Fox poo is the favourite here lol. Not that it smelt... but this morning on a walk, we went past an injured pigeon, which was floundering and obviously unable to fly. My cocker got hold of it, while my mum tried to stop him, and he must have broken it's neck in seconds. I was mortified. I hadn't been able to decide whether to try to rescue it, or just hope he put it out of its misery quickly... while he seemed quite proud of himself... he let me take it off him, albeit a bit reluctantly... dogs being dogs...
