NASHVILLE, Tenn. (WTVF) — The original Predators office dog, Duncan, is nearing retirement age, but he's not just an office dog.

Duncan has worked as a Diabetic Alert Dog for seven years. His age and some medical issues are forcing him to retire a little early.

Part-time Predators employee and Duncan's owner, Ron Zolkower, has just three months to raise the 20-thousand needed for a new dog. Ron is a type one diabetic, and Duncan is trained to alert him when his blood sugar levels rise or fall.

These Diabetic Alert Dogs go through two years of training through a program called "Eyes, Ears, Nose and Paws." They're even able to grab juice from the fridge and get help.
