Canine cognitive dysfunction syndrome (CDS) is the dog equivalent of Alzheimer's disease. Understanding and managing this condition is essential for senior dog welfare as the population of aging companion animals grows.
CDS welfare encompasses both the suffering of dogs experiencing disorientation and anxiety and the difficulty for owners in recognizing and managing the condition. Dogs with advanced CDS may appear confused, anxious, and distressed without owners understanding the cause. Night-time restlessness and vocalization affect both dog and human welfare. Welfare management includes environmental modifications (night lights, consistent routine, easy access to outside), veterinary treatment, and quality-of-life assessment to inform end-of-life decisions. Early recognition and intervention are associated with better welfare outcomes.
