Osteoarthritis in Dogs
A progressive degenerative joint disease and one of the most common sources of chronic pain in dogs, especially as they age.
Overview
Osteoarthritis involves progressive cartilage breakdown and secondary joint inflammation. It can be primary (age-related wear) or secondary to a developmental condition such as hip or elbow dysplasia, or previous joint trauma.
Clinical signs
- Stiffness, especially after rest ("morning stiffness")
- Reluctance to jump, climb stairs, or exercise as much as before
- Lameness that may wax and wane
- Muscle atrophy over affected joints
- Behavioral changes such as irritability or reduced interest in play
Diagnosis
- Orthopedic exam findings: joint effusion, crepitus, reduced range of motion, and pain on manipulation
- Radiographs showing joint changes such as osteophytes and joint space narrowing
- Advanced imaging (CT/MRI) in more complex cases
Treatment
- Weight management - excess weight directly increases joint loading and worsens progression
- Controlled exercise and physical rehabilitation
- NSAIDs or other veterinarian-prescribed analgesics
- Joint supplements such as glucosamine/chondroitin and omega-3 fatty acids
- Newer options such as anti-NGF monoclonal antibody therapy, and surgery in select cases depending on the underlying cause
Prognosis
Chronic and progressive, but very manageable long-term with a multimodal pain-management plan. Most dogs maintain a good quality of life with appropriate ongoing care.

Frequently asked questions
Is osteoarthritis only a problem in older dogs?
It is most common in older dogs, but it can develop earlier in dogs with a developmental joint condition like hip or elbow dysplasia, or after a joint injury.
Do joint supplements actually help?
Supplements like glucosamine and chondroitin are commonly used alongside other treatments and may provide modest benefit for some dogs, but they generally work best as one part of a broader pain-management plan rather than a standalone treatment.
