Degenerative Joint Disease in Dogs — Chronic Pain Management

Degenerative joint disease (DJD) is the most common source of chronic pain in dogs, affecting an estimated 20% of the adult population, with welfare substantially improved by early recognition and multimodal pain management.

Key Facts

DJD affects at least 20% of dogs over 1 year old; prevalence rises to over 80% in dogs over 8 years
It is most common in elbows, hips, stifles, and shoulders — large breeds are disproportionately affected
Behavioural signs include reduced activity, reluctance to jump or climb stairs, and altered gait
NSAIDs (meloxicam, carprofen, grapiprant) are the first-line pharmacological treatment
Adjunctive therapies include gabapentin, amantadine, physiotherapy, hydrotherapy, and acupuncture
Canine rehabilitation physiotherapy improves range of motion and muscle mass in clinical studies
Body weight management is the single most evidence-based intervention — reducing 10% body weight significantly reduces lameness scores

Welfare Considerations

Degenerative joint disease is often called the hidden pain of companion animals because dogs are stoic by nature and owners frequently attribute signs to normal aging rather than treatable pain. The result is that many dogs live with chronic unmanaged pain for months or years before veterinary assessment. This represents a substantial welfare deficit that simple interventions can address. NSAIDs provide effective analgesia for most dogs with mild to moderate DJD and have excellent safety records when used with appropriate monitoring. Multimodal analgesia combining NSAIDs with gabapentin, environmental modification (ramps, orthopaedic beds, heated sleeping areas), and physiotherapy achieves better outcomes than single-agent therapy. Weight management deserves particular emphasis: adipose tissue is not metabolically inert but produces pro-inflammatory cytokines that worsen joint inflammation — dogs who lose excess weight show measurable improvement in mobility and lameness scores. Regular veterinary pain assessments using validated scales (CBPI, Liverpool) help track treatment effectiveness.

What You Can Do

Learn to recognise DJD signs in your dog: activity reduction, stiffness after rest, reluctance to jump
Have your dog assessed for DJD by a vet if you notice any mobility changes
Maintain healthy body weight in your dog — obesity dramatically worsens joint pain
Provide orthopaedic bedding, ramps, and non-slip surfaces to reduce joint stress
Discuss multimodal pain management with your vet rather than relying on NSAIDs alone
Consider canine physiotherapy referral for dogs with moderate to severe DJD
