Our American Bulldog, Knuckle Head, got out of the yard when we were gone and was picked up by the pound. The pound scanned Knuckle Head which notified PetLink, and then I received a call direct from PetLink to let me know where our dog was and how long he had been there. This was wonderful news! It was a Friday evening and the pound was closed so we had to wait until Monday to bail Knuckle Head out, but it sure was a blessing to know where he was and when we could go get him. If we had not used a chip that identified him and because he is an American Bulldog they might have put him to sleep! Thank you all for the PetLink chip which helped with a very fast return of pet.
