When your out walking and a strange dog tries to attack yours to which the owner says "hes never done that before". Last year a guy was walking his two dogs across the fileds towards me so I called mine and put them on leads, this idiot is calling his dogs which ignored him and covered the three hundred yards between us, his little dogs were trying to bite my three, one a German shepherd who wanted to eat them. In the end I shouted to this guy about getting his dogs, at this point I was still thinking "these things happen". However the guy just stood there and waited for his dogs to return,
