he had a collor and tags when he was with my friend, I have no idea now though. from what I know of what happend though is that some friends of stephs uncle were over there helping fix a fence, and they did not know that sparky was not trained to not run off(I guess his other dogs are, but if you remeber sparky was an outdoor dog with little training) and they left the door open, her uncle cought him the first time and put him in the shed so he couldent escape, but when he went to get sparks from the shed he was gone an even worse part is that sparky is an intact male.
