One of America's favorites in the Toy Group is the Chihuahua, (pronounced sha-wa-wa). At maturity the Chihuahua may be only 5 inches tall and the standard requires that they be under six pounds. There have been adult Chihuahuas that weigh only about one and half pounds. This tiny dog is reputed to be the smallest dog in the canine world. There are two varieties, the long coat and the smooth coat and except for the difference in the length of the coat they are the same breed and there is no distinction between the two in their standard. A smooth coat has exactly that, a sleek and shiny close fitting coat with a well furred tail. The long coat has fringes of longer hair around the ears and neck and feathering on the legs, tail and the breech or "pants" on the rear legs. All colors are permissible. The Chihuahua should have a "domed head", rounded skull and large eyes, very expressive. The ears are erect and in proportion to the head.
