A. Breed Overview: The Maltese in a Health Context
The Maltese is a toy breed known for its long, silky white coat, friendly temperament, and deep attachment to its family. They are typically:
– Size: 4–7 pounds (2–3 kg), small and lightly built
– Temperament: Affectionate, people-oriented, often playful well into adulthood
– Lifespan: Commonly 12–15 years, sometimes longer with good care
– Common traits: White coat, dark eyes and nose, low-shedding, indoor-living companion
Because Maltese are generally long-lived, they spend many years in the “senior” stage of life. Longer lifespans naturally increase the chances of age-related diseases, including tumors and cancer.
Research and clinical experience suggest that:
– Toy breeds, including Maltese, may have slightly lower overall cancer rates than many large breeds, but they are still at risk.
– Maltese may be overrepresented for certain tumor types, particularly:
– Skin and subcutaneous (under-the-skin) tumors
– Mammary (breast) tumors in intact females
– Oral tumors
– Lymphoma, which can occur in any breed
Being a very light-colored, white-coated dog also raises concern for sun-related skin damage, which can contribute to some skin cancers, especially on unpigmented areas.

B. Maltese Cancer Risks, Early Tumor Symptoms in Maltese Dogs, Common Cancers in This Breed
While any type of cancer can occur in a Maltese, some patterns are more commonly seen.
1. Skin and Subcutaneous Tumors
Owners of Maltese should be especially tuned in to skin lumps and bumps, as their small size makes even modest growths more noticeable and potentially problematic.
Common issues include:
– Mast cell tumors:
These can appear as small or large skin lumps, sometimes itchy or inflamed. They may change size, becoming larger or smaller over days.
– Benign fatty lumps (lipomas):
Less common in toy breeds than big dogs, but still possible. Even benign lumps should be checked, as they can be confused with more serious tumors.
– Skin cancers like squamous cell carcinoma or melanoma:
Especially in sun-exposed, lightly pigmented areas (ears, nose, eyelids, belly, inner thighs).
Breed factors:
The Maltese’s white coat and often pink, lightly pigmented skin can increase vulnerability to UV damage, which may raise the risk of some skin cancers in sun-loving or frequently outdoor dogs.
2. Mammary (Breast) Tumors
Unspayed female Maltese are at higher risk of mammary tumors, which are among the most common tumors in intact female dogs.
– These can range from benign to highly malignant.
– Risk increases with age and number of heat cycles before spaying.
– Small breeds, including Maltese, are frequently represented among dogs with mammary masses.
Regularly feeling along your female Maltese’s mammary chain (from chest to groin) for small nodules, beads, or lumps is especially important if she was not spayed early in life.
3. Oral and Dental-Related Tumors
Toy breeds often develop dental disease due to crowded teeth and small mouths. Chronic inflammation and infection can complicate oral health and may be seen alongside:
– Oral melanoma
– Squamous cell carcinoma
– Other gum or jaw tumors
While not the most common cancers in Maltese, oral tumors are important because they’re easily overlooked until advanced. Bad breath, drooling, or difficulty eating are often blamed on “bad teeth” alone.
4. Lymphoma
Lymphoma is a cancer of the lymphatic system and can occur in any breed, including Maltese. It may show up as:
– Enlarged lymph nodes (under the jaw, in front of shoulders, behind knees)
– Lethargy, decreased appetite, or weight loss
– Occasionally stomach or intestinal signs
There is no clear proof that Maltese have a dramatically higher risk of lymphoma compared to other breeds, but their long lifespan means age-related cancers like lymphoma do appear.
5. Other Possible Cancers
Less frequently, Maltese may develop:
– Bladder tumors (like transitional cell carcinoma), often associated with urinary changes
– Liver or spleen tumors, which may present with vague symptoms like belly enlargement or collapse in severe cases
These are not uniquely “Maltese cancers,” but small, older dogs are not exempt from them.
—
C. Early Warning Signs Owners Should Watch For
Catching problems early can greatly improve your Maltese’s comfort and options for care. Watch for:
1. Skin and Body Changes
– New lumps or bumps anywhere on the skin
– Changes in existing lumps:
– Growing in size
– Becoming firmer or irregular
– Ulceration, bleeding, or scabbing
– Color changes on skin, lips, or gums
– Non-healing sores, especially on sun-exposed areas
At-home tip:
Once a month, when brushing or cuddling, gently run your fingers over your dog from nose to tail. Note:
– Location (for example “pea-sized bump behind right shoulder”)
– Size (compare to household objects: pea, grape, marble)
– Feel (soft/firm, movable/fixed)
If a lump persists more than a couple of weeks or changes noticeably, schedule a veterinary visit.
2. Changes in Appetite, Weight, or Energy
– Reduced appetite or picky eating
– Unexplained weight loss, even when eating normally
– Tiring easily, less interest in play or walks
– Sleeping much more than usual
Any lasting change in appetite, weight, or energy—especially in a senior Maltese—warrants discussion with your veterinarian.
3. Mobility, Pain, and Behavior Changes
– Reluctance to jump on furniture or climb stairs
– Stiffness, limping, or difficulty rising
– Whining, restlessness, or hiding
– Less willingness to be touched or carried
Pain can accompany some cancers (for example, bone tumors or internal tumors pressing on organs), but it can also result from non-cancer conditions like arthritis. Either way, these signs deserve attention.
4. Bleeding, Coughing, and Other Concerning Symptoms
– Persistent cough or trouble breathing
– Nosebleeds or bleeding from the mouth
– Bloody urine, straining to urinate, or frequent accidents
– Vomiting or diarrhea that lasts more than a couple of days
– Distended or tense abdomen
When to seek prompt veterinary care:
– Sudden collapse or extreme weakness
– Labored breathing or blue/pale gums
– Very fast-growing lump
– Persistent bleeding from any site
These can be urgent and should not wait.

D. Senior Care Considerations for Maltese
As Maltese age, they often remain bright and attached to their families but become more fragile physically. Aging and cancer risk go hand in hand, so a thoughtful senior-care plan is critical.
1. How Aging Affects Maltese
Common age-related changes include:
– Dental disease and tooth loss
– Heart disease (especially mitral valve disease)
– Joint stiffness, especially in the knees or back
– Slower metabolism and tendency to gain weight or lose muscle
These conditions can complicate surgery or anesthesia if a tumor is found, making prevention and early detection even more important.
2. Nutrition and Body Condition
For senior Maltese:
– Aim for a lean, but not thin body condition—ribs are easily felt but not seen.
– Choose high-quality, balanced food formulated for small or senior dogs, as appropriate.
– Monitor treats and table scraps carefully; obesity stresses joints, heart, and metabolism and may increase certain cancer risks.
Any diet changes, especially for dogs with existing health problems, should be discussed with your veterinarian.
3. Exercise and Activity Adjustments
Maltese generally enjoy gentle activity throughout life. For seniors:
– Continue daily walks, but keep them shorter and more frequent if needed.
– Provide low-impact play indoors.
– Avoid long exposure to hot or very cold weather.
Regular movement supports joint health, muscle mass, and weight control, all of which help your dog cope better with any health challenge, including cancer.
4. Joint Care and Pain Management
Even in the absence of cancer, aging joints can make your Maltese less active:
– Provide non-slip flooring or rugs to prevent slips.
– Use ramps or pet stairs to beds and couches instead of jumping.
– Ask your vet about:
– Pain-relief options
– Joint-supporting strategies (for example, specific diets or supplements—always vet-approved)
Comfortable, pain-controlled dogs are easier to examine and monitor, helping you and your vet catch health problems earlier.
5. Veterinary Checkups and Screening
For a senior Maltese (often considered senior around age 8–10):
– Twice-yearly wellness exams are typically recommended.
– Discuss appropriate screening tests, which may include:
– Bloodwork and urinalysis
– Blood pressure checks
– Dental and oral exams under light anesthesia, if needed
– Imaging (X-rays or ultrasound) if something concerning is found
Regular visits allow your vet to track subtle changes over time and catch potential tumors or systemic diseases at an earlier, more manageable stage.
—
E. General Tumor Prevention & Wellness Support
No strategy can guarantee that your Maltese will never develop cancer, but overall wellness can support the body’s resilience and may lower some risk factors.
1. Maintain a Healthy Weight
– Use measured meals rather than free-feeding.
– Adjust food amounts if weight gain or loss is noticed.
– Monitor body condition monthly by sight and touch.
Healthy weight reduces chronic inflammation and strain on the body, which is beneficial for overall disease resistance.
2. Diet and Hydration
– Feed a complete, balanced diet appropriate for your dog’s age, size, and health status.
– Encourage fresh water availability at all times.
– Limit highly processed treats; choose simple, vet-approved options.
Some owners are interested in home-cooked or specialized diets. These can be considered, but should be formulated with veterinary guidance (ideally a board-certified veterinary nutritionist) to avoid deficiencies or imbalances.
3. Regular Physical Activity
– Keep your Maltese moderately active daily.
– Combine short walks with indoor games to avoid overexertion.
– Mental stimulation (training, puzzle feeders) can also promote overall health.
4. Sun and Environmental Risk Management
– Limit long, direct sun exposure, especially mid-day, for white-coated dogs.
– Protect pink or lightly pigmented areas (ears, nose, belly) by:
– Avoiding sunbathing during peak hours
– Asking your vet about pet-safe sun protection for specific situations
– Avoid tobacco smoke and strong chemical fumes in the home whenever possible.
5. Thoughtful Use of Supplements and Integrative Support
Many owners explore supplements such as:
– Omega-3 fatty acids
– Certain antioxidant blends
– Joint-support supplements
– Herbal formulas for general wellness
These may support skin, joint, and immune health, but they are not substitutes for medical treatment and have not been proven to cure or reverse cancer. Always:
– Discuss any supplement with your veterinarian first
– Mention all products your dog receives to avoid interactions with medications
—
F. Optional Integrative Care: Complementing, Not Replacing, Veterinary Treatment
Some families are interested in holistic or traditional approaches to support their Maltese, especially if cancer is diagnosed or strongly suspected. Integrative care may include:
– Acupuncture to support comfort and mobility
– Massage or gentle bodywork to reduce tension and improve relaxation
– Herbal or TCM-inspired formulas aimed at supporting vitality and balance
– Stress-reduction strategies, such as routine, calm environments, and gentle handling
These methods can sometimes help with quality of life, comfort, and overall resilience, but:
– They should always be coordinated with your primary veterinarian or a veterinary oncologist.
– They should never replace recommended diagnostics or treatments, such as surgery, radiation, or chemotherapy when those are advised.
Working with a vet experienced in integrative medicine can help you safely combine conventional and supportive care.

Conclusion
Maltese are long-lived, affectionate companions, and with longer life comes an increased chance of tumors and cancers—especially skin masses, mammary tumors in intact females, and age-related cancers like lymphoma. By watching closely for early changes, from new lumps to subtle shifts in appetite or energy, you give your dog the best chance of timely diagnosis and effective care. Partnering with your veterinarian for regular senior checkups, smart prevention, and individualized monitoring is the most powerful way to safeguard your Maltese’s health throughout their golden years.
by TCMVET | Dec 15, 2025 | Dog Cancer & Tumors
Maltese cancer risks, early tumor symptoms in Maltese dogs, common cancers in this breed—these are concerns many caring owners don’t think about until their small, white companion becomes a senior. Understanding how this particular breed ages, and what kinds of tumors they are more prone to, can help you catch problems sooner and support your dog’s health for as long as possible.
—
A. Breed Overview: The Maltese at a Glance
The Maltese is a toy breed known for its long, silky white coat, bright personality, and strong attachment to their family. Typically weighing 4–7 pounds (though some are a bit larger) and standing under 10 inches tall, they are small but often surprisingly bold and confident.
Temperament and lifestyle:
– Affectionate, people-oriented, and often “velcro dogs”
– Generally good apartment pets and thrive indoors
– Enjoy short walks and play sessions more than intense sports
– Can be prone to separation anxiety if left alone frequently
Typical lifespan:
Maltese often live into their early to mid-teens, with many reaching 13–15 years or more with good care. This long lifespan means they spend a significant portion of their life as seniors—when tumor and cancer risks naturally increase.
Breed-related health tendencies:
– Dental disease and oral issues are very common
– Luxating patellas (loose kneecaps)
– Heart disease (especially in older dogs)
– Eye issues (tear staining, cataracts with age)
– Skin issues and allergies in some lines
While the Maltese is not at the very top of the list for cancer-prone breeds like Boxers or Golden Retrievers, small companion dogs, including Maltese, do commonly develop certain tumors as they age—especially skin masses, mammary tumors (in intact females), and oral growths. Because of their long lives, they simply have more years in which cancer can develop.
—
B. Tumor and Cancer Risks for Maltese Dogs
1. Skin Tumors (Benign and Malignant)
Skin masses are among the most frequently noticed problems in older Maltese. Their white coat and thin skin make lumps easier to feel but sometimes harder to see.
Common skin or subcutaneous (under the skin) masses may include:
– Benign growths such as lipomas (fatty tumors), sebaceous adenomas, or warts
– Malignant tumors like mast cell tumors or soft tissue sarcomas
Why they’re a concern in Maltese:
– Their small body size means even small tumors can interfere with movement or comfort.
– White, light-skinned dogs may be more sensitive to sun exposure, which can play a role in some skin changes over time.
Any new lump or bump on a Maltese—no matter how small—should be checked by a veterinarian rather than “watched” indefinitely.
2. Mammary Tumors (Primarily in Intact Females)
Unspayed female Maltese, especially those that were not spayed before their first or second heat cycle, can be at higher risk for mammary (breast) tumors later in life. These can range from benign to highly malignant.
Factors that influence risk:
– Reproductive history: Early spaying dramatically reduces the risk of mammary cancer.
– Age: Risk increases sharply after about 7–8 years in intact females.
– Hormones: Repeated heat cycles and hormonal fluctuations can contribute to mammary tissue changes.
Owners of older intact female Maltese should regularly feel along the mammary chains (the two lines of nipples from chest to groin) for small, firm nodules or lumps.
3. Oral Tumors and Dental-Related Masses
Maltese are very prone to dental disease due to:
– Small mouths with crowded teeth
– Tendency for tartar build-up and gum problems
Chronic inflammation in the mouth can sometimes be associated with oral growths. These may include:
– Benign epulides (gum growths)
– Malignant oral tumors such as melanomas, squamous cell carcinomas, or fibrosarcomas
Because these dogs often need dental cleanings, oral exams under anesthesia are an important chance to spot early lesions.
4. Lymphoma and Other Internal Cancers
While not uniquely common to the Maltese, lymphoma (cancer of the lymphatic system) and tumors of internal organs (like the spleen, liver, or digestive tract) can occur.
Risk factors include:
– Age: Most internal cancers are seen in middle-aged to senior dogs.
– Body size and metabolism: Small dogs with long lifespans simply live long enough to be at risk.
Signs are often subtle at first—changes in appetite, mild weight loss, or decreased energy—so owners may mistake them for “just getting old.”
5. Testicular Tumors (Unneutered Males)
Unneutered male Maltese, especially those with undescended testicles (cryptorchidism), may have a higher risk of testicular tumors.
– Cryptorchid testicles often remain in the abdomen or groin and are at higher risk for malignancy.
– Even normally descended testicles can develop tumors with age.
Regular checks of the scrotum and abdomen (for dogs known to have undescended testicles) are important.
—
C. Early Warning Signs Owners Should Watch For
Catching problems early is often one of the most important things you can do for your Maltese. Because they are small and stoic, even modest changes can signal something significant.
Skin and Body Changes
Monitor your dog’s body regularly:
– New lumps or bumps under or on the skin
– Changes in existing lumps, such as:
– Growing quickly
– Becoming firmer or irregular
– Redness, ulceration, or bleeding
– Sores that don’t heal, especially on sun-exposed areas like the nose or ear tips
Helpful habit:
Once a month, gently run your fingers over your Maltese’s entire body while they’re relaxed—during grooming, brushing, or cuddle time. Make a simple note of any new findings and when you first noticed them.
Behavior, Appetite, and Weight
Watch for:
– Gradual or sudden weight loss, even if they are still eating
– Loss of appetite or fussiness about food that is unusual for your dog
– Drinking or urinating more than usual
– Lethargy—wanting to sleep more, shorter walks, or reluctance to play
– Changes in personality, such as irritability or withdrawal
Because Maltese are naturally lively and engaged, a noticeable drop in energy is worth discussing with your veterinarian.
Pain, Mobility, and Comfort
Signs that may be associated with tumors or general illness:
– Stiffness, limping, or hesitating to jump on furniture they previously managed easily
– Crying when picked up or touched in a certain area
– Difficulty climbing stairs or getting comfortable when lying down
While these can also be signs of arthritis, they warrant a vet visit—especially in an older dog.
Breathing, Coughing, and Bleeding
More urgent signs include:
– Persistent coughing or labored breathing
– Nosebleeds or other unexplained bleeding
– Vomiting or diarrhea that doesn’t resolve, especially if there’s blood
– Abdominal swelling or discomfort
These are reasons to seek veterinary attention as soon as possible rather than waiting.
When to Call the Vet Promptly
Contact your veterinarian if:
– A lump is new and present for more than 2 weeks
– Any mass suddenly grows, becomes painful, or starts to bleed or ooze
– Your Maltese has unexplained weight loss, reduced appetite, or noticeable lethargy lasting more than a few days
– You notice oral changes, such as foul odor, drooling, difficulty eating, or visible growths in the mouth
Your vet can decide whether simple monitoring, a needle sample (aspiration), or further testing is appropriate.

D. Senior Care Considerations for Maltese
As Maltese age, their needs change. Thoughtful senior care can help catch tumors earlier and support their overall resilience.
How Aging Affects Maltese
Common age-related changes include:
– Slower metabolism and greater tendency to gain fat and lose muscle
– Increased risk of heart disease, dental disease, and joint problems
– Higher likelihood of tumors developing, even in previously healthy dogs
Because they are long-lived, many Maltese will spend several years in a “senior” or “geriatric” phase.
Nutrition and Body Condition
For older Maltese:
– Aim for a lean, well-muscled body—you should feel ribs easily under a thin layer of fat.
– Discuss appropriate senior or adult diet options with your vet, especially if your dog has heart, kidney, or digestive issues.
– Avoid free-feeding; measured meals twice a day make it easier to spot changes in appetite.
Obesity can stress joints and organs and may complicate both surgery and cancer treatment should tumors occur.
Exercise and Activity
Even small, delicate dogs need movement:
– Short, frequent walks and gentle indoor play are usually ideal.
– Avoid extreme heat or cold; Maltese do best in moderate conditions.
– Mental stimulation (training, puzzle toys, scent games) keeps their mind sharp and can improve overall quality of life.
Adjust exercise if you notice coughing, fatigue, or pain, and mention these signs to your vet.
Joint Care and Pain Awareness
Maltese can suffer from knee problems, arthritis, and spinal issues:
– Watch for subtle lameness or reluctance to jump on beds or couches.
– Soft bedding and non-slip rugs can help prevent slips and falls.
– Pain management—whether through medications, supplements, or physical therapy—should always be discussed and overseen by a veterinarian.
Veterinary Check-Ups and Screening
For senior Maltese (often considered around 8–9 years and older):
– Consider wellness exams every 6 months rather than once a year.
– Ask about:
– Routine bloodwork and urinalysis
– Regular dental exams and cleanings
– Thorough skin and lymph node palpation
– Weight and body condition checks
More frequent visits allow your vet to compare subtle changes over time and pick up issues earlier.
—
E. General Tumor Prevention & Wellness Support
No lifestyle choice can guarantee a dog will never develop cancer, but you can meaningfully support your Maltese’s overall health and potentially reduce some risk factors.
Healthy Weight and Body Condition
Excess weight is linked to many health problems:
– Keep your Maltese at an ideal body condition—lean but not skinny.
– Use a measuring cup for food and limit high-calorie treats.
– Ask your vet what your dog’s target weight should be.
Diet and Hydration
Focus on:
– A complete and balanced diet appropriate for your dog’s age, size, and health conditions
– Easy-to-chew kibble or wet food if dental issues are present
– Clean, fresh water available at all times
Some owners explore diets with high-quality proteins and whole-food ingredients. If you are considering home-cooked or alternative diets, always do so under veterinary guidance to ensure they remain nutritionally complete.
Regular Physical Activity
Consistent, moderate exercise:
– Helps maintain a healthy weight
– Supports muscle mass and joint health
– Promotes good circulation and digestion
For Maltese, this often means:
– Daily short walks
– Gentle play sessions
– Occasional short training sessions (which also provide mental exercise)
Environmental Considerations
While not all environmental cancer risks are fully understood in dogs, you can take sensible precautions:
– Limit excessive sun exposure, especially on the nose and lightly pigmented skin.
– Avoid letting your dog walk or play on recently treated lawns or areas sprayed with chemicals until they are dry and considered safe.
– Store household chemicals, rodenticides, and other toxins securely.
Supportive Supplements and Integrative Wellness
Some owners explore:
– Joint-support supplements
– Omega-3 fatty acids for general wellness
– Antioxidant-rich diets or supplements
These may support overall health but are not proven to prevent or cure cancer. Always discuss any supplement, herb, or new wellness product with your veterinarian before starting it, especially if your dog is on other medications.
—
F. Optional Integrative Care: Complementing Conventional Veterinary Medicine
If your Maltese is diagnosed with a tumor or cancer, some families consider integrative or holistic approaches alongside conventional care.
Examples of supportive strategies (under veterinary guidance) can include:
– Acupuncture to support comfort and mobility
– Gentle physical therapy or massage to maintain function and reduce stiffness
– Mindful, balanced nutrition designed to support overall vitality
– Stress-reduction measures like a consistent routine, quiet resting areas, and gentle handling
These approaches aim to support quality of life, comfort, and resilience, not to replace surgery, chemotherapy, or other oncologist-recommended treatments. Any integrative care plan should be coordinated with your primary veterinarian or a veterinary oncologist so that all treatments work together safely.
—
Conclusion
Maltese cancer risks increase as these small, long-lived dogs reach their senior years, with skin masses, mammary tumors in intact females, dental- and oral-related growths, and internal cancers all possible. By watching for early tumor symptoms in Maltese dogs—such as new lumps, changes in appetite, weight loss, or shifts in energy—you can seek veterinary evaluation before problems progress. Regular wellness exams, careful senior care, and thoughtful lifestyle choices tailored to this breed can make a meaningful difference in early detection and overall well-being. Working closely with your veterinarian throughout your Maltese’s life is the best way to monitor common cancers in this breed and support your companion through every life stage.
