Musculoskeletal disease — including osteoarthritis, hip dysplasia, and intervertebral disc disease — affects millions of dogs and represents a major source of chronic pain that is frequently undertreated.
Chronic musculoskeletal pain in dogs represents a pervasive and frequently invisible welfare problem. Because dogs rarely vocalize pain from arthritis, owners often attribute reduced activity and reluctance to exercise to normal aging. Pain assessment tools developed specifically for dogs reveal that many owners are unaware of the pain level their dog is experiencing. Breed selection has embedded structural vulnerabilities — Dachshunds with IVDD, Bulldogs with joint problems, German Shepherds with hip dysplasia — that were human-created and are human-solvable through breeding reform. Maintaining healthy weight is the single most impactful intervention for musculoskeletal health, but approximately 50% of pet dogs are overweight. Early physiotherapy and environmental modifications — ramps, non-slip flooring — can substantially improve quality of life for affected dogs.
