Incredible! This dog smells his owner's saliva so he can protect her at night

We've all heard the saying that dogs are man's best friend, and the bond between this young girl and her puppy proves this. 

Nine-year-old Sophie was diagnosed with Type 1 diabetes when she was just five-years-old. Ever since, her family has been constantly monitoring her glucose levels for fear that their little girl could go into cardiac arrest if her sugar levels dip too low. 

However, while they have two special devices (an insulin pump and a glucose monitor) to help her during the day, the problem is at night because she can experience night-time lows. 

"She could go into cardiac arrest or die very quickly if she goes too low," her dad, Michael, told The Doctors. 

The family heard that diabetic alert dogs are able to predict a blood sugar change 15 minutes before a device can, which is how Honey came to join their family. 

At the moment, the pup is being trained to detect when Sophie's blood sugar changes. Dog trainer Carleigh uses samples of Sophie's salvia to get Honey used to the smell of certain levels, and gives her rewards every time she gets it right. 

However, as Carleigh admits herself, the tough part is training Honey to detect and be able to wake up whenever Sophie's levels change in the middle of the night. 

"Night time alerts are the hardest to teach a dog, Carleigh explained. 

"They have to wake themselves up out of their own sleep so that they can help their person."

Wow, what an incredible dog.
