Diabetic Alert Dog tag for small animals Engraved Diabetic Alert Dog tag is made from our Tuff-Tec Plastic which makes it resistant to scratches from your animal's daily activity. Red tag for medium to large animals is 2 inches wide and reads "THERAPY ANIMAL" in bold white letters along with a design graphic. It is a great addition to hang on our Vests and Harnesses, on a collar, or even on a carrier. Designed and printed in the USA. We also have a Diabetic Alert Dog for small animals.
