Chronic pain in dogs — from osteoarthritis, neuropathy, and other conditions — is the most prevalent and undertreated welfare problem in companion animal medicine.
Canine chronic pain represents the largest welfare gap in companion animal medicine — millions of dogs live with treatable pain that owners normalize as aging. The masking behavior that served ancestral dogs by hiding weakness from predators now prevents accurate pain communication in domestic dogs, causing owners to miss significant suffering. Veterinarians can miss subtle signs during brief examination unless specifically screening for pain. Treatment has improved dramatically: NSAIDs, gabapentinoids, physical rehabilitation, adequately dosed pain management, and newer targeted therapies provide substantial relief when properly implemented. The welfare investment of treating chronic pain in older dogs is high: improved mobility, restored normal behavior patterns, and apparent improvement in positive emotional state represent genuine quality of life gains that profoundly matter for dog welfare in their final years.
