Canine cognitive dysfunction is the dog equivalent of Alzheimer's disease, causing confusion, disorientation, and sleep disturbance in older dogs.
Dogs with cognitive dysfunction experience confusion, anxiety, and loss of familiar routines that were central to their wellbeing. Night-time restlessness causes suffering for both dog and owner. Early diagnosis allows intervention that slows progression. End-of-life decisions should consider quality of life carefully in dogs with severe cognitive decline.
