Canine cognitive dysfunction syndrome is a progressive neurological condition equivalent to Alzheimer's disease, affecting millions of senior dogs.
Dogs with cognitive dysfunction experience a progressive deterioration in quality of life as their ability to understand their environment, navigate their home, and interact normally with their family diminishes. Night waking and disorientation cause distress in affected dogs and significant welfare impact. Owners who do not recognise the condition as a medical problem rather than a behavioural one may inadvertently worsen it through inappropriate responses to altered behaviour. Early diagnosis through veterinary assessment allows treatment to begin before the condition is advanced. Quality of life monitoring is essential as the condition progresses to inform end-of-life decisions.
