Dog Degenerative Joint Disease: Recognising and Managing Chronic Pain

Degenerative joint disease (DJD) or osteoarthritis affects a majority of older dogs and represents one of the most common sources of chronic pain in companion animals.

Key Facts

An estimated 20% of all adult dogs and over 80% of dogs over 8 years have radiographic evidence of DJD.
DJD is frequently underdiagnosed — owners interpret reduced activity as normal ageing rather than pain.
Large breeds including Labradors, German shepherds, and golden retrievers are at highest risk.
The condition involves cartilage degradation, bone remodelling, and joint inflammation causing chronic nociceptive pain.
NSAIDs remain the most evidence-based pharmacological treatment; newer options include monoclonal antibodies targeting nerve growth factor.

Welfare Considerations

The welfare impact of DJD in dogs is profound but chronically underestimated. Dogs mask pain through evolutionary adaptations as prey animals in their ancestry and as socially bonded animals that suppress vulnerability displays. Studies show significant discordance between owner-reported pain and veterinary assessments. Validated tools including the Liverpool Osteoarthritis in Dogs (LOAD) questionnaire, the Canine Brief Pain Inventory, and the Helsinki Chronic Pain Index help owners and vets systematically assess pain. Welfare management is multimodal: pharmaceutical analgesia, physiotherapy, hydrotherapy, weight management, environmental modification (ramps, non-slip surfaces), and in some cases joint surgery. Regular reassessment prevents undertreated chronic pain from becoming a long-term welfare problem.

What You Can Do

Complete the LOAD questionnaire for dogs over 7 years and share results with your vet.
Ensure dogs maintain a healthy body weight — each kg of excess weight increases joint load substantially.
Consider certified canine physiotherapy and hydrotherapy for DJD management.
Install ramps, non-slip mats, and orthopaedic bedding to reduce joint stress at home.
Advocate for routine pain assessment at all vet appointments for senior dogs.
