Three year old Olivia Hamilton from Gloucester has diabetes. Her blood sugar levels needs constantly monitoring. Too low and she needs to be given fast acting sugar. Too high and she needs insulin. Without treatment, she could fall into a diabetic coma, have a fit or long term damage could be caused to her body.

Which is why Olivia's parents decided to buy and a puppy and train it to detect changes in the little girl's blood sugar levels. At just 15 weeks old, Bonnie's already proving a life saver.
