CharlieGodammit is Norwegian Farm Dog (Buhund) and American Husky but his dominant traits are Buhund. By nature, he is a herding dog. Get 3 or 4 people in the backyard and he nips and pushes them into a group and then tries to keep them together.
In the house the only thing he has to herd is the 2 Evil Cats.
He has yet to see the futility of that exercise.
