listed among the very highest cancer-risk breeds (like some large and giant breeds). However, like all long-lived small dogs, age-related cancers can still be a significant issue, especially after about 8–10 years of age. In particular, veterinarians commonly see:
– Mammary gland tumors (especially in females that were never spayed or spayed later in life)
– Various skin lumps and bumps
– Oral and dental-area growths
– Certain internal cancers that may appear with advanced age
Because they often live longer, Maltese have more years of life in which cancer can develop, making senior-care monitoring especially important.

B. Tumor and Cancer Risks for This Breed
Common cancers in this breed
While every dog is an individual, the following tumor types are among the more commonly encountered in Maltese:
1. Mammary (breast) tumors
– Most often seen in intact or late-spayed females.
– Risk is strongly linked to hormone exposure over time.
– These can be benign or malignant, which is why any mammary lump needs prompt veterinary evaluation.
2. Skin and subcutaneous (under-the-skin) tumors
– Lipomas (fatty tumors) can occur, as in many older dogs.
– Other skin tumors (such as mast cell tumors or other growths) are less predictable and can vary.
– Because Maltese have white coats and pink skin, owners may notice small bumps earlier if they groom and handle the dog regularly.
3. Oral and gum tumors
– Small breeds, including Maltese, are prone to dental disease, chronic inflammation, and poor mouth health, which can complicate detection of oral growths.
– Tumors in the mouth or on the gums may first be seen as a lump, bad breath, drooling, or reluctance to chew.
4. Testicular tumors (in intact males)
– Intact male Maltese, especially those with retained (undescended) testicles, are at higher risk.
– These tumors may be noticed as a change in testicle size or firmness, or discovered during a routine exam.
5. Lymphoma and internal organ cancers
– Like all breeds, Maltese can develop lymph node cancers or tumors of organs such as the spleen, liver, or digestive tract, generally emerging in middle age or later.
– These may be harder to detect at home early and often show up first as vague signs like weight loss, decreased appetite, vomiting, or lethargy.
Factors that may influence Maltese cancer risks
Several characteristics of the Maltese may play a role in risk patterns:
– Small body size and long lifespan: Their long lives mean more years for age-related changes, including cancer.
– Reproductive status:
– Females not spayed early in life have significantly higher risk of mammary tumors.
– Intact males, especially with retained testicles, have higher risk of testicular tumors.
– Coat color and skin:
– The white coat and light skin may make some skin problems easier to see, but can also be more sensitive to sun if dogs spend a lot of time outdoors.
– Dental and oral health:
– Toy breeds, including Maltese, are very prone to dental disease, which can mask or mimic early oral tumors.
Knowing these tendencies helps you focus your at-home checks and discussions with your veterinarian.

C. Early Warning Signs Owners Should Watch For
Catching potential cancer early can greatly improve comfort, treatment options, and outcomes. Maltese are small, so even a relatively small tumor can have a big impact on their health.
Early tumor symptoms in Maltese dogs
Watch for the following changes and bring them to your vet’s attention promptly:
1. New or changing lumps and bumps
– Any new skin lump, especially if:
– Grows quickly
– Changes color
– Feels firm, irregular, or fixed in place
– Ulcerates, bleeds, or oozes
– Any swelling along the mammary chain (belly area of female dogs), even tiny nodules.
2. Weight and appetite changes
– Gradual or sudden weight loss with normal or decreased appetite.
– Reluctance to eat hard kibble or chewing on one side of the mouth.
– Increased thirst or urination can also be a sign of internal disease.
3. Behavior and energy level
– A once-bouncy Maltese who seems consistently tired, withdrawn, or less playful.
– Difficulty climbing stairs, jumping onto the sofa, or going for usual walks.
– General “slowing down” that seems beyond normal aging.
4. Mobility or pain signs
– Limping, stiffness, or sensitivity when touched in certain areas.
– Reluctance to be picked up or groomed.
– Crying or yelping unexpectedly.
5. Bleeding, coughing, or odd discharges
– Nosebleeds, coughing (especially if persistent or worsening), or difficulty breathing.
– Unusual vaginal discharge in intact females.
– Blood in urine or stool.
6. Mouth-related signs
– Bad breath that seems worse than typical “doggy breath.”
– Drooling more than usual.
– Visible mass on the gums, lips, or inside cheeks.
At-home monitoring tips
You can create a simple monthly routine:
– Full-body “pet and feel” check:
– Run your hands gently over your dog’s head, neck, chest, belly, legs, and tail.
– Note any new lumps or changes in existing ones.
– Mammary check for females:
– Gently feel along the belly from chest to groin. Look and feel for small pea-sized nodules or larger masses.
– Mouth and teeth glance:
– If your Maltese tolerates it, lift the lips to inspect the gums and teeth.
– Track trends:
– Keep a simple notebook or phone log for weight, appetite, energy, and any lumps.
– Know when to call the vet:
– Any new lump persisting more than 1–2 weeks.
– Rapidly growing or painful masses.
– Ongoing weight loss, decreased appetite, or persistent coughing, vomiting, or diarrhea.
Prompt veterinary assessment doesn’t mean it is cancer—many lumps are benign—but it ensures you don’t miss something important.

D. Senior Care Considerations for Maltese
As Maltese age, cancer risk naturally increases, along with other issues such as heart disease, dental disease, and arthritis. Thoughtful senior care can make a big difference in comfort and early detection.
How aging affects the Maltese
Older Maltese may experience:
– Reduced muscle mass and slower metabolism
– Increased risk of chronic diseases (heart, kidney, endocrine)
– Slower recovery from illness or surgery
– Higher chance of developing tumors or cancer
Because they are small and often stoic, subtle changes can be easily overlooked, so intentional monitoring is essential.
Nutrition and body condition
– Aim to keep your Maltese lean but not underweight—you should feel but not see ribs easily.
– Ask your vet about:
– Switching to a high-quality senior or adult maintenance food appropriate for your dog’s size and any existing health issues.
– Monitoring calorie intake if your dog is less active.
– Obesity can increase strain on joints, complicate surgery or anesthesia, and may be linked with higher cancer risk in general.
Exercise and activity adjustments
– Continue daily walks and gentle play, but adapt intensity to your dog’s stamina and any medical conditions.
– Several short walks may be better than one long outing.
– Mental stimulation (training games, sniffing walks, puzzle toys) helps maintain overall vitality.
Joint care and pain management
– Even small dogs can develop arthritis or joint discomfort.
– Discuss with your vet:
– Safe pain control options if needed
– Whether joint-supportive measures (like certain supplements or physical therapy) might be appropriate
– Avoid jumping from high furniture; use steps or ramps to protect joints and spine.
Veterinary check-ups and screening
For senior Maltese (often considered 8+ years):
– Wellness exams every 6 months are often recommended.
– Ask your vet about:
– Periodic bloodwork and urine tests
– Senior wellness panels or imaging (like X-rays or ultrasound) if indicated
– Specific cancer or organ function screening tailored to your dog’s history
Regular visits give your veterinarian the chance to detect subtle changes long before they become obvious problems at home.
—
E. General Tumor Prevention & Wellness Support
No approach can guarantee that a Maltese will never develop cancer, but supporting overall health and reducing known risk factors can be helpful.
Weight management
– Keep your dog at a healthy, lean body condition.
– Measure food portions and limit high-calorie treats.
– Use healthy training rewards like small pieces of your dog’s regular kibble or vet-approved snacks.
Diet and hydration
– Provide a balanced, complete diet appropriate for size, age, and health status.
– Fresh water should be available at all times.
– If considering home-cooked or specialized diets, work with a veterinarian or board-certified veterinary nutritionist to ensure proper nutrient balance.
Regular physical activity
– Daily, gentle exercise supports:
– Heart and circulation
– Digestive health
– Muscle tone and joint function
– For Maltese, consistency is more important than intensity. Short, regular walks and play are ideal.
Environmental and lifestyle considerations
– Avoid excessive sun exposure, especially for light-skinned areas like the nose and belly.
– Keep your dog away from:
– Tobacco smoke
– Pesticide-treated lawns, if possible
– Known toxic substances (certain plants, chemicals, rodent poisons)
Natural and integrative wellness supports
Some owners are interested in supplements or integrative wellness strategies (such as omega-3 fatty acids, certain herbs, or joint-support products) to support overall health. These may sometimes be part of a broader wellness plan, but:
– They should never be used in place of veterinary care.
– Always discuss any supplement, herb, or over-the-counter product with your veterinarian first, especially for a senior Maltese or one with existing diseases or on medications.
– Be cautious of any product or claim that promises to “cure” cancer or “shrink tumors.”
—
F. Integrative and Holistic Care as a Complement
Some families explore integrative or holistic approaches to support their Maltese’s comfort and resilience, especially if a tumor or cancer has been diagnosed.
Examples of supportive approaches (used alongside conventional care) can include:
– Acupuncture for pain management or general well-being
– Gentle massage or physical therapy for mobility and comfort
– Mindful, balanced nutrition plans developed with veterinary guidance
– Stress-reduction strategies, such as maintaining a predictable routine and a calm home environment
These methods aim to support the whole dog—body and mind—rather than treat cancer itself. Any integrative program should be coordinated with your primary veterinarian or a veterinary oncologist, so that it complements (and does not interfere with) standard diagnostics or treatments.
—
Conclusion
Maltese are long-lived, loving companions, which means they are also more likely to face age-related issues, including tumors and cancer. By understanding key Maltese cancer risks, staying alert to early tumor symptoms in Maltese dogs, and monitoring for common cancers in this breed—especially in seniors—you can catch problems earlier and support better quality of life. Partner closely with your veterinarian, keep up with regular check-ups, and use breed-aware, proactive care to help your Maltese stay as happy and comfortable as possible throughout their golden years.
by TCMVET | Dec 14, 2025 | Dog Cancer & Tumors
Maltese cancer risks, early tumor symptoms in Maltese dogs, common cancers in this breed are topics many owners don’t think about until their dog is already a senior. Yet understanding how this small, long-lived breed ages—and what warning signs to watch for—can make a real difference in quality of life and early detection.
—
A. Breed Overview: The Maltese in a Health Context
The Maltese is a toy breed known for its silky white coat, affectionate nature, and surprisingly bold personality. Typically weighing 4–7 pounds and living 12–15 years or more, they are often described as lively, devoted, and people-oriented companions.
Key characteristics that matter for health and cancer risk:
– Size: Toy breed, long lifespan, which means more years for age-related diseases (including tumors) to develop.
– Coat and color: Pure white coat and often pink or lightly pigmented skin can contribute to sensitivity to sun exposure.
– Temperament & lifestyle: Usually indoor dogs, often carried or walked on leash; this can lower some injury risks but doesn’t eliminate health issues.
Maltese are not among the very highest-risk breeds for cancer overall, but studies and clinical experience suggest they may be more prone to:
– Mammary (breast) tumors, especially in intact females
– Certain skin and oral tumors
– Age-related cancers due to their long lifespan
Knowing these tendencies allows owners to be more proactive with screening and senior care.
—
B. Tumor and Cancer Risks for the Maltese
While any dog can develop cancer, some patterns appear more often in this breed. Below are several of the more commonly noted tumor types in Maltese, along with simple explanations of risk factors.
1. Mammary (Breast) Tumors
In small-breed, intact female dogs, mammary tumors are very common, and the Maltese is no exception.
– Who’s at risk: Females that were never spayed, or spayed later in life.
– Why: Hormone exposure over many heat cycles can stimulate mammary tissue growth and abnormal cell changes.
– What owners may notice: Firm or soft nodules along the “chain” of mammary glands (from chest to groin), sometimes single, sometimes multiple.
Early spaying greatly reduces the risk of mammary tumors, but it does not completely eliminate it if done later. Any new lump near the nipples should be checked promptly.
2. Skin Tumors (Benign and Malignant)
Maltese have pale skin under their white coat, which can be more sensitive to UV light, especially on:
– Nose
– Ears
– Belly (if hair is thin)
– Areas where hair is clipped short
Common skin tumors in small breeds can include:
– Mast cell tumors
– Soft tissue sarcomas
– Benign growths such as lipomas (fatty tumors) or sebaceous adenomas
While many skin lumps are harmless, some are not. Because this breed is often groomed regularly, owners are in a good position to spot changes on the skin early.
3. Oral Tumors
Some reports suggest small breeds, including Maltese, may be overrepresented in certain oral cancers such as oral melanoma or other mouth tumors.
– Risk factors: Chronic dental disease, inflammation, and age may play a role.
– Possible signs: Bad breath that worsens, bleeding from the mouth, visible masses on the gums, or difficulty eating.
Since Maltese are predisposed to dental problems generally, regular mouth checks are especially important.
4. Lymphoma
Lymphoma is a common cancer in dogs of many breeds, and Maltese are no exception.
– What it is: A cancer of lymphocytes, a type of white blood cell.
– Where it can show up: Lymph nodes, spleen, liver, or other organs.
– Owner-visible signs: Swollen lymph nodes under the jaw, in front of the shoulders, or behind the knees, plus lethargy, weight loss, or decreased appetite.
5. Urinary and Other Age-Related Tumors
Older Maltese can also develop tumors in the bladder, liver, spleen, or other organs, simply as a result of aging and cell wear-and-tear over time. These may not be breed-specific, but the Maltese’ long lifespan means owners are relatively more likely to face age-related tumors at some point.
—
C. Early Warning Signs Owners Should Watch For
Early tumor symptoms in Maltese dogs can be subtle at first. Because they are small and often carried or doted on, small changes may be overlooked or mistaken for “getting older.”
1. Lumps, Bumps, and Skin Changes
Check your Maltese regularly during grooming or cuddling:
– Run your hands gently over the entire body once a month.
– Feel along the mammary chain in females.
– Look at the skin on the ears, nose, and belly for:
– New dark or red spots
– Scabs or sores that don’t heal
– Thickened or crusty areas
When to call your vet:
– Any lump that is new, growing, changing, painful, or ulcerated
– Any sore or scab that does not heal within 2–3 weeks
2. Weight, Appetite, and Energy Changes
Because Maltese are small, even small changes can be meaningful:
– Unintentional weight loss
– Decreased appetite or pickiness that is new
– Lethargy, sleeping more, or reluctance to play or walk
– Panting more or seeming uncomfortable at rest
Sudden or steady changes over a few weeks warrant a veterinary visit, especially in a dog over 7–8 years old.
3. Mobility, Pain, and Behavior
Tumors affecting bones, nerves, or internal organs can cause:
– Lameness or limping
– Difficulty jumping onto furniture
– Stiffness when getting up
– Hiding, irritability, or not wanting to be touched in certain areas
Any persistent pain or mobility issue should be evaluated.
4. Bleeding, Coughing, and Other Red Flags
Watch for:
– Bleeding from the mouth, nose, or rectum
– Persistent cough or trouble breathing
– Straining to urinate or blood in the urine
– Vomiting or diarrhea that keeps recurring
These signs do not mean a dog definitely has cancer, but they do indicate a need for timely veterinary assessment.
—
D. Senior Care Considerations for the Maltese
As Maltese age, their risk for tumors and other chronic conditions naturally increases. Thoughtful senior care can help detect problems earlier and keep them comfortable.
1. How Aging Affects Maltese
Typical aging changes include:
– Slower metabolism and tendency to gain weight if diet is not adjusted
– More fragile joints and possible arthritis
– Declining organ function (kidneys, liver, heart)
– Weaker immune system and slower healing
Because cancer is largely a disease of older cells, these age-related shifts can overlap with increased tumor risk.
2. Nutrition and Body Condition
For senior Maltese (often starting around 8–10 years):
– Aim for a slim but not skinny body condition; you should feel ribs easily but not see them sharply.
– Use a senior-appropriate diet recommended by your veterinarian, taking into account:
– Weight management
– Dental health
– Any kidney, liver, or heart issues
Avoid crash diets. If weight loss is unintentional, this is a reason for a check-up, not just a feeding change.
3. Exercise and Activity Adjustments
Gentle, consistent activity supports joint health, digestion, and mood:
– Daily short walks
– Light play sessions on non-slippery surfaces
– Avoiding high-impact jumps from beds or sofas (use steps or ramps instead)
Monitor for coughing, heavy panting, or limping and discuss these with your veterinarian.
4. Joint Care and Pain Management
Senior Maltese may show subtle pain:
– Hesitation before climbing stairs
– Reluctance to jump
– Seeming “grumpy” when picked up
Discuss options such as:
– Environmental changes (ramps, rugs, soft bedding)
– Veterinary-approved pain management strategies
– Possible joint-support supplements, only under veterinary guidance
5. Check-Up Intervals and Screening
For a healthy adult Maltese, annual exams are typical. Once they become seniors:
– Consider twice-yearly wellness visits, particularly after age 8–10.
– Ask about routine screening such as:
– Bloodwork and urinalysis
– Dental evaluations
– Imaging (X-rays or ultrasound) when indicated
These visits create a baseline, so small changes are easier to spot and investigate early.
—
E. General Tumor Prevention & Wellness Support
No strategy can guarantee that a Maltese will never develop cancer, but you can lower some risks and support overall resilience.
1. Maintain a Healthy Weight
Excess body fat is linked to inflammation and may increase the risk or severity of various diseases.
– Use a measuring cup for food.
– Limit high-calorie treats.
– Ask your vet for your dog’s ideal weight range and how to achieve it safely.
2. Diet and Hydration
Aim for:
– A complete and balanced diet appropriate for size, age, and health status.
– Fresh water available at all times.
– Avoiding frequent high-fat table scraps, which can upset the pancreas and add unnecessary calories.
Some owners explore foods rich in antioxidants or omega-3 fatty acids. While these may support general health, they should not be viewed as cancer treatments. Always discuss diet changes and supplements with your veterinarian.
3. Regular Physical Activity
Movement supports:
– Cardiovascular health
– Digestive function
– Muscle mass and joint function
– Mental well-being
Even 2–3 short walks plus gentle play each day can be enough for many Maltese, adjusted to your dog’s abilities.
4. Sun and Environmental Exposure
Because of their pale skin:
– Avoid prolonged midday sun, especially for dogs with thin coats or shaved areas.
– Use shaded areas and limit time on hot surfaces.
– Talk to your vet before using any pet-safe sunscreen on sensitive areas like the nose and ears.
Minimize exposure to:
– Secondhand smoke
– Harsh lawn chemicals and strong household cleaners
– Unnecessary pesticides in the yard
These measures may reduce overall toxic burden, although they cannot guarantee prevention.
5. Thoughtful Use of Supplements
Common interest areas include:
– Joint-support supplements
– General wellness blends
– Herbal or “immune-support” products
These should be:
– Selected with veterinary guidance
– Checked for safety, dosing for toy breeds, and interactions with any medications
No supplement should be used in place of diagnostic work-ups or conventional treatments recommended by your veterinarian.
—
F. Integrative and Holistic Support (As a Complement Only)
Some families consider integrative approaches to help their Maltese feel as well as possible during cancer treatment or in senior years. These might include:
– Gentle acupuncture to support comfort and mobility
– Massage or physical therapy for stiffness and muscle maintenance
– Carefully chosen herbal or nutritional support, under a veterinarian trained in integrative medicine
The goal of these approaches is to:
– Support overall vitality
– Help manage stress and discomfort
– Complement, not replace, modern diagnostics and oncology care
If you are interested in integrative options, look for a veterinarian with additional training in this area and always coordinate care with your primary vet or veterinary oncologist.
—
Conclusion
Maltese cancer risks, while not the highest among all breeds, are real—especially for intact females (mammary tumors), senior dogs, and those with long-standing dental or skin issues. Watching for early tumor symptoms in Maltese dogs, such as new lumps, weight or appetite changes, and subtle shifts in energy or behavior, gives you the best chance of catching problems sooner. With regular veterinary check-ups, breed-aware senior care, and thoughtful wellness habits, you can help your Maltese enjoy as many healthy, comfortable years with you as possible.
by TCMVET | Dec 14, 2025 | Dog Cancer & Tumors
Maltese cancer risks, early tumor symptoms in Maltese dogs, common cancers in this breed are important topics for any Maltese owner who wants to protect their tiny companion into their senior years. While these cheerful lapdogs often enjoy long lives, their small size and certain genetic tendencies mean that some tumors and cancers are more likely than others, especially as they age.
—
A. Breed Overview: The Maltese at a Glance
The Maltese is a toy breed known for its long, silky white coat, bright expression, and affectionate, people-oriented personality. Most weigh between 4–7 pounds and live, on average, 12–15 years, with many reaching their mid-teens with good care.
Key traits that matter for health and cancer risk:
– Size: Very small, light-boned toy breed
– Coat & color: Solid white, single coat (no undercoat)
– Temperament: Loving, playful, often “velcro” dogs that bond closely to their families
– Lifestyle: Primarily indoor companions, with short walks and play sessions
While the Maltese is not among the very highest-risk breeds for cancer overall, they do appear to have increased risk for certain tumor types, particularly:
– Mammary (breast) tumors in females, especially those not spayed early
– Oral and dental-area tumors (their small mouths and dental disease tendencies may play a role)
– Skin and subcutaneous lumps, including both benign and malignant growths, in middle-aged and older dogs
Understanding these tendencies helps you stay alert for subtle changes, especially as your Maltese moves into their senior years.
—
B. Tumor and Cancer Risks for This Breed
1. Mammary (Breast) Tumors
In small female breeds like the Maltese, mammary tumors are among the most common cancers, especially if they were never spayed or were spayed later in life.
Factors involved:
– Hormones: Repeated heat cycles and lifetime exposure to estrogen and progesterone strongly increase the chance of mammary gland tumors.
– Age: Most mammary tumors appear in middle-aged to older females (often 7+ years).
– Spay timing: Dogs spayed before their first or second heat have a dramatically lower risk compared to those spayed later or never spayed.
These tumors can range from benign to highly malignant; only a veterinarian can determine which is which through proper testing.
2. Skin Lumps and Subcutaneous Tumors
Maltese are long-lived, and as they age, they are prone to various skin and just-under-the-skin masses, including:
– Benign growths like lipomas (fatty tumors) or sebaceous adenomas
– Potentially malignant tumors such as mast cell tumors or soft tissue sarcomas
Their white coat can make small lumps harder to spot unless you regularly run your hands along the body. Some tumors may look like harmless “bumps” at first, which is why early veterinary checks of new lumps are so important.
3. Oral and Dental-Associated Tumors
Because Maltese commonly struggle with dental disease, chronic inflammation in the mouth may contribute to a higher risk of certain oral tumors in older dogs, such as:
– Malignant melanomas inside the mouth
– Squamous cell carcinomas along the gums or tongue
– Other gum or jaw tumors
Owners may first notice bad breath, drooling, or reluctance to chew hard food—symptoms that can be caused by both dental disease and oral masses.
4. Lymphoma and Other Internal Cancers
Like many breeds, Maltese can develop lymphoma (cancer of the lymphatic system) or internal tumors such as:
– Tumors in the spleen, liver, or intestines
– Bladder or urinary tract tumors (less common but possible)
Their small size means that even relatively small internal tumors may start to affect appetite, energy, or body weight sooner than in a large breed.
5. Testicular Tumors in Intact Males
Unneutered male Maltese may develop testicular tumors as seniors. These are often discovered when:
– A testicle becomes enlarged, firm, or oddly shaped
– One testicle seems to shrink while the other grows
Cryptorchid males (one or both testicles retained in the abdomen) are at especially high risk for testicular tumors in the retained testicle.
—
C. Early Warning Signs Owners Should Watch For
Knowing the early tumor symptoms in Maltese dogs can help you seek help quickly. Never ignore subtle changes, especially in a senior dog.
Common Early Signs
Watch for these changes at home:
– New lumps or bumps
– Any new mass under the skin or on the body
– A previously stable lump that starts to grow, change shape, or ulcerate
– Changes in appetite or weight
– Eating less, becoming pickier, or walking away from meals
– Gradual weight loss, visible ribs, or loss of muscle along the back
– Low energy or behavior changes
– Less interest in play or walks
– Hiding, restlessness, or seeming “not quite themselves”
– Pain or mobility problems
– Reluctance to jump onto furniture
– Limping, stiff walking, or reluctance to go up/down stairs
– Mouth and facial signs
– Drooling, bad breath that worsens, or difficulty picking up kibble
– Bleeding from the mouth, swelling in the jaw or face
– Breathing and coughing
– Persistent cough not linked to excitement or pulling on the leash
– Fast or labored breathing at rest
– Bleeding or discharge
– Unexplained bruises or bleeding from nose, mouth, or rectum
– In females: discharge from the vulva, especially if spayed
At-Home Monitoring Tips
Create a simple monthly routine:
1. Hands-on body check:
– Gently run your hands over the entire body: head, ears, neck, chest, belly, legs, tail.
– Note the location and size of any lumps; compare month to month.
2. Mouth check:
– Look at gums and teeth if your dog allows.
– Report any masses, severe redness, or one area that looks different from the rest.
3. Weight and appetite log:
– Weigh your Maltese every 4–6 weeks if possible.
– Keep mental or written notes about appetite, interest in food, and treat intake.
4. Behavior and mobility:
– Notice how easily they jump, climb, and move around the house.
– Note any increased sleeping or reluctance to engage.
When to See the Veterinarian Promptly
Contact your vet as soon as possible if you notice:
– Any new lump lasting more than 1–2 weeks
– A lump that doubles in size within a month or becomes painful, red, or ulcerated
– Unexplained weight loss, persistent vomiting, or diarrhea
– Ongoing cough, breathing difficulty, or collapse
– Bleeding from the mouth, nose, rectum, or genitals
– Sudden big change in energy level, behavior, or mobility
Your veterinarian can perform a physical exam and may recommend tests like needle sampling of lumps, bloodwork, or imaging. These steps help determine the best next move; they are not something you can safely guess at home.

D. Senior Care Considerations for the Maltese
As Maltese age, their long lifespan means more years for wear-and-tear conditions and tumors to develop. Thoughtful senior care can improve comfort and support early detection.
How Aging Affects This Breed
Senior Maltese (often 8+ years) may show:
– More dental problems and related oral inflammation
– Stiffness or joint discomfort, especially in knees and spine
– Slower metabolism and tendency to gain weight
– More fragile immune system, making them less resilient to illness
All of these factors can interact with tumor risk, either directly (chronic inflammation) or indirectly (reduced ability to bounce back from illness).
Nutrition and Body Condition
Focus on:
– Appropriate calories: Maintain a lean but not skinny frame; you should feel ribs easily but not see them prominently.
– High-quality protein: Helps maintain muscle mass, critical for older, small dogs.
– Dental-friendly texture: Some seniors benefit from softer food if dental disease or missing teeth make chewing hard kibble painful.
Discuss with your veterinarian which senior or maintenance diet is best for your dog’s individual needs and other health conditions.
Exercise and Activity Adjustments
Maltese remain playful well into old age but may need:
– Shorter, more frequent walks instead of long outings
– Gentle indoor play, puzzle toys, and mental enrichment
– Non-slip rugs to help with traction on slippery floors
Regular, moderate activity helps manage weight, supports joint health, and can make it easier to notice if they suddenly slow down or limp.
Joint Care and Pain Management
Many older Maltese develop some degree of osteoarthritis or joint discomfort. Signs can mimic or mask cancer-related pain, so it’s vital to:
– Mention any stiffness, limping, or reluctance to jump at vet visits
– Discuss options like joint-supportive diets, environmental changes (ramps, steps), and veterinary-guided pain management if needed
Never give human pain medication without veterinary guidance; some are toxic to dogs.
Wellness Exams and Screening
For a senior Maltese, a reasonable general schedule to discuss with your veterinarian is:
– Twice-yearly wellness exams (every 6 months)
– Periodic bloodwork and urinalysis, especially in dogs with chronic conditions
– Routine oral exams and dental cleanings as advised
– Prompt evaluation of any new lumps, behavior changes, or weight loss
These visits are opportunities to catch issues early, adjust care plans, and talk through any concerns about cancer risk.
—
E. General Tumor Prevention & Wellness Support
While no approach can guarantee that a Maltese will never develop cancer, several lifestyle strategies may help support overall health and reduce certain risk factors.
Maintain a Healthy Weight
Obesity is linked to increased inflammation and various health problems. For a tiny breed:
– Even an extra pound is a significant percentage of body weight.
– Use treats sparingly; choose healthy options and small pieces.
– Adjust food portions as your dog’s activity level changes with age.
Balanced Diet and Hydration
Offer:
– Complete, balanced dog food appropriate for age and health status
– Fresh water available at all times
– Consistent feeding schedule to make appetite changes easier to spot
If you’re considering home-prepared or specialized diets, always work with your veterinarian or a board-certified veterinary nutritionist to avoid nutrient imbalances.
Regular Physical Activity
Daily, gentle exercise can:
– Help maintain muscle mass and joint flexibility
– Support cardiovascular health
– Improve mental well-being and reduce stress
Adjust the intensity to your dog’s abilities; short, frequent sessions are usually ideal for small seniors.
Dental Care
Because mouth health is a key issue in Maltese and may relate to some oral tumors:
– Brush teeth regularly if your dog tolerates it
– Use vet-approved dental products
– Schedule professional dental cleanings as recommended
Healthy gums and teeth reduce chronic inflammation and make it easier to spot unusual masses early.
Minimize Environmental Risks
Where practical:
– Avoid exposure to secondhand smoke
– Be cautious with lawn chemicals, pesticides, and harsh household cleaners
– Protect sensitive white skin from intense sun if your Maltese spends time outdoors, especially around the nose and ears
Supplements and Natural Support
Some owners consider joint supplements, omega-3 fatty acids, or other wellness products for overall support. These may have benefits for general health, but:
– They should never be viewed as a cure or primary treatment for tumors or cancer.
– Always discuss any supplement, herb, or natural product with your veterinarian first to check for safety, interactions, and appropriate use.

F. Optional Integrative Care: Supporting Overall Resilience
Integrative or holistic approaches, such as acupuncture, massage, or Traditional Chinese Medicine–inspired concepts, are sometimes used alongside conventional veterinary care for dogs with chronic illness, including cancer.
Possible roles of integrative care:
– Supporting overall comfort and quality of life
– Helping manage stress, mobility, or appetite in some dogs
– Encouraging a sense of routine and calm in both dog and owner
Any such approach should:
– Be coordinated with your primary veterinarian or a veterinary oncologist, especially if your Maltese has a diagnosed tumor or is undergoing treatment
– Be seen as complementary, not a replacement for evidence-based diagnostics and therapies
– Avoid promises of cures or guaranteed outcomes
Choosing experienced, licensed practitioners is essential for safety.

A. Breed Overview: The Maltese and Long-Term Health
The Maltese is a toy breed known for its silky white coat, affectionate personality, and surprisingly bold attitude. Most weigh between 4–7 pounds and live, on average, 12–15 years, with many reaching their mid‑teens when well cared for.
Typical traits include:
– Very people‑oriented and often attached to one or two family members
– Moderate energy indoors, with short bursts of play
– Prone to dental disease and tear staining
– Generally sturdy for their size, but still delicate compared with larger breeds
From current data, Maltese dogs are not usually listed among the very highest‑risk breeds for cancer overall (like Boxers or Golden Retrievers). However, because they live a long time, they do face increased risk of certain tumors as seniors, especially:
– Skin and subcutaneous (under the skin) lumps
– Oral (mouth) tumors
– Mammary (breast) tumors in unspayed females
– Blood‑related cancers such as lymphoma
So while cancer may not be the first health concern people think of with Maltese, it is an important issue to watch for as your dog ages.

B. Tumor and Cancer Risks for Maltese Dogs
1. Skin and Subcutaneous Masses
Small, older dogs commonly develop skin lumps, and Maltese are no exception. Common possibilities include:
– Benign (non‑cancerous) fatty tumors (lipomas)
– Sebaceous (oil gland) growths
– Mast cell tumors (which can be low‑ or high‑grade cancers)
Because the Maltese coat is long and thick, small lumps can be hidden under the hair and missed until they are large. Also, their light skin can be sensitive to chronic irritation or sun exposure, especially on sparsely haired areas like the nose or belly.
2. Oral and Dental‑Area Tumors
Maltese are prone to crowded teeth and dental disease, which can go hand‑in‑hand with:
– Gum overgrowth or benign mouth masses
– Oral tumors affecting the gums, tongue, or jaw
Not all mouth lumps are cancerous, but some oral tumors in dogs can be aggressive. In small breeds like the Maltese, any change in the mouth is worth checking because even benign but fast‑growing lesions can interfere with eating or cause pain quickly due to their tiny mouths.
3. Mammary (Breast) Tumors in Females
Unspayed female Maltese, or those spayed later in life, have a higher risk of developing tumors in the mammary glands. These can be:
– Benign nodules
– Malignant (cancerous) tumors that can spread
Toy breeds in general, including Maltese, have been reported with mammary tumors relatively often when left intact. Early spaying (before the first or second heat cycle) greatly reduces this risk, but decisions around spaying should always be made with your veterinarian.
4. Lymphoma and Other Blood Cancers
While not uniquely high in Maltese, lymphoma and related cancers can occur in this breed, especially in middle‑aged and older dogs. These cancers affect the lymphatic system and can cause:
– Enlarged lymph nodes
– Generalized illness, weight loss, or lethargy
Again, this is not to say your Maltese is “likely” to get lymphoma, but that it is one of the more common cancers seen across many breeds, including small dogs.
5. Age and Size Factors
Several physiological factors influence cancer risk in Maltese:
– Small size: Smaller dogs often live longer, giving more years in which cancer can develop.
– Long lifespan: The longer the life span, the greater the cumulative risk of tumors and degenerative diseases.
– Coat color and skin: Their white coat and pale skin can be more vulnerable to sun damage if they spend a lot of time outside without shade.
None of these factors guarantee cancer will occur, but they are useful for understanding why vigilant monitoring becomes especially important in the senior years.

C. Early Warning Signs of Cancer in Maltese Dogs
Recognizing early changes is key. Many tumors in dogs are only detected once an owner notices something “off” at home.
Lumps, Bumps, and Skin Changes
Watch for:
– New lumps anywhere on the body
– Existing lumps that grow, change shape, or ulcerate (break open)
– Areas of thickening, redness, or sores that don’t heal
Practical at‑home tip:
– Do a monthly “hands‑on” check:
– Gently run your fingers over the whole body, including the chest, armpits, belly, and along the legs.
– Part the hair to look at the skin, especially on the belly, inner thighs, and around the tail.
– Keep a simple “lump diary”: note the date, location, and approximate size (e.g., “pea‑sized lump on right chest”).
Any new lump or one that changes quickly should be evaluated by a veterinarian.
Changes in Eating, Weight, or Energy
Subtle shifts can be early indicators of a deeper issue:
– Decreased appetite or picky eating
– Weight loss despite normal food intake
– Increased thirst or urination
– Sleeping more or reluctance to play or go for walks
Because Maltese are small, even modest weight loss is noticeable if you weigh them regularly at home or at the vet.
Mobility, Pain, and Behavior Changes
Even though Maltese aren’t large dogs, tumors in the bones, spine, or internal organs can cause:
– Limping or reluctance to jump up on furniture
– Stiffness when getting up
– Hiding, irritability, or resistance to being picked up
Any ongoing discomfort should prompt a vet visit, especially if it seems to worsen over days or weeks.
Bleeding, Coughing, or Other Alarming Signs
Contact your vet promptly if you notice:
– Bleeding from the mouth, nose, or rectum
– Persistent coughing or trouble breathing
– Repeated vomiting or diarrhea
– A swollen abdomen or sudden collapse
These can be associated with many conditions, including cancer, and all warrant immediate veterinary attention.

D. Senior Care Considerations for Maltese
As a long‑lived toy breed, Maltese often spend several years in a “senior” phase. Cancer risk tends to climb from about 8–10 years of age onward, though it can occur earlier.
Nutrition and Body Condition
Maintaining an ideal body weight is one of the most important things you can do:
– Avoid obesity: Extra pounds stress joints and organs and may increase inflammation.
– Prevent being underweight: Sudden or unexplained weight loss can be a red flag and should be evaluated.
Ask your veterinarian:
– What body condition score (BCS) is ideal for your dog
– Whether a senior‑formulated diet or a specific therapeutic diet is appropriate
Exercise and Daily Activity
Even seniors benefit from regular movement:
– Short, gentle walks once or twice a day
– Playtime with soft toys or low‑impact indoor games
– Avoiding high jumps off furniture to protect joints and spine
Guideline: Adjust exercise based on your Maltese’s stamina—tired but content after activity is good; panting heavily, limping, or refusing to move is a sign to scale back and consult your vet.
Joint Care and Pain Management
Maltese can develop arthritis and knee issues (such as luxating patellas) as they age, which may be complicated if tumors develop near joints or bones.
Support may include:
– Soft bedding and traction mats to prevent slipping
– Ramps or steps to help with getting on and off furniture
– Vet‑recommended pain management strategies if arthritis is present
Never start pain medications without veterinary guidance; some over‑the‑counter human drugs are toxic to dogs.
Vet Check‑Ups and Screening
For senior Maltese, a good general guideline is:
– Wellness exams every 6 months
– Baseline bloodwork and urinalysis annually (or as recommended)
– Oral exams and dental cleanings on a schedule tailored to their mouth health
Ask your veterinarian whether additional screening—such as chest X‑rays or abdominal ultrasounds—is recommended based on age, physical exam findings, or any emerging signs.

E. General Tumor Prevention & Wellness Support
While you cannot fully prevent cancer, you can support your Maltese’s overall health and reduce some risk factors.
Healthy Weight and Diet
– Feed an appropriate, complete, and balanced diet recommended by your vet.
– Measure meals rather than “free feeding” to prevent weight gain.
– Limit high‑calorie treats; use small, healthy rewards like pieces of kibble or vet‑approved snacks.
Any changes in diet, including “natural” or homemade plans, should be discussed with your veterinarian to ensure it’s nutritionally complete.
Hydration and Digestive Health
– Provide fresh water at all times.
– Monitor drinking and urination patterns; sudden changes deserve a check‑up.
– If adding fiber, probiotics, or other digestive aids, do so only after consulting your vet.
Regular Physical Activity and Mental Stimulation
– Gentle daily walks help circulation and weight control.
– Puzzle feeders, scent games, and training refreshers keep their minds active.
– Keeping stress levels low—with predictable routines and calm interactions—may also support overall wellbeing.
Reducing Environmental Stressors
You may be able to limit certain exposures:
– Avoid second‑hand smoke around your dog.
– Use pet‑safe cleaners and avoid harsh chemicals where your Maltese spends time.
– Limit intense midday sun exposure, particularly on white, thinly haired skin; provide shade and consider brief outings instead of long sessions.
Supportive Supplements and “Natural” Approaches
Owners sometimes explore options like:
– Omega‑3 fatty acids for general inflammation support
– Antioxidant‑rich foods or supplements
– Joint supplements for older dogs with mobility issues
These may offer general wellness support for some dogs, but they:
– Do not replace medical care or veterinary oncology
– Have varying levels of scientific evidence
– Can interact with medications
Always talk with your veterinarian before starting any supplement, herb, or natural product.

F. Integrative and Holistic Support (Complementary, Not Alternative)
Some families are interested in integrative care—combining conventional veterinary medicine with holistic approaches—to support a Maltese living with tumors or cancer.
Examples might include:
– Acupuncture for comfort or mobility support
– Gentle massage or physical therapy to help maintain strength
– TCM‑inspired or herbal formulas aimed at supporting vitality and resilience
These approaches are best used:
– Under guidance of a vet experienced in integrative medicine
– Alongside, not instead of, recommended diagnostics and treatments
– With realistic expectations—focused on comfort and quality of life, not as a cure
If you’re interested in this route, ask your regular veterinarian for a referral to a certified veterinary acupuncturist or integrative practitioner.
