My home bred English bull was on the way back from the vets with his two gsd dogs friends thay are all castrated and under 2 years old, never sparked of before, and then he grabbed one of the gsd just out of the blue, locked on dogs screaming emergency stop, me leaping into the back of the estate, the bull came out with my poor terrified gsd in his mouth, New home for that one ! with no other dogs. His mum is grumpy if she is in the house with the other dogs, so i am afraid kennel and paddock of her own. She is my 4th english, and will be the last,dont mind the odd tiff with the pack, but bull
