Fletcher has an appointment to get neutered on Aug. 13th (one day after turning 6 months) I wanted to get him micro-chipped but I have not done my research on them. I live in the US so if you have your dog micro-chipped please share your input on them. I'm starting my research by asking you. My vet office does not offer any and I was not able to chat with my vet about them but I do know they will happily do them. Tell me what brand you went with and why.
