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’s health, especially as they age. While this toy breed is generally long-lived and sturdy for its size, they are not immune to tumors and cancer, and some problems are more likely to appear in later life. Understanding what to watch for—and how to support your dog’s wellbeing over the long term—can make a real difference in detecting issues early.

A. Breed Overview: The Maltese at a Glance
The Maltese is a small toy breed, usually weighing 4–7 pounds, known for its long, silky white coat and affectionate, people-focused personality. They are typically:
– Gentle, loving, and highly attached to their family
– Alert and sometimes vocal, making them good little watchdogs
– Energetic in short bursts but very adaptable to apartment living
With good care, Maltese often live into their mid-teens, around 12–15 years or more. That long lifespan is wonderful—but it also means they spend more years in the “senior” category, when tumors and age-related diseases become more common.
Compared with some large or giant breeds, the Maltese is not considered among the very highest-risk dogs for specific cancers. However, like all breeds, they can develop:
– Skin tumors (both benign and malignant)
– Mammary tumors in intact females
– Oral tumors
– Blood-related cancers such as lymphoma
Their small size, long lifespan, and typical lifestyle (indoor, close to people) can influence how and when certain issues show up.

B. Tumor and Cancer Risks for Maltese Dogs
1. Skin Tumors (Mast Cell Tumors, Benign Lumps, and Others)
Maltese have light-colored, often sensitive skin hidden under a long coat. They can develop:
– Benign growths such as lipomas (fatty tumors) or sebaceous gland tumors
– Malignant tumors such as mast cell tumors or soft-tissue sarcomas
These can appear as:
– Small, pea-sized bumps under or on the skin
– Larger, irregular masses
– Lumps that suddenly grow, change color, or become ulcerated
Because their coat can hide small changes, routine hands-on checks are especially important.
2. Mammary (Breast) Tumors in Intact Females
Unspayed female Maltese, especially those who cycle through multiple heats or have litters, have a higher risk of mammary tumors. These can be:
– Benign (non-spreading)
– Malignant (cancerous, with potential to spread to lungs or other organs)
Risk is heavily influenced by reproductive history. Early spaying (before or shortly after the first heat) can significantly reduce the likelihood of mammary tumors, but decisions about spay timing should always be made with a veterinarian based on the individual dog.
3. Oral Tumors
Small and toy breeds, including Maltese, may have a somewhat higher likelihood of certain oral tumors compared to some other groups. Complicating factors include:
– Crowded teeth in a small mouth
– Tartar buildup and gum disease
– Chronic inflammation in the mouth
Oral tumors can develop on:
– Gums
– Tongue
– Roof of the mouth
– Jaw bones
They may first be noticed as a small bump on the gum, bad breath, or difficulty chewing.
4. Lymphoma (Cancer of the Lymphatic System)
Lymphoma can occur in any breed, and Maltese are no exception. It affects:
– Lymph nodes (often becoming enlarged and firm)
– Internal organs like the spleen, liver, or intestinal tract
Owners may notice:
– Swollen “glands” under the jaw or behind the knees
– Tiredness, weight loss, or digestive changes
The exact cause is often unknown, but immune system function, genetics, and environmental factors may all play a role.
5. Other Internal Cancers
Less commonly discussed but still possible in Maltese are:
– Liver or spleen tumors
– Bladder tumors (which may cause urinary signs)
– Lung tumors (primary or spread from elsewhere)
Because these are hidden inside the body, early signs can be subtle: changes in energy, appetite, breathing, or bathroom habits.

C. Early Warning Signs Owners Should Watch For
Being alert to early tumor symptoms in Maltese dogs can allow faster evaluation and intervention. Focus on changes rather than specific “diagnoses” at home.
1. Skin and Coat Changes
Check your Maltese regularly during grooming:
– New lumps or bumps under the skin
– Changes in size, shape, or texture of existing lumps
– Sores that don’t heal or keep bleeding
– Areas of redness, thickening, or dark pigment changes
A simple monthly “nose-to-tail” massage is a great habit: use your fingertips to gently feel along the head, neck, chest, belly, legs, and tail. Note anything new or different.
2. Weight, Appetite, and Energy
Subtle changes often show up before obvious illness:
– Gradual or sudden weight loss without diet changes
– Eating less, acting picky, or walking away from food
– Drinking more or less than usual
– Sleeping much more, seeming “down,” or reluctant to play
Because Maltese are small, even small amounts of weight loss can be significant. Consider keeping a monthly weight log.
3. Mobility, Pain, and Behavior Changes
Look for:
– Limping or stiffness, especially after rest
– Resistance to being picked up or touched in certain areas
– Hiding more, becoming clingier, or showing irritability
– Difficulty jumping onto furniture or climbing stairs
These may be age-related joint issues—or could signal pain from an internal mass or bone problem. Either way, they warrant a check-up.
4. Mouth, Breathing, and Bathroom Signs
Pay attention to:
– Bad breath that worsens quickly
– Bleeding from the mouth, drooling, or dropping food
– Persistent coughing or noisy breathing
– Straining to urinate or defecate, blood in urine or stool
– Vomiting that doesn’t resolve or frequent diarrhea
Any of these changes, especially if they last more than a few days or are severe, should prompt a call to your veterinarian.
When to Seek Veterinary Attention
Contact your vet promptly if you notice:
– Any new lump that grows, changes, or feels fixed and hard
– Unexplained weight loss or persistent loss of appetite
– Breathing difficulties, collapse, or pale gums
– Ongoing vomiting, diarrhea, or urinary problems
– Sudden behavior changes or obvious pain
Early evaluation does not always mean cancer is present—but if there is a serious problem, catching it sooner often allows more options.

D. Senior Care Considerations for Maltese
As Maltese age, typically around 8–10 years and older, cancer risk naturally increases. Senior care tailored to this breed can help detect issues earlier and support quality of life.
1. Nutrition and Body Condition
Senior Maltese often need:
– A balanced diet appropriate for age, size, and activity
– Careful portion control to avoid excess weight (which stresses joints and organs)
– Enough high-quality protein to maintain muscle mass
Your veterinarian can help determine an ideal body condition score (BCS) and adjust feedings if your dog is too thin or overweight.
2. Exercise and Activity Adjustments
Gentle, regular movement supports:
– Joint health
– Heart and lung function
– Mental wellbeing
For seniors:
– Replace long, intense exercise with multiple short, easy walks
– Allow time for sniffing and exploring at their own pace
– Use non-slip rugs and ramps to reduce falls and jumping stress
Avoid pushing a tired or breathless dog; sudden changes in exercise tolerance should be discussed with your vet.
3. Joint Care and Pain Management
Many older Maltese develop arthritis or back issues due to their small bones and sometimes fragile joints. Signs include:
– Stiffness when getting up
– Hesitation on stairs
– Reduced interest in play
Your veterinarian can recommend appropriate pain control options, lifestyle changes, and possibly supportive therapies. Never give human pain medications without veterinary guidance—they can be dangerous to dogs.
4. Veterinary Check-Ups and Screening
For a senior Maltese, consider:
– Wellness exams every 6 months
– Routine bloodwork, urinalysis, and possibly imaging (X-rays or ultrasound) based on your vet’s advice
– Regular dental checks, as oral health and oral tumors are key concerns
Frequent exams give your vet a chance to notice subtle early signs that may not be obvious at home.

E. General Tumor Prevention & Wellness Support
While no approach can guarantee a dog will avoid tumors or cancer, you can lower certain risk factors and support your Maltese’s overall health.
1. Maintain a Healthy Weight
Extra weight can:
– Increase inflammation in the body
– Put stress on joints and organs
– Make some diseases harder to manage
Weigh your dog regularly, adjust food portions as needed, and use healthy training treats in moderation.
2. Balanced Diet and Hydration
Offer:
– A complete, balanced diet formulated for small dogs and life stage
– Fresh water available at all times
– Limited table scraps, especially high-fat or heavily processed foods
Some owners explore diets with specific ingredients or supplements (such as omega-3 fatty acids, antioxidants, or joint-support nutrients). These may support general health, but they are not cancer cures. Always discuss any diet change or supplement with your veterinarian to ensure safety and appropriate dosing.
3. Regular Physical and Mental Activity
For a Maltese, “exercise” doesn’t mean marathons:
– Short walks, gentle play, and indoor games
– Puzzle feeders, training sessions, and scent games to engage their mind
A mentally and physically active dog tends to have better overall resilience.
4. Environmental Risk Awareness
You can’t control everything, but you can reduce some exposures:
– Avoid secondhand smoke around your dog
– Use pet-safe cleaning products when possible
– Prevent chronic sunburn on lightly pigmented skin (ask your vet about safe options if your Maltese spends time in strong sun with a short-trimmed coat)
– Be cautious with lawn chemicals and pesticides; follow label instructions and keep pets away until treated areas are dry
Again, these steps do not guarantee prevention but may reduce cumulative stress on the body.

F. Integrative and Holistic Support (As a Complement Only)
Some Maltese owners are interested in integrative approaches to help support a dog with tumors or cancer, alongside conventional veterinary care. These may include:
– Acupuncture or gentle bodywork to support comfort and mobility
– Carefully chosen herbal or nutritional supplements aimed at supporting general vitality
– Stress-reduction strategies such as calm environments, predictable routines, and gentle massage
The goal of these approaches is typically to support overall wellbeing, comfort, and resilience—not to replace surgery, chemotherapy, or other veterinary-recommended treatments when those are appropriate.
If you’re considering holistic or traditional wellness options, always:
– Involve your primary veterinarian
– Seek practitioners with formal training in veterinary integrative medicine
– Discuss potential interactions with any existing medications or treatments
