A microchip is the most effective and safe form of identification for pets. Each microchip is a little smaller than a grain of rice. The microchipping procedure is very common and quick to perform and almost any animal can be microchipped - from ferrets to birds to horses and everything in between.
Each microchip is encoded with a 15 digit number which corresponds to your contact details on a national database. Rangers, vets and similar organisations are able to scan your pet, retrieve the number and look up your details to enable them to contact you should your pet wander and be found. A microchip is not a GPS tracker. Microchipping involves a quick, relatively painless injection into the scruff of the neck (in most animals). Blair Street Veterinary Hospital have been microchipping pets since the late 90's, and we only use the very latest "mini-chips." These are smaller than a standard microchip, meaning an even smaller needle is required.
