A. Borzoi Breed Overview
Graceful, calm, and quietly affectionate, the Borzoi (also called the Russian Wolfhound) is a large sighthound originally bred for speed and hunting. Adults typically weigh 60–105 pounds, with a tall, narrow frame and a long, silky coat. They are generally gentle in the home, often reserved with strangers, and known for their combination of sensitivity and independence.
Average life expectancy ranges from about 9–12 years, which is typical for large breeds. Like many big, deep-chested dogs, Borzois can face specific health issues, including heart disease, bloat (gastric dilatation-volvulus), and musculoskeletal problems. Evidence and breeder reports also suggest they may have an increased tendency toward certain cancers, particularly bone tumors and some internal malignancies, compared with smaller breeds.
While not every Borzoi will develop cancer, their size, body structure, and genetic background mean owners should be especially proactive about monitoring for tumors as they age.

B. Tumor and Cancer Risks for Borzois
Common cancers in this breed
Several tumor types tend to be seen more often in Borzois and similar large sighthounds:
1. Osteosarcoma (bone cancer)
Large and giant breeds are disproportionately affected by osteosarcoma, a malignant tumor of the bone. In Borzois, this often appears in the long bones of the legs (especially near the shoulder, wrist, or knee), but it can occur in other bones as well.
Risk factors that may contribute:
– Body size and limb length: Tall, fast-growing bones seem more vulnerable.
– Genetic predisposition: Certain bloodlines in large breeds show higher incidence.
– Age: Most often seen in middle-aged to older dogs, though it can occur earlier.
2. Hemangiosarcoma
This is an aggressive cancer of blood vessel cells, often affecting the spleen, liver, heart, or skin. It may grow silently inside the body until it ruptures, causing sudden internal bleeding.
Factors that play a role:
– Breed tendency: Deep-chested and larger breeds appear more at risk.
– Age: More common in older dogs.
– Color and coat: Some data in other breeds suggest a link with darker skin areas, but this is not fully clear for Borzois.
3. Lymphoma
Lymphoma affects lymphocytes (a type of white blood cell) and can involve lymph nodes, internal organs, or even the skin.
Possible influences:
– Immune system function: Any underlying immune dysregulation may increase risk.
– Environment: Exposure to certain chemicals or smoke may play a role, as in other breeds.
4. Soft tissue sarcomas
These tumors arise from connective tissues in the skin and under the skin (muscle, fat, fibrous tissue). They can appear as firm lumps that slowly grow over time.
Contributing factors:
– Size and frame: Large breeds may be more prone to some sarcomas.
– Previous trauma or injection sites: Some sarcomas may occur in areas of chronic irritation or prior injury.
5. Testicular and mammary tumors
Reproductive status plays a role:
– Intact males may develop testicular tumors later in life.
– Intact females have a significantly higher risk of mammary (breast) tumors compared to those spayed before or shortly after their first heat.
Why Borzois may be more vulnerable
Several breed traits influence their cancer profile:
– Large, lean body: Big bones and a deep chest are linked with certain cancers like osteosarcoma and hemangiosarcoma.
– Genetic background: As a relatively less common breed, specific genetic issues can concentrate within family lines.
– Typical lifestyle: Active running, sprinting, and high-speed play are normal for Borzois, and though exercise is healthy, repeated micro-injuries or heavy stress on long bones might overlap with tumor risk in predisposed dogs.
Understanding these patterns helps you stay alert without assuming your individual dog will develop the same problems.

C. Early Warning Signs Owners Should Watch For
Cancers can look very different from dog to dog. The most important thing is to know what’s normal for your Borzoi, then notice changes early.
Skin and body lumps
Monitor for:
– New lumps or bumps under the skin
– Existing lumps that grow quickly, change shape, or become firm, ulcerated, or painful
– Swelling on a leg, over a rib, or around a joint
At-home tip:
– Monthly “nose-to-tail” check: Run your hands gently over your Borzoi when they’re relaxed. Note size, location, and feel of any lumps. Take photos with a coin or ruler next to them for comparison.
Bone pain and mobility changes
Bone tumors often cause:
– Lameness or limping that doesn’t resolve with rest
– Reluctance to jump, climb stairs, or run
– Localized pain or sensitivity when you touch a leg
– Swelling or a hard “thickening” over a bone
Any persistent or worsening lameness in a middle-aged or older Borzoi deserves prompt veterinary attention, especially if rest and a few quiet days don’t help.
General behavior and appetite changes
Pay attention to:
– Decreased appetite or picky eating
– Unexplained weight loss, despite normal food portions
– Increased sleeping, reduced interest in walks or play
– Subtle withdrawal, irritability, or restlessness
These signs are not specific to cancer, but they indicate something is wrong and should trigger a veterinary visit.
Internal or sudden symptoms
Internal tumors like hemangiosarcoma can be tricky. Watch for:
– Sudden weakness or collapse
– Pale gums
– Rapid breathing or heart rate
– Distended abdomen or signs of abdominal discomfort
– Episodes of seeming “off,” then returning to normal
These are emergencies—seek veterinary care immediately.
When to see the vet promptly
Contact your veterinarian if you notice:
– Any new lump that persists more than 1–2 weeks
– A lump that doubles in size over a month or less
– Lameness lasting more than a few days, or severe pain
– Ongoing weight loss, loss of appetite, or chronic vomiting/diarrhea
– Coughing, difficulty breathing, or unexplained bleeding
Early evaluation does not mean something is definitely cancerous; it simply improves the chance of prompt diagnosis and better options if a tumor is found.

D. Senior Care Considerations for Borzois
As Borzois age, their long limbs, deep chests, and lean bodies can make them more vulnerable to arthritis, heart issues, and tumors. Many enter their “senior” stage around 7–8 years old.
Nutrition and body condition
Keeping a senior Borzoi at a lean, muscular weight is one of the most powerful ways to support health.
– Avoid obesity: Extra weight strains joints and may increase systemic inflammation, which is linked broadly with disease risk.
– Adequate protein: Older dogs often need high-quality protein to maintain muscle mass.
– Digestive sensitivity: Some seniors do better with easily digestible diets and controlled fat content.
Work with your veterinarian to choose an appropriate senior or adult diet and adjust portions based on body condition, not just the bag’s guideline.
Exercise and activity
Older Borzois typically still enjoy movement but may need modifications:
– Regular, moderate walks instead of high-intensity sprints every day
– Controlled off-leash running in safe, enclosed areas
– Non-impact activities (gentle play, sniff walks) to maintain joint range of motion
Watch for signs of overexertion, such as limping after exercise, heavy panting, or reluctance to go out again.
Joint care and pain management
Their long, slender limbs and rapid early growth can set the stage for arthritis later in life.
Support options (always vet-guided) may include:
– Joint-supportive diets or supplements
– Pain-control medications when needed
– Physical therapy, hydrotherapy, or controlled strengthening exercises
– Ramps or rugs to reduce slipping and jumping
Comfortable joints can make activity safer and reduce the chance of confusing pain with more serious causes like bone tumors.
Veterinary check-ups and screening
For senior Borzois, a more frequent health schedule is wise:
– Twice-yearly wellness exams for dogs over about 7–8 years
– Periodic bloodwork and urinalysis to monitor organ function
– Dental checks, heart and lung assessments
– Discussion about any new lumps, behavior changes, or mobility issues
Your veterinarian may also recommend imaging (X-rays, ultrasound) or specific screening tests if they are concerned about possible tumors based on exam findings.

E. General Tumor Prevention & Wellness Support
There is no guaranteed way to prevent cancer, but you can meaningfully support your Borzoi’s overall health and potentially reduce some risks.
Maintain a healthy weight
– Keep a visible waist and an abdominal “tuck.”
– You should feel ribs easily under a thin layer of fat.
– Adjust food and treat intake based on body condition, not just habit.
Lean dogs often live longer and may experience fewer chronic health problems.
Provide an appropriate diet and hydration
– Choose a balanced commercial diet or carefully formulated home-prepared diet under veterinary guidance.
– Ensure constant access to fresh water.
– Avoid frequent, large, single daily meals; multiple smaller meals may be gentler on the stomach and may help reduce bloat risk.
Discuss any special diets (e.g., grain-free, raw, or heavily supplemented) with your vet, especially if your Borzoi has been diagnosed with a tumor.
Regular physical activity
– Daily walks and moderate play support immune function, muscle mass, and mental health.
– Mental enrichment—scent work, trick training, puzzle feeders—reduces stress and keeps seniors sharp.
Balanced, consistent exercise is better than long periods of inactivity followed by intense bursts.
Limit environmental risks where possible
– Avoid chronic exposure to tobacco smoke, heavy pesticides, or lawn chemicals where you can.
– Store household chemicals securely and clean up spills promptly.
– Use dog-safe sunscreen on thinly furred or pale skin areas if your Borzoi spends long periods in strong sun, after consulting your vet.
Thoughtful use of supplements and “natural” support
Owners sometimes explore:
– Omega-3 fatty acids
– Joint-support formulas
– Certain herbal or mushroom-based products
These may support general wellness, but:
– They have not been proven to cure or shrink cancer.
– Quality and dosing vary widely between products.
Always:
– Discuss any supplement or herbal product with your veterinarian or veterinary oncologist first.
– Inform your vet about everything your dog is taking to avoid interactions with medications or anesthesia.

F. Integrative Care and Supportive Approaches (Optional)
Some families choose gentle, complementary approaches alongside conventional veterinary care. These might include:
– Acupuncture or massage for pain and comfort
– Therapeutic exercise or hydrotherapy to maintain mobility
– Holistic frameworks (like Traditional Chinese Medicine–inspired concepts of “balancing” the body) used as a way to guide diet and lifestyle choices
These methods are best viewed as supportive, not curative. They may help with comfort, stress reduction, and overall resilience but should never replace appropriate diagnostics, surgery, chemotherapy, radiation, or other evidence-based treatments recommended by your veterinary team.
If you’re interested in integrative care:
– Seek practitioners who work in collaboration with your primary veterinarian.
– Be wary of any approach that claims to cure cancer or replace standard treatment.
