Coco is the first dog in the world to detect a potentially fatal attack of Addison’s disease in her owner Karen.
Coco saves Karen’s life everyday by alerting her to when the cortisol levels in her body fluctuate. He stops Karen from falling into a coma at least twice a week, by detecting when her body’s cortisol falls below a certain level and fetches her medicine bag.
The Kennel Club Charitable Trust has given £25,000 to Cancer & Bio-detection Dogs , which trains dogs to detect cancer and hypo alerts in diabetics, and Coco is its first Addison’s assistant dog.
