The Paw Print Charm is one of our “Fun” items. Most people purchase the charm in the pet’s month of birth or if it is a rescue, they get the month they were adopted. They can be put on key chains, as a purse fob, or a zipper pull. However, these are not recommended to be placed on the pet’s collar. Some ladies have liked them so much that they just got their own birthstone since the did not have a pet.
