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 small animals is approximately 1.25 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 large animals.
