Senior Dog Cognitive Dysfunction Welfare

Recognizing and supporting dogs with canine cognitive dysfunction to maintain quality of life.

Key Facts

Canine cognitive dysfunction syndrome affects an estimated 14-35% of dogs over 8 years, rising with age
CDS symptoms include disorientation, sleep-wake cycle disruption, house soiling, and reduced interaction
CDS is underdiagnosed because owners often attribute symptoms to normal aging rather than treatable cognitive decline
Selegiline is licensed for CDS treatment in several countries with documented improvement in behavioral signs
Environmental management including night lights, consistent routines, and maintained exercise supports CDS dogs
Nutritional interventions including omega-3 fatty acids and antioxidant diets have demonstrated some benefit

Welfare Considerations

Canine cognitive dysfunction represents an emerging welfare challenge as the companion dog population ages. Dogs with CDS experience genuine confusion, disorientation, and disrupted sleep that constitute welfare harm. The welfare failure occurs not from lack of available interventions but from underdiagnosis — owners assuming symptoms are normal aging when they are not. Proactive cognitive screening in senior dogs, combined with early intervention when decline is detected, extends the period of comfortable cognitive function and reduces the severity and distress of late-stage decline.

What You Can Do

Use the DISHAA questionnaire to screen for cognitive dysfunction signs in your senior dog annually
Discuss selegiline and other CDS interventions with your veterinarian if your dog shows symptoms
Maintain consistent daily routines and familiar environments for dogs with cognitive decline
Provide regular gentle exercise, social interaction, and cognitive stimulation to support brain health
