I was given a phone number that the chip was origionally registered with, but the woman does not answer her calls or return messages left. Maybe the dog was sold or given away after the chip was put in. I have no idea, but this is an extremely large dog and needs to go back to it's owner's. The vet clinic is not returning messages yet, after the holiday, but it is an Austin phone number. The phone number for the person who bought the chip is a 409 area code. This dog is a Great Pyraneese.
