The Chihuahua, a companion dog of diminutive size, has been known as the Chihuahua Kortaar, the Smooth-coat Chihuahua, the Chihuahua Langhaar and the Longcoat Chihuahua. It also has been called the Mexican Dwarf Dog, the Ornament Dog, the Raza Fina and the Pillow Dog. Chihuahuas have a plucky, almost terrier-like temperament that serves as an effective alarm system. They are alert, bold, feisty little dogs with saucy expressions and playful dispositions. Chihuahuas are most famous for their tiny stature, which arguably makes them the perfect portable “purse dog” or “pocket pet.” They should not be underestimated because of its size. This is a highly intelligent and athletic breed. Chihuahuas that are not properly socialized can become snappy towards children and strangers, and their delicate bone structure requires special attention so that they are not injured by jumping off of high places or being hurt by rambunctious children. The Chihuahua was recognized by the American Kennel Club in 1904, as a member of the Toy Group. They are consistently ranked among the top ten in popularity of breeds recognized by the American Kennel Club.
The Chihuahua is not to exceed 6 pounds and ideally stands between 6 and 9 inches at the withers. They come in both smooth and long coats, which are judged equally without preference. Their tail should be full and long, resembling a plume, and feathering on the feet and legs is preferred. Chihuahuas have talon-like feet with long, curved nails. Their coat is easy to care for and can come in any color. Their upright ears should be cleaned regularly. The Chihuahua tends to shiver when cold, excited or nervous.
