I know I've always microchipped mine, I think most owners do. On one occasion my front door was left unlatched and my border collie escaped - the dog warden had picked him up within the hour and actually brought him back to our address for us. If your dog did get lost - and accidents do occasionally happen - even a nametag on a collar can get lost, but a microchip is permanent. If a dog is stolen, it may actually be the only way to conclusively prove the dog is yours should the police find it!
