Canine cognitive dysfunction syndrome parallels human Alzheimer's disease and is underdiagnosed, with significant welfare implications for affected dogs.
Dogs with cognitive dysfunction experience confusion, anxiety, and disrupted sleep that profoundly reduce quality of life. Nighttime waking and vocalization is distressing for both dog and owner. The normalized acceptance of cognitive decline as 'just old age' allows preventable suffering to persist without treatment. Early diagnosis allows intervention at a stage where medications and environmental modifications provide meaningful benefit. Quality of life assessment tools help owners and vets make end-of-life decisions compassionately.
