Canine cognitive dysfunction syndrome is a progressive neurodegenerative condition in older dogs analogous to Alzheimer's disease, requiring compassionate management of late-life welfare.
CCD causes significant welfare deterioration as it progresses. Spatial disorientation — becoming lost in familiar rooms, getting stuck in corners — causes confusion and distress. Disrupted sleep-wake cycles result in night-time restlessness that distresses both dog and owner. Anxiety increases as familiar routines and environments become confusing. Loss of housetraining is distressing for dogs accustomed to cleanliness. Pain assessment is important — concurrent pain conditions often worsen CCD signs. The welfare challenge is that CCD is progressive and incurable, requiring ongoing adaptation of care as the dog's needs change. Quality-of-life assessment must be regular and honest, with euthanasia considered when distress outweighs moments of positive experience.
