Tuffee is our Border Collie. She was 6 years old as of Feb. 15. As you may know BC's are herding dogs. So Tuffee is determained to herd our horses since we don't have any sheep. In this photo she is trying to herd Sundance, my paint gelding. But horses don't herd as well as sheep do. So instead of moving like Tuffee wants him to do. He will just stand there and once in a while raise a back hoof to threaten her or to tell her to leave him alone. When she botheres him to much he will make a half hearted kick at her. He has been known to actually kick her enough to make her yelp but never enough to actually hurt her. So Far. And I hope he never does. Two of our other horses, Nita and Star treat her the same way. But Trave, one of the ponies will only take her "herding" so long and then he will charge at her and try to stomp her with his front hooves. The dumb dog doesn't seem to learn not to bother the horses. Maybe it is her way of finding adventure in an otherwise dull life. When I see she has bugged him enough I tell her to get OUT. She knows that means to leave him alone and get out of his pen. I am glad she only trys to herd the horses when I am out in the pen with them. She never goes in their pens when I am not in there.
