Dog Arthritis and Joint Pain: Symptoms and Treatment in the UK

Arthritis is one of the most common chronic health conditions in UK dogs, affecting an estimated one in five adult dogs and up to 80% of dogs over the age of eight. Despite its prevalence, it is significantly underdiagnosed — many owners and even some vets attribute early signs to 'just getting old' rather than a treatable painful condition.

Recognising Arthritis in Your Dog

Canine arthritis (osteoarthritis or degenerative joint disease) causes pain, stiffness, and reduced mobility. The signs are often subtle in the early stages and worsen gradually — which is precisely why the condition is so frequently missed until it is advanced. Key signs to watch for include: stiffness after rest, particularly in the morning or after sleeping; reluctance or difficulty rising from lying down; hesitation to climb stairs, jump into the car, or jump onto furniture; a shortened stride or altered gait; reduced enthusiasm for walks — lagging behind, stopping more frequently; and licking or chewing at specific joints.

More obvious signs in advanced disease include visible swelling around joints, muscle wastage (atrophy) in affected limbs, and significant lameness. Behavioural changes — increased irritability, aggression when touched, or becoming more withdrawn — can also indicate chronic pain that has gone unrecognised.

The PDSA's pain assessment tools used in clinical practice recognise that owners are often the first to notice the subtle behavioural changes that indicate joint pain. If you notice any of these signs, particularly in a dog over five years old or a large breed dog, a vet assessment is warranted.

Diagnosis and Why It Matters

Accurate diagnosis of canine arthritis involves a physical orthopaedic examination — your vet will assess gait, range of motion in individual joints, and check for pain, crepitus (grating sensation), and swelling. X-rays are the standard diagnostic imaging tool, revealing characteristic changes such as joint narrowing, bone spurs (osteophytes), and subchondral bone changes.

A definitive diagnosis changes the management approach significantly. Rather than simply providing pain relief and hoping for improvement, knowing which joints are affected and the severity of changes allows your vet to tailor treatment — which joints to focus on, whether specialist intervention (joint injections, nerve blocks) is appropriate, and how aggressively to treat.

X-rays for joint disease typically cost £150–£300 at UK practices. For complex or atypical cases, referral to a veterinary orthopaedic specialist for MRI or CT scanning may be recommended — these are typically available at referral centres and veterinary schools at costs of £500–£1,500 for imaging alone.

Medical Treatment Options

The cornerstone of medical management for canine arthritis is non-steroidal anti-inflammatory drugs (NSAIDs). These drugs — including meloxicam, carprofen, grapiprant, and robenacoxib — reduce pain and inflammation effectively and significantly improve quality of life. Long-term NSAID use requires 6-12 monthly blood tests to monitor kidney and liver function, but is generally well tolerated in most dogs.

Newer treatment options include bedinvetmab (Librela) — a monthly injection targeting nerve growth factor that blocks pain signals from arthritic joints. This has been transformative for some dogs who did not respond well to NSAIDs, and is available at UK vet practices. Gabapentin is sometimes added for neuropathic pain components.

Joint supplements including omega-3 fatty acids (particularly EPA and DHA from fish oil), glucosamine, and chondroitin may provide modest additional benefit alongside medication. The evidence base is stronger for omega-3 fatty acids than for glucosamine/chondroitin. Always discuss supplements with your vet, and purchase from reputable sources — quality varies widely.

Non-Medical Management

Medical treatment works best as part of a multimodal management approach. Weight management is particularly important — every kilogram of excess weight dramatically increases the load on arthritic joints. The PDSA notes that even a modest 5–10% body weight reduction in overweight arthritic dogs can produce significant improvements in mobility and pain levels.

Physiotherapy and hydrotherapy are increasingly recommended as part of arthritis management in UK dogs. Hydrotherapy (swimming or underwater treadmill) allows exercise that maintains muscle mass and joint mobility without the impact stress of walking on hard ground. Sessions typically cost £30–£60 at a registered hydrotherapy centre. Physiotherapy exercises performed at home, guided by a qualified veterinary physiotherapist, can also make a meaningful difference.

Environmental modifications at home are simple but effective: providing an orthopaedic memory foam bed (raised off cold floors); installing ramps or steps for dogs that use furniture or car boots; non-slip surfaces on smooth floors; and adjusting exercise to shorter, more frequent walks rather than single long walks, particularly during cold or damp weather when stiffness tends to be worse.

Managing Arthritis Costs Long-Term

Arthritis treatment is one of the most significant ongoing veterinary costs for UK dog owners. Monthly NSAID medication costs £25–£45 when purchased from the practice, but 40–60% less with a written prescription at an online pharmacy — a saving of £100–£250+ per year. Under the March 2026 CMA reforms, your vet must offer you a written prescription and fees are capped at £21.

Regular monitoring blood tests (£80–£150 per panel) and consultations (£40–£65) add to the annual cost. Hydrotherapy and physiotherapy, while beneficial, add further expense. Balancing these costs while ensuring your dog receives adequate pain relief is a real challenge for many owners.
