This rectangular engraved Hearing Dog tag is made from scratch resistant plastic and it is engraved so the lettering will not wear off. On the front of the tag it reads HEARING DOG. The rear side is not engraved. The tag is Black in color (tag color may vary) with bright, white engraved letters. The shape of the Service Dog Access Tag is a rectangle and the size measures 2.25 by 1.13 so it is easy to read. This service dog tag is a great addition to hang on our Service Dog Vests and Harnesses or even on a collar.
