Quick orientation
Arthritis (osteoarthritis) is one of the most common chronic conditions in older UK dogs — affecting an estimated 80% of dogs over the age of eight, and many earlier than that. It progresses slowly, the early signs are easy to miss, and dogs are extraordinarily good at hiding pain. The good news: with early diagnosis and consistent management, most arthritic dogs continue to enjoy good quality of life for years.
What arthritis actually is
Osteoarthritis is a degenerative joint disease where the cartilage cushioning the ends of bones gradually breaks down. As cartilage thins, the underlying bone becomes inflamed, the joint capsule thickens, and movement becomes increasingly painful. It is a slow, progressive condition rather than a sudden injury, which is part of why it is so often missed in the early stages.
Most commonly affected joints in dogs are the hips, elbows, knees (stifles), shoulders, and the spine. Larger breeds and breeds with known orthopaedic predispositions (Labradors, German Shepherds, Rottweilers, Bernese Mountain Dogs, French Bulldogs) tend to develop arthritis earlier and more severely, but no breed is immune. Excess body weight is the single biggest modifiable risk factor across all breeds.
There is no cure for canine arthritis. The aim of treatment is to slow progression, manage pain, and preserve mobility — and modern UK veterinary practice has a strong toolkit for doing exactly that.

Warning signs to watch for
The earliest signs are subtle and easy to mistake for "just getting older":
- Stiffness after rest — slow to get up from a lie-down, especially first thing in the morning or after a nap.
- Reluctance with stairs, jumping, or car-boots — hesitating before what used to be effortless.
- Slowing down on walks — needing more breaks, walking shorter distances, or seeming reluctant to go in the first place.
- Visible limp, especially after exercise. Limps that worsen with cold or damp weather are particularly suggestive.
- Behaviour changes — a previously active or social dog becoming withdrawn, irritable, or sleeping more.
- Reduced grooming in dogs that previously kept themselves clean (bending may have become uncomfortable).
- Muscle wastage over the back legs or hips — a sign of chronic disuse.
- Reluctance to be touched in specific areas, or a flinch when a particular joint is handled.
If you notice any of these in a dog over six or seven, book a vet check rather than waiting for the next routine appointment. Earlier intervention preserves more mobility.
What diagnosis involves
Most UK general practices can diagnose and stage arthritis in-house. A typical workup includes:
- Clinical examination — the vet will watch your dog walk, manipulate each joint to assess pain and range of motion, and feel for swelling, crepitus (a grating sensation), and muscle wastage.
- Pain scoring — increasingly UK practices use validated tools like the Liverpool Osteoarthritis in Dogs (LOAD) questionnaire (often completed by the owner) to track progression objectively over time.
- X-rays — confirm the diagnosis, identify which joints are affected, and rule out other causes of lameness. Usually performed under sedation. A typical UK package of bilateral hip and stifle X-rays runs in the region of £300–£500 including sedation.
- Blood work — not arthritis-specific, but commonly run for older patients before starting long-term medication, to confirm liver and kidney function are adequate.
- In some cases, referral to a veterinary orthopaedic specialist for advanced imaging (CT or MRI) or assessment for surgical options. Most general-practice arthritis cases never need this.
Ask for a written cost estimate before any non-emergency procedure — something the upcoming CMA transparency reforms will make standard from December 2026, but is good practice now.
Treatment and management
Arthritis is managed across four main pillars, used in combination:
1. Weight management
The single most effective intervention. Even a 10–15% reduction in body weight in an overweight arthritic dog can produce a noticeable reduction in lameness. Many UK practices run free nurse-led weight clinics; ask whether yours does.
2. Exercise modification
Stop the activities that cause flare-ups (off-lead galloping, ball-chasing, jumping). Replace with steady, controlled walks at a consistent pace, ideally on soft surfaces. Hydrotherapy is exceptional for arthritis — swimming and underwater treadmill work build muscle and improve range of motion without joint loading. Many UK regions have dedicated canine hydrotherapy centres.
3. Medication
The mainstay is long-term anti-inflammatory pain relief, typically a non-steroidal anti-inflammatory drug (NSAID) prescribed at the lowest effective dose. Newer monoclonal antibody injections (such as bedinvetmab, marketed as Librela) have been a meaningful addition for many dogs in recent years — a once-monthly injection that can replace or reduce the need for daily oral medication. Discuss what fits your dog's individual case with your vet.
4. Adjuncts and supplements
Omega-3 fatty acids (high-EPA fish oil), green-lipped mussel extract, and prescription joint diets all have varying evidence behind them and can be useful complements to the above. Acupuncture, laser therapy, and physiotherapy are offered by some UK practices and have growing supporting evidence.
Most arthritic dogs do well with a tailored combination of all four, reviewed and adjusted every 3–6 months.
On long-term NSAID use
Long-term NSAIDs are widely used in UK veterinary practice and are generally well tolerated, but they require monitoring. Most vets recommend periodic blood tests (typically every 6–12 months) to check liver and kidney function. Any unexplained vomiting, loss of appetite, or change in drinking habits while on an NSAID should be reported to your vet promptly.
What this typically costs
UK 2026 ballpark figures (will vary by region and practice):
- Initial consultation + clinical exam: £35–£70
- Diagnostic X-rays under sedation (e.g. hips + stifles): £300–£500
- Pre-anaesthetic blood tests: £50–£120
- Ongoing NSAID prescription (varies by dog size): £25–£80/month
- Monthly monoclonal antibody injection (Librela or equivalent, varies by dog size): £50–£150/month
- Hydrotherapy session: £25–£45 per session
- Annual review and repeat bloods: £100–£200
Most lifetime pet insurance policies cover arthritis as a long-term condition, but the cover varies significantly. Check whether your policy has annual or per-condition caps, whether it covers the newer biologic injections, and whether it requires regular wellness checks to honour ongoing claims.

Choosing a vet who handles arthritis well
Most UK general practices are competent at managing arthritis. For more complex cases (early-onset, multiple joints, breed-specific orthopaedic concerns) some things to look for:
- A vet (or nurse) with additional qualifications in pain management or rehabilitation — some hold the International Veterinary Academy of Pain Management certification.
- A practice with a relationship with a local hydrotherapy centre or in-house facility.
- A clear approach to long-term monitoring — ideally regular pain scoring rather than just intermittent re-examinations.
- Willingness to discuss the full medication landscape (including newer injectables) rather than defaulting to one approach.
