Hey. I have a problem with my dog Ziggy. She don't get along with any of the other dogs. She about kills Muffin. When Muffin goes outside she will attack her and make her bleed. So usually we leave Ziggy on a leash when all the pups are outside. Now she is not letting Bouncer eat. We put the food in 2 different places and she goes wild. What should I do?? I love this dog, but I don't want any other dog to get hurt.
