I have two, 21 week old Buff Roosters that go after my dog. They are about the size, or even bigger, then my little toy poodle dog, Pepper. Before, when they were smaller then him, they didn't try to hurt Pepper at all. Now, my dog is scared to go in the backyard because of the roosters. They don't have spurs yet, but they are getting bumps. I want to resolve this issue before they get their spurs. Is there anything I can do? I really don't want to get rid of them...
