Yes, specially trained dogs—often called Diabetic Alert Dogs (DADs)—can smell high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia) by detecting chemical changes in a person's breath and sweat. They use their acute sense of smell to alert owners to dangerous levels before they become symptomatic, sometimes detecting glucose changes that a human wouldn't notice.

How do dogs know when blood sugar is high?
