Seriously, she has been aggressive for a while now, I have tried so many different things, Ive had muzzles on her, she is awful with other dogs - she just hasnt been this bad with her own dogs until now, the vet said they couldn't be left together again. I wouldn't pass on the problem to someone else. I really am gutted, I loved her to bits and she was so good at rabbiting. Its a sad day - one which will stay with me for a long time.
