The Chihuahua is a tiny dog with an apple-shaped head and a short pointed muzzle. It has round, large, very dark eyes, sometimes dark ruby or luminous in color. The trademark large ears should be held erect. Puppies have a soft spot or "molera" on the top of the skull. The bone usually closes the gap by adulthood. The body is cobby (stout), longer than it is tall, and the tail is sickle-shaped - curled over the back or to the side. Besides the common short-haired variety there is also a long- haired type. Colors include fawn, sand, chestnut, silver and steel blue, but any color is accepted, including black & tan and parti-color. The dog is more robust than he looks, with a level back, and legs coming down straight and square.
