Originally, as the name suggests, from the United States, this dog is quite small and compact. It is quite muscular and has a bushy tail curled over its back. Its hair is thick and dense, on the level of the chest and less on the legs, it is very often white, but variances may occur. It makes a very good sled dog, fast enough and tough: take it for long walks; it is almost tireless! It will also make a good guard for your house, and a great companion for your entire family.
