Chihuahuas are miniature companion dogs. The breed, like others, has standards and characteristics. Chihuahuas are recognized as the smallest dogs in the world and were bred in Mexico.
Body. The Chihuahua is characterized by a square body, but in bitches the breed standard provides for a slight lengthening of the body. A dog of the breed must have a compact build. The body must be slightly elongated in relation to the height at the withers.
Head. It should be strongly rounded and apple-shaped. The head should be without fontanelle, but slight is allowed. The ears are erect, wider at the base, slightly narrower and rounded towards the edge. The transition from forehead to muzzle in the breed is clearly pronounced, this is due to the strong rounding of the first. The Chihuahua's muzzle is short, wider at the base and narrowed towards the nose.
Lips should be pressed together, dry. The Chihuahua's eyes are large and round by the standard, but not protruding. They are dark, but light is also possible. The bite of this breed is either scissor or straight.

Chest. In a Chihuahua dog, it has a deep and wide shape, the ribs are rounded. The chest reaches the elbows, but the shape of the barrel is unacceptable.
