Osteoarthritis in Dogs: Prevention, Assessment, and Treatment

Osteoarthritis is the most common chronic pain condition in dogs, affecting over 20% of the adult population. Evidence-based management dramatically improves quality of life for affected animals.

Key Facts

Osteoarthritis (OA) affects an estimated 20-25% of adult dogs and prevalence increases with age
It is a progressive, degenerative joint disease causing irreversible cartilage breakdown and bone changes
Large and giant breeds have elevated OA risk; hip dysplasia and elbow dysplasia are leading causes
Diagnosis requires clinical examination, pain scoring, and radiography — owners often detect subtle signs first
A new monoclonal antibody therapy (frunevetmab/Librela) provides monthly injectable pain control
Weight management is one of the most powerful OA interventions — each kilogram lost measurably reduces pain

Welfare Considerations

Osteoarthritis causes chronic, progressive pain that dramatically reduces quality of life in affected dogs. The welfare gap is enormous: most dogs with significant OA are undertreated because owners attribute mobility changes to normal aging rather than treatable pain. Validated pain scales (CBPI, Helsinki Chronic Pain Index) help quantify pain severity objectively. Multimodal treatment combining pharmaceutical pain management, weight control, physiotherapy, and environmental modification outperforms any single intervention. NSAIDs remain the backbone of treatment; gabapentin provides adjunctive neuropathic pain control; frunevetmab (anti-NGF antibody) offers an effective alternative for dogs with NSAID contraindications. Physical rehabilitation — underwater treadmill therapy, therapeutic exercise — maintains muscle mass and joint mobility. Environmental modifications (orthopedic bedding, ramps, non-slip flooring) reduce daily pain burden without medication.

What You Can Do

Score your dog for pain using validated tools at home — the CBPI is freely available online for owners
Maintain your dog at optimal body weight — obesity dramatically worsens OA pain and progression
Install ramps, non-slip mats, and orthopedic bedding for arthritic dogs — these changes make daily life more comfortable
Discuss multimodal pain management with your vet — frunevetmab (Librela) is now available for dogs with NSAID concerns
Consider a formal physiotherapy assessment from a certified canine rehabilitation practitioner
