Four-year-old Sadie has type 1 diabetes and Down syndrome, which means that it’s very important to keep her blood sugars stable, but can be difficult to monitor. So, Sadie’s family had a special Labrador, named Hero, join their family to help with exactly that. Hero is a trained diabetic alert dog, and with his special nose, he can tell when Sadie’s blood sugar is too high or too low, and will alert her parents by doing anything he can to get their attention, like whining, pawing, or nosing them.
