Canine cognitive dysfunction syndrome is the dog equivalent of dementia, affecting millions of older dogs with confusion, anxiety, and disrupted daily life, yet it remains under-diagnosed and under-treated despite effective interventions.
Dogs with CDS experience a form of suffering that is invisible to many owners — they see a dog that appears physically healthy but fail to recognise the confusion, anxiety, and loss of learned associations that define cognitive decline. Night-time restlessness, house soiling after years of reliability, and apparent failure to recognise familiar people or places are distressing for the dog even when the owner interprets them as nuisances. Welfare-focused management includes both treating the neurological condition and adapting the environment to reduce confusion and anxiety for the affected animal.
