The Chihuahua is a balanced, graceful dog of terrier-like demeanor, weighing no more than 6 pounds. The rounded “apple” head is a breed hallmark. The erect ears and full, luminous eyes are acutely expressive. Coats come in many colors and patterns, and can be long or short. The varieties are identical except for coat. Chihuahuas possess loyalty, charm, and big-dog attitude. Even tiny dogs require training, and without it this clever scamp will rule your household like a little Napoleon. Compact and confident, Chihuahuas are ideal city pets. They are too small for roughhousing with kids, and special care must be taken in cold weather, but Chihuahuas are adaptable—as long as they get lots of quality time in their preferred lap.
