Radar was tattooed when I got him, I didn't have it done. His breeders in Canada had it done. I'm gonna have all my dogs microchipped tho. None are yet but they all will be before the summer is up. My dogs just don't leave the house or yard LOL...my gates are always locked with a pad lock and they don't run out the door. They are never let out in the back yard unless we are home...but......to be on the safe side they will all be microchipped very soon
