does anyone know of a vet in the north east that does dog id tattoo's?

Hi,
Contact the National Dog Tattoo Register.

I think you will find it difficult to fond a vet to tattoo your dog as there are only a handful that do tattooing

But there will be a tattooist in your area & you can contact them directly by visiting the link on the previous post

if you are going to get your dog tattooed why not have it microchipped too then it has double the chance of being found if lost/stolen/stray etc. we chip all our dogs and pups ourselves and it works out about the same price as tattooing, it is a very good scheme run by the KC called petlog.
