MARYVILLE, Tenn. -- The sisters were only 2 and 7 when they were diagnosed with Type 1 Diabetics and now they are trying to raise enough money to buy a life-saving diabetic alert dog.

Each girl need their own dog and they cost around $27,000 due to the extensive training and specialty service the dogs provide.

The dogs are trained through a company called The National Institute for Diabetic Alert Dogs, NIDAD for short. Trainers work with the dogs by training their 225 million scent receptors to recognize a distinctive scent that's given off during times of a low or high blood sugar event. The scent is undetectable by humans since we only have 5 million scent receptors.

In order to get these live saving dogs; a fundraiser have been set up to raise enough money.

You can follow them on Facebook at "Diabetic Dogs for Kendyl and Sydney".
