What is the purpose of a diabetic service dog?

The purpose of a diabetic service dog is to monitor the blood sugar level of a person with diabetes and to help them maintain a normal blood sugar level. Dogs can be trained to recognize when the blood sugar level is higher or lower than it should be through their owner's scent.

When a diabetic service dog notices that his owner's scent has changed, he alerts the owner until the level is normal once again. He will also notify those around the owner if the owner is not responsive. In this way, diabetic dogs can save the lives of their owners. The dogs are trained so that they are able to accompany their owners to a variety of places so that they can provide support from anywhere.
