My dog killed the rabbit we found today. He shook it to death. When Nana Sophie looked out the window she saw the dog standing over the Rabbit, with it lying there lifelessly. Nana Sophie tried defending the dog, but he could go for my cat next cos' hes killed something and he always chases my cat and bites it. We live on a farm too, so he could kill chickens, or other farmers stock. Advice needed, what to do with Rosco?
