Dog Cognitive Dysfunction Syndrome: Recognition and Management

Canine cognitive dysfunction is an Alzheimer's-like condition affecting senior dogs that is underdiagnosed and undertreated.

Key Facts

CDS affects an estimated 28% of dogs aged 11-12 and 68% of dogs over 15
Signs include disorientation, altered sleep, reduced interaction, and house soiling
Selegiline and propentofylline are licensed veterinary treatments for CDS
Environmental management and cognitive enrichment slow decline in some studies

Welfare Considerations

CDS causes significant confusion and distress in affected dogs. Owners often attribute signs to 'normal aging' and do not seek treatment. Early diagnosis and multimodal treatment significantly improve quality of life in the final years.

What You Can Do

Use the DISHAA questionnaire to screen senior dogs for CDS signs
Consult a vet about selegiline or other treatments for diagnosed CDS
Provide cognitive enrichment - puzzle feeders and gentle training - to slow decline
