Canine cognitive dysfunction syndrome is an underdiagnosed condition in older dogs, causing significant welfare impacts. Early recognition and evidence-based management can substantially improve quality of life for affected animals.
CDS represents a growing welfare challenge as dogs live longer due to advances in veterinary care and nutrition. Dogs with advanced cognitive decline experience confusion, anxiety, and disrupted sleep that cause genuine suffering, often without owners fully recognizing the connection between behavioral changes and the dog's welfare state. Early diagnosis and intervention - through medication, dietary modification, and environmental management - can meaningfully extend quality of life. The welfare obligation of ownership extends to recognizing when cognitive decline has progressed to the point where quality of life can no longer be adequately maintained, and making end-of-life decisions based on the dog's welfare rather than owner attachment.
