Greyhound Health Issues to Plan For

Why greyhounds carry breed-specific health risks

Greyhounds are one of the oldest dog breeds in the world and have been selectively bred for athletic performance for centuries. That long history of selection has concentrated certain genetic patterns, including some that cause health issues. The modern racing industry has further concentrated specific lines that perform on the track.

Two other factors specific to ex-racing greyhounds:

• Racing wear and tear. Many ex-racers retire with old injuries (toe injuries, hock issues, soft tissue strains) that affect their joints in later life. Most are mild and manageable; some develop into arthritis.
• Kennel diet history. The high-protein racing diet is calorie-dense but not optimised for long-term dental health. Most ex-racers arrive with significant dental disease at adoption.

The most authoritative sources on greyhound-specific health are the Australian Veterinary Association, the RSPCA Knowledgebase and the GAP NSW health information for adopted greyhounds.

1. Osteosarcoma (bone cancer)

Osteosarcoma is the most serious greyhound-specific health risk. The rate in greyhounds is 4 to 7 times higher than in the general dog population. It is the leading cause of death in greyhounds that survive past middle age and accounts for many of the earlier deaths in the breed.

Where it strikes:

Osteosarcoma usually affects the long bones of the legs: typically the radius (front leg, near the wrist), the humerus (front leg, near the shoulder), the femur (back leg, near the hip), or the tibia (back leg, below the knee). Less commonly it affects the jaw, ribs or pelvis.

Early signs:

• Unexplained lameness in a leg that does not resolve within 48 hours
• Swelling near a joint
• Reluctance to bear weight on a leg
• Sudden severe lameness without obvious injury
• Reduced activity or appetite

Any of these in an adult greyhound warrants a vet visit that week. The cardinal rule: persistent lameness without obvious cause in an adult greyhound is osteosarcoma until proven otherwise.

Diagnosis and treatment:

Initial diagnosis is by X-ray. If suspicious findings appear, the vet refers to an oncologist for further imaging and biopsy. Treatment depends on stage and location:

• Amputation plus chemotherapy. The gold standard for limb osteosarcoma. Amputation removes the source of pain and the cancer locally; chemotherapy addresses microscopic spread. Median survival with this combination is 10 to 12 months; some dogs live 2+ years.
• Palliative care. Pain management, anti-inflammatory medication, sometimes radiation for pain relief. Median survival without surgery is 1 to 3 months.
• Limb-sparing surgery. Available at specialty centres for select cases. Costs significantly more than amputation.

Cost in Sydney:

• Initial workup (X-rays, blood, biopsy): $1,500 to $3,000
• Amputation surgery: $4,000 to $7,000
• Full chemotherapy course (typically 4-6 cycles): $5,000 to $10,000
• Palliative pain management ongoing: $200 to $600 per month

2. Anaesthesia sensitivity

Greyhounds metabolise many common anaesthetic drugs differently from other breeds. This is largely due to lean body composition (very little fat to act as a drug reservoir), a unique liver enzyme profile, and increased sensitivity to certain drug classes. Standard dosing calculated by weight can be too high or too long-acting, with potentially serious complications.

The practical reality:

• Mention the breed every time. At every vet visit involving sedation or anaesthesia, remind the staff your dog is a greyhound and ask whether the protocol is sighthound-appropriate.
• Use a vet experienced with greyhounds. Sydney has several vets and specialty practices with extensive greyhound experience. Ask your rescue or your local greyhound community for referrals.
• For non-urgent procedures, the dental clean is the test. If your vet handles a greyhound dental clean confidently and you trust their anaesthetic protocol, you have found a reliable vet for the breed.
• For complex procedures (orthopaedic surgery, oncology), use a specialty hospital. SASH, Animal Referral Hospital and similar Sydney specialty centres routinely handle greyhounds.

The drugs of concern are mostly older barbiturates and certain induction agents. Modern protocols using propofol, alfaxalone or ketamine-based inductions with careful titration are generally safe. Acepromazine (a common pre-anaesthetic sedative) has known greyhound sensitivity and is typically avoided or used at lower doses.

3. Gastric Dilation Volvulus (bloat)

Bloat is when the stomach fills with gas and then twists on its axis (volvulus), cutting off blood supply to the stomach and spleen. It is a true veterinary emergency; dogs can die within hours without surgery. Deep-chested breeds including greyhounds are at higher than average risk.

Signs to recognise immediately:

• Distended belly that comes on rapidly (often within 30 minutes)
• Unproductive retching (heaving as if to vomit but nothing comes up)
• Excessive drooling
• Restlessness, pacing, inability to settle
• Pale gums, fast breathing, weakness in later stages

If you see these signs together, drive immediately to a 24-hour vet. Do not wait. Survival rates with prompt emergency surgery are good; survival rates without are near zero.

Risk reduction:

• Two or three smaller meals daily rather than one large one
• Slow-feeder bowl to reduce gulping and air swallowing
• Avoid vigorous exercise for one hour before and after meals
• Do not let the dog gulp large amounts of water immediately after exercise
• Some vets recommend prophylactic gastropexy at the time of desexing. This is a surgical procedure that tacks the stomach to the abdominal wall to prevent twisting. Not universally recommended; discuss with your vet whether it suits your specific dog.
• The raised feeder debate. Older advice recommended raised feeders to reduce bloat; more recent evidence suggests they may actually increase risk. Confirm current best practice with your vet.

4. Severe dental disease

Severe dental disease is nearly universal in ex-racing greyhounds at the time of adoption. The combination of racing diet (high protein, no chewing-action), kennel feeding patterns and lack of routine dental care leaves most retired racers with significant tartar buildup, gum disease and often loose or rotting teeth.

Reputable rehoming programs (GAP NSW, Greyhound Rescue, Friends of the Hound) include a full dental clean and any necessary extractions before adoption. The dog arrives with a clean baseline. Maintaining that baseline is the lifelong project.

Ongoing dental care:

• Daily tooth brushing with dog-safe toothpaste. The single most effective home intervention. Most greyhounds tolerate it well with patient introduction.
• Dental chews and prescription dental diets reduce plaque accumulation between cleanings.
• Annual dental check at the vet. Quick visual exam to catch problems early.
• Professional dental cleaning every 1-2 years under anaesthetic. Costs $800 to $1,800 in Sydney depending on extractions needed.
• Watch for warning signs: bad breath, reluctance to eat hard food, pawing at the mouth, blood on chew toys, visible tartar or red gums.

Untreated dental disease in greyhounds contributes to heart disease, kidney disease and systemic inflammation. It is not a cosmetic issue.

5. Hypothyroidism

Hypothyroidism (underactive thyroid) is more common in greyhounds than in many breeds. The condition causes a sluggish metabolism and a range of symptoms that can be mistaken for normal aging.

Signs:

• Weight gain despite normal or reduced appetite
• Lethargy and reduced enthusiasm for activities
• Thinning or dry coat, sometimes with bald patches
• Skin infections that keep coming back
• Slower heart rate
• Cold intolerance (worse than the normal greyhound cold sensitivity)

Important note: greyhound normal thyroid hormone levels run lower than in most breeds. A vet unfamiliar with the breed may diagnose hypothyroidism in a healthy greyhound based on standard reference ranges. Conversely, a greyhound with genuine hypothyroidism may appear normal on a single test. Full thyroid panels (free T4 by equilibrium dialysis plus TSH) interpreted in the context of greyhound-specific reference ranges are the gold standard. Treatment is daily oral thyroxine, which is inexpensive and well-tolerated.

6. Paw pad corns

Corns are thickened, painful lesions on the paw pads that cause a distinctive head-bob limp. They are unusually common in greyhounds (and rare in most other breeds), thought to be related to the breed's paw structure and possibly to viral causes.

Signs:

• Sudden onset limp without obvious injury
• Visible thickened white or yellow spot on a paw pad (usually a middle pad on a front foot)
• Worse on hard surfaces (footpath, tile) than soft surfaces (grass, carpet)
• Some dogs lick or chew at the affected paw

Treatment options:

• Hulling. Manual removal of the corn by a vet experienced with the procedure. Quick relief but the corn often regrows weeks or months later.
• Surgical excision. Removing the corn surgically, sometimes with skin grafting. Higher up-front cost but more permanent.
• Pad protection. Specialty greyhound boots, pad gel inserts and similar products reduce pressure on the affected pad and slow regrowth.
• Topical treatments. Various pastes, gels and home remedies have variable effectiveness; ask your vet what they specifically recommend.

Sydney has several vets and specialty mobile services experienced with greyhound corns. Ask your rescue or local greyhound community for referrals.

7. Paralysis tick (Sydney-specific risk)

Paralysis tick (Ixodes holocyclus) is a year-round risk along the NSW east coast including Sydney, particularly in bushland, coastal scrub and even some suburban gardens. The tick's neurotoxin causes progressive paralysis and can kill a dog within days if untreated.

Risk reduction:

• Year-round tick prevention. Modern oral preventatives (Nexgard, Bravecto, Simparica) kill paralysis ticks within hours of attachment. Monthly or three-monthly options. Not optional in Sydney.
• Daily tick searches if your dog walks in bushland or coastal areas. Run your fingers thoroughly through the coat, particularly around the head, ears, neck and chest.
• Avoid high-risk areas during peak season (spring through autumn, though Sydney has year-round risk). Bushland off-leash walks carry higher risk than urban park walks.

Signs of paralysis tick:

• Weakness in the back legs, progressing to inability to stand
• Change in bark or voice
• Reluctance to eat or drink (early sign before paralysis)
• Vomiting
• Breathing difficulty (late sign, very serious)

Any of these warrants an immediate vet visit. Treatment involves tick removal, antitoxin and supportive care; the earlier it starts, the better the outcome.

The Sydney pet insurance math for greyhounds

The case for pet insurance is unusually strong for greyhounds. The conditions the breed faces are exactly the type insurance covers well: expensive, sometimes urgent, often requiring specialist care.

A typical Sydney greyhound that needs an osteosarcoma workup and treatment, one dental cleaning, and ongoing tick prevention plus routine care over a 10-year lifespan racks up vet bills of $15,000 to $30,000+. Full pet insurance over the same period costs roughly $9,000 to $14,000 in premiums. The payout-to-premium ratio for greyhounds is one of the strongest of any breed.

Key principles:

• Get coverage before any condition appears. Adopt on Tuesday, sign up Wednesday. All Australian insurers exclude pre-existing conditions.
• High annual limit (at least $20,000) to cover oncology, orthopaedic surgery and emergency hospitalisation.
• Full accident and illness cover. Accident-only is not sufficient for the breed.
• Watch the excess and reimbursement. $200 excess plus 80% reimbursement is reasonable.
• Read the dental coverage carefully. Some insurers exclude dental disease unless caused by accident. For a greyhound that comes with severe pre-existing dental disease, this matters.

Major Australian providers include Bow Wow Meow, PetSure, Petplan and RSPCA Pet Insurance. The Australian Veterinary Association pet insurance guide covers what to look for in a policy.

Sydney vets and specialty hospitals to know

For breed-related conditions, you may eventually need referral to a veterinary specialist. The main referral hospitals serving Sydney greyhound owners:

• Small Animal Specialist Hospital (SASH). Sites at North Ryde and Tuggerah. Full-service specialty hospital with oncology, orthopaedics, internal medicine and 24-hour emergency.
• Animal Referral Hospital (ARH). Multi-specialty practice covering Sydney metro.
• Veterinary Specialists of Sydney (VSOS). Internal medicine and cardiology referral.
• Local greyhound-experienced GP vets. Your rescue can refer you to vets in your suburb experienced with the breed. The GAP NSW community and Facebook groups for Sydney greyhound owners are useful sources of vet recommendations.

The year-by-year health plan

• Year 1 (post-adoption): Baseline vet visit including weight, dental assessment, joint examination, blood panel. Year-round tick prevention from day one. Pet insurance in place from day one.
• Years 2 to 5: Annual vet check including any limping or skin issues. Dental brushing daily, professional clean if recommended. Body condition score monitoring.
• Years 6 to 9: Twice-yearly vet check from age six. Add senior blood panel including thyroid testing. Any limping investigated within 48 hours (osteosarcoma risk increases with age).
• Years 10+: Quarterly check-ins. Quality of life conversations. Pain management as joint or other issues develop. Mobility support (raised feeders, non-slip surfaces, ramps for the car).
