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).

- Initial Experience of Appendicular Fracture Fixation with Low Profile Titanium Alloy Locking Plates: A Retrospective Study of 30 Fractures.
Veterinary and comparative orthopaedics and traumatology : V.C.O.T · 2026 · United Kingdom
A small dog or cat with a broken leg was treated using a special titanium plate system to stabilize the fracture. Out of 30 fractures treated, a few had complications, including some issues with the plates and wires used for repair. However, most pets showed good healing and were able to regain full or acceptable function after treatment. The titanium plate system appears to wo
- Placement of humeral transcondylar screws in dogs with humeral intracondylar fissures using preoperative computed tomography planning and a novel aiming guide.
The Journal of small animal practice · 2026 · United Kingdom
A group of 32 dogs, mostly English springer and cocker spaniels, underwent surgery to fix humeral intracondylar fissures, which can cause elbow pain and mobility issues. Using preoperative CT scans and a special aiming guide, veterinarians successfully placed locking screws in the dogs' elbows without any need for repositioning. While there were some minor complications in a fe
- Effects of spray-dried animal plasma on inflammatory indicators, antioxidant capacity, and joint health in senior dogs.
Journal of animal science · 2026 · China
A group of senior dogs with osteoarthritis (OA) were given a special diet that included spray-dried animal plasma (SDAP) to see if it would help their joint health. After 42 days, the dogs on the SDAP diet showed improved protein digestion and lower levels of inflammation markers in their blood. They also had less lameness, meaning they were moving around better and experiencin
- Diagnostic value of abduction angle and magnetic resonance imaging in dogs with arthroscopically confirmed medial shoulder instability.
The Canadian veterinary journal = La revue veterinaire canadienne · 2026
A 6-year-old mixed-breed dog was brought in for limping due to shoulder pain, and the veterinarian suspected medial shoulder instability (MSI). To diagnose the issue, the vet measured the shoulder abduction angles and performed an MRI. The angle test showed a significant difference between the affected and healthy shoulder, confirming MSI with 100% accuracy, while the MRI was l
- Effects of pentosan polysulfate sodium on joint structure and function out to six months in naturally-occurring canine osteoarthritis.
PloS one · 2026 · Australia
A group of mixed-breed dogs with osteoarthritis (a common joint condition) received weekly injections of a treatment called pentosan polysulfate sodium (PPS) for six weeks to see if it would help with their pain and mobility. The dogs that got the PPS showed significant improvements in pain levels and joint function, with better walking patterns and increased cartilage volume e
- Osteoarthritis has a high prevalence in dogs undergoing routine dental prophylaxis.
Journal of the American Veterinary Medical Association · 2026
A group of medium to large dogs, aged 4 to 10 years, were brought in for routine dental cleanings and were found to have a surprisingly high rate of osteoarthritis (OA). In fact, 60% of the dogs had signs of OA in one or more joints, even though many owners were unaware their pets had any issues. Commonly affected joints included the hips, knees, and elbows. This study suggests
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.
