My old dog bounced off allsorts over his career but the worst he ever did was break a nail running on a track and chip a couple of his canine teeth striking bricks on the way out to squatters. He hit my car flat out, ditch banks, trees etc etc and shook his head and run off but that first plough at 6yr old finished him off. It seems to have been night after night of lamping weather since he died too to rub salt in my wounds.
