A dog's detection of low blood sugar: a case report.

One of the life threatening complications of diabetes is hypoglycaemia. It is a common complication, with times of greatest risk being before meals and during the night. Symptoms usually develop when the blood glucose level falls below 3.5 mmol/l. Many patients with long-standing diabetes report loss of warning symptoms. Prevention of such hypoglycaemic attacks is highly desirable. Recently a dog's ability to detect hypoglycaemia in diabetic patients has been recorded. This is the first recorded case of hypoglycaemia in a non-diabetic patient being detected by a dog and also we believe it to be the first report of hypoglycaemia being detected by a dog in this country (Ireland).
