I didn't really get to pick and just went with my vet. They use AKC reunite. My older girl does not have a chip. Joey does and he got his when he was neutered and Penny does and got hers when she was spayed. Ollie will get one when he gets neutered at 7 months. Since the AKC is the Untied States only reputable registry I would think their chips are good ones.
