Thanks!! He's actually in Murphy. I've got someone in Ft. Worth who will go get him if necessary. I finally called the number on the tag myself. He got a rabie shot in Garland at Banfield in October and he is registered to someone in Murphy but they would not give me the address said only to the police or licensed vet. Called the police who said they couldn't get through to anyone. We made it very clear that this dog would not go to the vet and that we would keep the dog until the owner could be found or just keep him.
My niece will keep him for now, she's off tomorrow and will try to find the owner. The police said they would scan him for a chip tomorrow.
Right now he's just scared and yippy. He's fine if she holds him.

he's about 3 lbs.
Thanks for your help
