Canine cognitive dysfunction syndrome (CDS) is increasingly recognised as a form of dementia in dogs, causing anxiety, disorientation, and significant welfare decline in ageing pets.
Canine cognitive dysfunction causes progressive psychological suffering. Disoriented dogs experience the distress of not recognising familiar environments, people, or routines. Night-time restlessness — often involving vocalisation and wandering — indicates the disruption of sleep-wake regulation that mirrors human dementia. Anxiety from loss of familiar cognitive anchors is a primary welfare concern. House-training regression causes distress in dogs previously reliable for years. Early detection through owner-completed cognitive assessment questionnaires enables earlier intervention with treatments that slow progression. Environmental stability — consistent routines, familiar layouts, continued social engagement — helps maintain orientation and reduce anxiety in cognitively affected dogs.
