As you might recall, we are obtaining a young LGD. Mostly Great Pyrenees. Well, two of my adult does are highly dog aggressive. Hope and Rudy. They don't hesitate to go AFTER a dog and head butt it as hard as they can. They don't run, and will even smash the fence if a dog is on the other side. None of my younger does or Hallie has a problem with dogs, but Hope and Rudy are extremely aggressive. Even if I am standing with the dog (for example, my poor loving Boxer) they will do their best to tup her into the next state. I already plan to give the puppy a "safe place" to get away from Evil 1 and Evil 2, but what else can I do? Recommendations?
