The other side of the best friend charm, what cute dog tags! You know you love each other, and can't be separated. Either you can get the other one for you to add to a backpack, a key ring for identification not only for who owns the keys but for who is best friends with who.  Of course, it could be your pets love each other, and you seldom see one of those furry pals without each other.   These pet tags will share their secret.  Personalize the back of your custom dog tag for pets with four lines of text to have your pet returned if they are ever lost.
