I nearly lost Bradley the other day, I had just got him out of the car and noticed that his lead and been unclipped from his collar. No one had got to him as I was with him the whole time. He just ran off and wouldn't come back. Luckily a friend managed to catch him for me. It is not the first time that I have known this to happen as I know others that it has happened to. No idea what happened or how it was unclipped as I know it was on right. The only thing that I can think of is that his ID disc caught the "lever" on the clip and opened it.
