The Chihuahua holds the distinction of being the smallest recognized breed in the American Kennel Club, yet few dogs pack more personality into their frame. Named for the Mexican state of Chihuahua — where ancestors of the modern breed were discovered in the 1800s — this breed has been an AKC fixture since 1904 and today ranks among the top 30 most popular breeds in the United States. In US cities from New York to Los Angeles, the Chihuahua is as much a cultural icon as it is a companion dog: easily carried, intensely loyal, and possessed of a self-confidence that makes them blissfully unaware of their own size.
The AKC recognizes two coat varieties — the smooth coat and the long coat — with identical breed standards otherwise. Both are shown extensively at Westminster and AKC dog shows across the country. American breeders have developed strong health testing protocols through the Chihuahua Club of America, making OFA patella and cardiac evaluations standard practice in responsible US breeding programs.
