Osteoarthritis in Dogs: Managing Chronic Joint Pain

Osteoarthritis affects an estimated 80% of dogs over 8 years old and is one of the most common sources of chronic pain in companion animals.

Key Facts

Osteoarthritis (OA) is a progressive, degenerative joint disease causing pain, stiffness, and reduced mobility
It affects approximately 20% of all dogs over 1 year and up to 80% of dogs over 8 years
Dogs rarely vocalize joint pain; owners often misattribute reduced activity and reluctance to play to normal aging
Weight is the single most modifiable risk factor — overweight dogs have significantly accelerated OA progression
Multimodal pain management combining NSAIDs, joint supplements, physiotherapy, and environmental modification is most effective
A new class of anti-nerve growth factor antibody medications provides significant pain relief in OA dogs

Welfare Considerations

Chronic pain from osteoarthritis is pervasive and undertreated in dogs. The instinct to mask pain, combined with owner difficulty distinguishing gradual behavioral change from normal aging, means many arthritic dogs live with significant discomfort for years before diagnosis. Pain assessment tools including owner questionnaires and force plate analysis have improved diagnosis. Treatment has advanced substantially — anti-NGF antibody therapies, laser therapy, and physiotherapy complement traditional NSAIDs to provide better pain control with fewer side effects. Every arthritic dog deserves an active pain management plan rather than the passive acceptance of "getting old."

What You Can Do

Discuss pain assessment for your senior dog at annual veterinary visits even without obvious symptoms
Maintain your dog at a healthy weight — reducing body condition by even one score reduces joint pain significantly
Provide orthopedic bedding and ramps or steps to reduce impact on arthritic joints
Ask your veterinarian about the full range of pain management options including newer antibody therapies
