Cognitive dysfunction in ageing dogs causes confusion and distress. Early recognition enables management that maintains quality of life for affected dogs.
Canine cognitive dysfunction causes genuine distress through confusion about familiar environments, disrupted sleep causing night-time restlessness, and loss of trained behaviours that may cause frustration and anxiety. A dog that stares at walls, gets trapped in corners, cannot find its way back from the garden, or vocalises anxiously at night is experiencing disorientation that is frightening rather than merely inconvenient. The welfare impact accumulates as the condition progresses. Early recognition through regular monitoring using the DISHAA criteria enables earlier intervention with dietary modification, medication, and environmental management that can slow progression and improve quality of life. Owners of senior dogs who regularly assess their dog's cognitive status are better positioned to provide timely support than those who attribute changes to normal ageing.
