OK, cow horses.
Adults and the babies tend to want to follow and chase. Doesn't matter if it's a cow, dog, cat, or a goat. Our neightbor will turn out cows in the pasture next to our mare pasture at differant times during the winter. It's always fun to watch the babies go to the fence to play with the calves. They chase up and down the fence and those calves, I swear I think some of them enjoy it cause they just come back for more. Funny thing too is some of the cows will hang out at the fence next to my mother's stallion. They have to kind of warm him up though or he won't allow it. He gets to play some chase and then they will stand together. Local truckers used to love coming by the place when he was in the front pasture which is by a highway. He would stand at one end and wait for them to start to pass and would run the fenceline playing chase. Nothing like seeing him run, slide, rollback and chase another in the opposite direction.
