am reading a book at the moment, from the USA. now it says that many owners tattoo their dogs, most choose the inside of the rear right thigh as an ear tattoo can easily be cut off.[ouchy!] they use there national security number or the dogs registration number... now my question is, can we do this in the UK? and do you think it would be better than micro-chipping? and if you had the choice which would you choose? not that i would although it does say "there is no pain, although a few dogs don't like the buzzing sound" all my dogs are micro-chipped, i don't think I'd like to see them be tattooed TBH.
