Oh I understand working with them to prevent that from happening. I don't that'll be a problem. The lab mix my boss owns is more prone to herding the horses then the bc mix he has.
I wouldn't count on that being the norm. Gusto is half-BC; he is *not* permitted loose around horses other than Tristan. He will get killed in a heartbeat. It isn't even herding that he does, it is just very much in his head that We Stay Behind The Livestock.
