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:
– 尺寸： 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 良性 to highly malignant.
– Risk increases with age 和 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
– 鱗狀細胞癌
– 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
– 不明原因的體重減輕, 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
– 持續咳嗽 or trouble breathing
– 流鼻血 or bleeding from the mouth
– Bloody urine, straining to urinate, or frequent accidents
– 嘔吐或腹瀉 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
– 心臟病 (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 脂肪酸
– 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:
– 針刺 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.

結論
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.
