Dog Cognitive Dysfunction Syndrome Early Detection

Canine cognitive dysfunction syndrome (CDS) is underdiagnosed in senior dogs, with early detection enabling intervention that preserves quality of life.

Key Facts

CDS affects approximately 28% of dogs aged 11-12 and 68% of dogs aged 15-16
The DISHA framework describes CDS signs: Disorientation, altered Interactions, Sleep-wake cycle changes, House-soiling, Activity changes
CDS is distinct from hearing and vision loss, which can mimic some signs
Selegiline (Anipryl) is the only FDA-approved medication for CDS in dogs and improves signs in about 70% of cases
Dietary supplementation with omega-3 fatty acids, antioxidants, and medium-chain triglycerides may slow progression

Welfare Considerations

CDS causes confusion, disorientation, and apparent anxiety that represents genuine suffering. Dogs experiencing night-time waking and vocalization, house-soiling accidents, or apparent failure to recognize familiar people are showing signs of distress. Early detection and treatment improves welfare by reducing confusion and maintaining cognitive function. Environmental modifications - consistent routines, nightlights, and reduced furniture rearrangement - reduce disorientation. Quality of life assessment tools help owners and vets make informed decisions about advanced disease management.
