Canine Cognitive Dysfunction Syndrome (CDS) is a progressive neurological condition affecting senior dogs. Early recognition and management can maintain quality of life significantly longer.
CDS causes genuine distress through confusion, disorientation, and disrupted sleep-wake cycles. Dogs that become trapped in corners, vocalize in apparent confusion at night, or fail to recognize their owners are experiencing something analogous to dementia - a profoundly disorienting state. The night-time vocalization that commonly accompanies CDS disturbs both the dog and the household, often leading to sleep deprivation for all involved. The progressive nature of CDS means welfare deteriorates over time - the management goal is to slow progression and maximize comfortable days. End-of-life decisions for CDS are complex because physical health may remain reasonable while cognitive suffering is severe.
