Ok i just called Avid. It's 18.50 for them to put my information in so if Cody is ever lost they will have my number directly.
When i had him checked by the vet i got a puppy packet with free stuff and one of it was heartguard and in there came with this getmehome tag so i registered him there so if he ever gets lost they have my info.
but like you know anyone will bring him back. lol
i just hope he never gets lost from me
