Cognitive dysfunction syndrome (CDS) is a progressive neurodegenerative condition in senior dogs similar to Alzheimer's disease. Early recognition and management improve quality of life.
CDS causes progressive welfare harm through confusion, anxiety, disrupted sleep (causing nighttime distress), and loss of familiar routines that previously provided security. Dogs with CDS show clear signs of distress — nighttime howling, panting, and inability to settle reflect genuine disorientation and fear. Families who attribute these signs to normal aging rather than treatable CDS allow preventable suffering to continue. Environmental modifications (night lights, consistent routines, puzzle enrichment), supplements, and medication combine to meaningfully improve welfare in affected dogs.
