Canine cognitive dysfunction syndrome is the dog equivalent of dementia and affects a majority of dogs over 15 years old, causing disorientation, disrupted sleep, and reduced quality of life that is both treatable and underdiagnosed.
Canine cognitive dysfunction causes genuine distress that is often misattributed to normal ageing. Dogs that wander at night, become trapped in corners, or fail to recognise familiar people are experiencing neurological decline that causes confusion, anxiety, and potentially fear. Sleep disruption causes chronic fatigue and dysregulation of circadian rhythms. House soiling accidents cause distress in dogs that have been housetrained throughout their lives. Reduced engagement with family members reflects withdrawal from previously rewarding social interactions. Owners who interpret these signs as simple ageing rather than treatable disease miss the window for intervention. Management with licensed medication, environmental modification to reduce disorientation risk, and enrichment activities that stimulate cognitive function can meaningfully extend quality life. Understanding CDS as a welfare issue rather than an inevitable consequence of longevity reframes it as a condition deserving active management.
