Osteoarthritis in dogs: managing chronic joint pain
Osteoarthritis is far more common than most owners realise — by middle age, around a fifth of all dogs have some degree of OA, and in older dogs the figure climbs sharply. It's progressive, painful, and the leading cause of chronic pain in dogs worldwide. Most cases are secondary to a developmental problem (hip or elbow dysplasia, OCD, cruciate disease) or to old joint injuries.
Modern multimodal management is hugely better than what was available a decade ago. The pillars are: weight control (the single most effective lever — slim dogs feel dramatically better), regular low-impact exercise, joint-targeted nutraceuticals (omega-3s, green-lipped mussel), NSAIDs (carprofen, meloxicam, grapiprant), the newer monthly anti-NGF injection bedinvetmab (Librela), and physiotherapy or hydrotherapy. The goal isn't to cure the joint — it's to keep the dog comfortable and moving for as many good years as possible.
What vets typically check for
- Orthopaedic exam — identify which joints are affected, severity of pain on flexion/extension.
- Radiographs of the most painful joints, often under sedation for proper positioning.
- Body condition scoring + targeted weight-loss plan if overweight (often the single biggest intervention).
- Multimodal pain plan: NSAID + omega-3 + joint diet ± bedinvetmab (Librela) ± physical rehab.
- Surgical referral for joint-specific options where appropriate (e.g. TPLO for CCL disease, hip replacement for severe hip OA).

Frontiers in veterinary science · 2025 · United Kingdom
In a study comparing two treatments for pain from osteoarthritis in dogs, researchers looked at bedinvetmab (a new medication) and meloxicam (a common anti-inflammatory drug). They included 101 dogs with osteoarthritis and found that both treatments helped reduce pain, but bedinvetmab seemed to have a slightly better effect, although it wasn't statistically significant. The dog

Scientific reports · 2026 · United States
In a study involving 32 dogs over one year old and weighing more than 20 kg, researchers compared two medications, bedinvetmab and grapiprant, to see which one was more effective at relieving pain from osteoarthritis (a joint condition) in the hips and/or knees. The dogs were randomly assigned to receive either bedinvetmab once a month with a placebo daily or grapiprant daily w

Open veterinary journal · 2025 · United States
Canine osteoarthritis (OA) is a common and painful joint condition in dogs that gets worse over time and affects their quality of life. Since there is no cure for OA, the focus has shifted to a combination of treatments that can help manage the symptoms and improve the dog's well-being. These treatments may include managing the dog's weight, physical therapy, medications like a
Frequently asked questions
- Is my dog 'just slowing down' or is it pain?
- Most owners under-recognise the pain of OA because dogs hide it well. The classic signs are slow to rise, stiff after rest that warms out of, reluctance to climb stairs or jump, lagging on walks, or new irritability. If any of these apply, ask your vet about a pain trial — a 2-week NSAID trial often reveals just how much pain the dog was in.
- Are joint supplements actually worth it?
- The strongest evidence is for omega-3 fatty acids (fish oil) and prescription joint diets. Glucosamine/chondroitin has weaker evidence but is widely tolerated. Green-lipped mussel extract has modest evidence too. None replace pain medication when the dog is actively painful.
- What about Librela (bedinvetmab)?
- Librela is a once-monthly injectable monoclonal antibody that blocks nerve growth factor (NGF), a key pain signal in OA. Many dogs respond dramatically. It's an option for dogs who can't tolerate NSAIDs (kidney or liver disease) or who need additional pain control on top of NSAIDs.
