Maltese cancer risks, early tumor symptoms in Maltese dogs, common cancers in this breed are subjects every Maltese owner should understand as their tiny companion enters middle and senior life. While these cheerful, lively dogs often live long, happy lives, their small size and genetic background can influence which tumors they are more likely to develop and how early you might notice changes. Knowing what to watch for—and when to call your veterinarian—can make a real difference in comfort, quality of life, and treatment options.

A. Breed Overview: The Maltese in a Health Context
The Maltese is a toy breed, usually weighing 4–7 pounds, known for its silky white coat, affectionate temperament, and people-oriented nature. They are typically:
– Friendly and attached to their families
– Moderately active, enjoying play but not demanding heavy exercise
– Long-lived, with many reaching 12–15 years or more
Because they often live into their teens, they spend a significant portion of life as “seniors,” when the risk of tumors and cancer naturally increases.
Current evidence does not place the Maltese among the absolute highest-risk breeds for cancer (like Boxers or Golden Retrievers), but:
– As a small, long-lived breed, they do experience age-related cancers.
– They may be overrepresented in certain skin and mammary tumors, especially if not spayed or neutered.
– Their white coat and delicate skin may be more sensitive to sun damage, which can influence some skin conditions over time.
Understanding these tendencies helps you watch for early warning signs and support your dog proactively.

B. Maltese Cancer Risks, Early Tumor Symptoms in Maltese Dogs, Common Cancers in This Breed
While any dog can develop cancer, some tumor types are seen more often in Maltese or small senior dogs in general. The following are among the more frequently reported concerns:
1. Skin Masses and Mast Cell Tumors
Maltese, like many small breeds, can develop various skin growths as they age. Most are benign (like warts or lipomas), but some may be malignant. A key group are tumores de mastócitos, qual:
– Often appear as small skin lumps or raised bumps
– Can change size, shape, or color over days or weeks
– May be itchy, inflamed, or ulcerated
The white coat of the Maltese can make dark or red spots easier to see, but small masses can still hide in long hair. Regularly feeling through the coat is important to catch changes early.
2. Mammary (Breast) Tumors in Intact Females
Unspayed female Maltese are at significant risk for mammary tumors, similar to other small female dogs. These can be:
– Single or multiple firm nodules along the mammary chain (chest to groin)
– Small pea-sized lumps at first, which can grow larger over time
Spaying a female dog before her first or second heat cycle greatly lowers the risk of mammary cancer, but many Maltese are kept intact for breeding or other reasons, which can increase the likelihood of these tumors later in life.
3. Testicular Tumors in Intact Males
Male Maltese that are not neutered—or that have retained testicles (cryptorchidism)—can develop testicular tumors as seniors. These may present as:
– Enlarged, firm, or uneven testicles
– Feminizing signs (hair loss, enlarged mammary tissue) in some hormone-producing tumors
Toy breeds are slightly more prone to retained testicles, which carry a higher tumor risk if they remain in the abdomen or inguinal canal.
4. Lymphoma (Lymphosarcoma)
Lymphoma is a cancer of lymphoid tissue and is seen across many breeds, including Maltese. It may present with:
– Enlarged lymph nodes (firm “lumps” under the jaw, in front of shoulders, behind knees)
– Lethargy, decreased appetite, or weight loss
– Occasional digestive or breathing signs, depending on location
No strong Maltese-specific genetic link is clearly defined, but older small breeds can certainly be affected.
5. Oral and Dental-Related Tumors
Small breeds like the Maltese often have dental crowding and periodontal disease, which can complicate the detection of oral tumors such as:
– Melanoma
– Squamous cell carcinoma
– Other gum or jaw masses
Because Maltese frequently need dental care, regular oral exams are an opportunity to catch suspicious growths early.
6. Other Age-Related Cancers
As long-lived companions, Maltese can also be diagnosed with other cancers seen in older dogs, such as:
– Hemangiossarcoma (cancer of blood vessel cells, often in spleen or heart)
– Liver or intestinal tumors
These are less “breed-strong” but related more to age and overall dog cancer patterns.

C. Early Warning Signs Owners Should Watch For
Early detection often starts at home. Maltese are small enough that careful hands-on checks can reveal new changes quickly.
Skin and External Signs
Monitor for:
– New lumps or bumps anywhere on the body
– Existing lumps that change in size, shape, color, or texture
– Sores that don’t heal, scabs that keep returning, or areas your dog keeps licking or chewing
– Discoloration or crusting on ear tips, nose, or lightly pigmented skin (especially in sun-exposed dogs)
Tip: Once a month, gently run your hands over your dog from nose to tail, parting the hair to look at the skin. Note anything new or different.
Whole-Body and Behavior Changes
Subtle shifts in behavior or body condition can be early flags:
– Perda de peso despite eating normally, or a drop in appetite
– Increased tiredness or reluctance to play or go for walks
– Limping or stiffness that doesn’t resolve with rest
– New or worsening cough, rapid breathing, or repeated “hacking”
– Vomiting, diarrhea, or changes in stool lasting more than a day or two
– Bad breath, drooling, or trouble chewing that’s new for your dog
– Any sangramento inexplicável, especially from the mouth, nose, or rectum
When to See the Veterinarian Promptly
Contact your veterinarian if you notice:
– A lump larger than a pea that lasts more than a month
– Any mass that cresce rapidamente or becomes ulcerated or painful
– Persistent behavior changes (fatigue, hiding, irritability)
– Ongoing weight loss, reduced appetite, or digestive problems
– Breathing difficulties, frequent coughing, or collapse
Your vet may recommend tests such as a physical exam, bloodwork, imaging, or a needle sample/biopsy to determine the nature of a lump. These tests are diagnostic tools, not commitments to major surgery, and can provide clarity and options.

D. Senior Care Considerations for Maltese
Maltese often age gracefully, but by around 7–9 years, many are considered seniors. Aging changes can overlap with or mask tumor signs, so focused care becomes especially important.
Nutrition and Body Condition
Senior Maltese benefit from:
– A balanced, age-appropriate diet tailored to their size and activity level
– Maintaining a lean, but not thin, body condition (you should feel ribs easily but not see them protruding)
– Monitoring for sudden weight loss or gain, which can signal underlying disease
Discuss with your vet whether a senior formula or specific nutrient profile (e.g., joint support, kidney or heart-sensitive diets) is suitable for your dog’s overall health.
Exercise and Activity Adjustments
Regular movement helps support:
– Joint mobility and muscle tone
– Digestive and heart health
– Mental well-being
For older Maltese:
– Favor short, frequent walks over long strenuous outings
– Avoid jumping from high furniture to reduce injury risk
– Incorporate gentle play and brain games rather than intense, high-impact activity
A sudden drop in activity tolerance can be a sign of pain, heart or lung issues, or hidden tumors—worth a vet check.
Joint Care and Pain Management
Small dogs are not immune to arthritis or back problems. As your Maltese ages:
– Watch for difficulty jumping, climbing stairs, or getting comfortable
– Provide soft bedding and non-slip flooring
– Ask your veterinarian about safe pain management options and joint-support strategies (medications, physical therapy, or other modalities)
Never start pain medication or supplements without veterinary guidance; some products can interact with existing conditions or medications.
Weight Control
Extra weight puts stress on joints and can complicate other diseases, including some cancers. To help:
– Measure meals instead of free-feeding
– Limit high-calorie snacks; use small, healthy treats or part of their regular food as rewards
– Re-check your dog’s weight at least every 3–6 months
Veterinary Check-Ups and Screening
For senior Maltese, many veterinarians recommend:
– Wellness exams every 6 months, rather than once a year
– Periodic bloodwork and urine tests to screen for organ changes
– Regular oral exams and dental cleanings to monitor the mouth for both disease and tumors
– Discussion of any new lumps; many can be quickly evaluated with a fine needle sample
Building a long-term relationship with your vet helps them notice subtle changes over time, which is especially valuable for early cancer detection.

E. General Tumor Prevention & Wellness Support
No approach can guarantee a dog will never develop cancer, but several lifestyle factors may reduce risk or support the body’s resilience.
Healthy Weight and Balanced Diet
– Keep your Maltese at a lean, healthy weight through appropriate portions and activity.
– Choose a complete, balanced diet (commercial or carefully designed home-prepared under veterinary guidance).
– Ensure clean, fresh water is always available.
Regular Physical Activity
Consistent moderate exercise helps:
– Maintain muscle and joint health
– Support immune function and circulation
– Reduce stress and boredom
For a Maltese, this might mean short walks, gentle play sessions, and interactive toys rather than intense running.
Minimizing Environmental Risks
Where reasonable:
– Limit prolonged sun exposure on bright days, especially for sun-sensitive white skin and noses; shaded walks and indoor play can help.
– Avoid excessive exposure to cigarette smoke, harsh cleaning chemicals, or unnecessary lawn chemicals.
– Use only dog-safe flea, tick, and household products as recommended by your veterinarian.
Thoughtful Use of Supplements and “Natural” Supports
Some owners explore:
– Omega-3 fatty acids
– Joint-support supplements
– Antioxidant-rich foods or formulas
While these may support overall wellness, they are not proven cures or treatments for cancer. Always:
– Discuss any supplement or herb with your veterinarian first
– Inform your vet about everything your dog takes, to avoid interactions or side effects
– Remember that supportive care complements—never replaces—appropriate veterinary diagnostics and treatment
—
F. Integrative and Holistic Approaches (Optional Support)
Some families consider integrative approaches alongside conventional care, such as:
– Acupuncture or gentle bodywork to support comfort and mobility
– Traditional wellness frameworks (such as TCM-inspired concepts of balancing the body and supporting vitality)
– Stress-reduction methods like massage, calming environments, and routine
When guided by a veterinarian or qualified integrative practitioner, these methods may help with comfort, stress, and quality of life. They should always:
– Be used in addition to, not instead of, recommended diagnostics and treatments
– Be tailored to the individual dog’s health status
– Avoid any claim of curing or shrinking tumors
