Canine cognitive dysfunction syndrome (CDS) is the equivalent of Alzheimer's disease in dogs, affecting up to 50% of dogs over 15 years. Early recognition and treatment significantly improve quality of life.
Dogs with CDS experience confusion, anxiety, and disorientation that are distressing for animals whose normal cognitive function previously oriented them confidently in their environment. Waking at night confused and vocalizing, getting stuck in corners, failing to recognize familiar people, and losing house training are not merely inconveniences — they represent genuine psychological suffering from the dog's perspective. The welfare of a confused, disoriented dog who cannot understand their environment is significantly impaired. Early recognition and intervention, combined with environmental modifications that reduce confusion and anxiety, can meaningfully extend a dog's period of good cognitive function and emotional wellbeing.
