Dog Cognitive Dysfunction Syndrome: Recognition and Treatment

CDS is the canine equivalent of Alzheimer's disease, affecting a growing proportion of elderly dogs; early recognition and multimodal management improve quality of life significantly.

Key Facts

CDS affects up to 68% of dogs aged 15-16 years and is likely underdiagnosed
The DISHAA acronym captures signs: Disorientation, Interactions changed, Sleep disrupted, House soiling, Activity changed, Anxiety increased
Selegiline (Anipryl) is FDA-approved for CDS and may slow progression
Environmental enrichment and daily routine maintenance help affected dogs navigate daily life
New therapeutics including Vetmedin for CDS are under investigation

Welfare Considerations

Dogs with unrecognized CDS suffer the confusion and anxiety of cognitive decline without appropriate support. Owners who interpret CDS signs as behavioral problems and respond punitively cause additional distress. Recognition enables environmental modifications - night lights, consistent routine, toileting access - that meaningfully improve daily experience. Pharmacological support combined with enrichment and routine provides the best welfare outcome.

What You Can Do

Ask your vet specifically about CDS assessment for any dog over 11 showing behavioral changes
Implement consistent daily routine and avoid furniture rearrangements that disorient cognitively impaired dogs
Provide nightlights to reduce disorientation in dogs wandering at night
Discuss selegiline therapy with your vet as an FDA-approved option for confirmed CDS
