i dont think it will suit some people, as you know, some dogs do get a few nicks now and then and say thoes dogs were stolen, or got out, and were later found, taken to vet to be checked, next minit the vet could be on the phone to rspca, before you know it the rspca is banging on your door, and at the end of it you still might not get your dog back, i think it might be more trouble than its worth to some people to have them chipped
