Little Sadie is a 4-year-old girl dealing with type 1 diabetes. Sadie's parents do everything they can to care for her and her condition, including getting a diabetic alert dog.
Hero is an assistance dog who has been trained to alert Sadie and her parents when her blood sugar is dangerously low. Hero can actually SMELL Sadie's blood sugar.
Sadie and Hero quickly bonded so when Hero started acting strangely while Sadie was at school 5 miles away, Sadie's mom took it seriously. She called up the school and told them to check Sadie's blood. Sure enough, her blood sugar was at dangerous levels. Watch the incredible story below.
No one is quite sure how Hero managed to detect that Sadie was in trouble from such an incredible distance, but thankfully he did!
