The Budweiser Clydesdales are a group of Clydesdale horses used for promotions and commercials by the Anheuser-Busch Brewing Company. There are several "hitches" or teams of horses, that travel around the United States and others that remain in their official homes at the company headquarters at the Anheuser-Busch brewery complex in St. Louis, Missouri, or at Merrimack, New Hampshire. At St. Louis, they are housed in a historic brick and stained-glass stable built in 1885. There are eight horses driven at any one time, but ten horses are on each team to provide alternates for the hitch when needed. Assorted Clydesdales are also used as animal actors in television commercials for Budweiser beer, particularly in Super Bowl ads.
