That's what we all sort of figured. That since all these horses grew up on the same farm and they are all aggressive with dogs, that it is a learned behavior. One of the owners thinks there were a lot of coyotes there. As far as I could tell, the horses were always turned out on beautiful safely-fenced open hillside pastures with no shelters. They had wonderful views. Maybe they could see the coyotes coming. Every one of them will attack a dog with front feet and teeth. Yrsa sure taught my big lab puppy to stay out of the barnyard. Nancy
