The UK Kennel Club considers the two to be distinct breeds; mating between the two are not eligible for KC registration. The AKC considers Long and Smooth coated chihuahuas to be the same breed. Typically, the breed standard for both the Long and Smooth coat Chihuahuas will be identical except for the description of the coat.Both the Smooth and the Long Coats have their special attractions and are equally easy to keep clean and well-groomed. Also, larger breeding females are less likely to experience dystocia (obstructed labour). Many breeders try to breed Chihuahuas as small as possible, because those marketed as 'teacup' or 'tiny teacup' command higher prices.Chihuahuas occur in virtually any color combination, from solid to marked or splashed, allowing for colors from solid black to solid white, spotted, sabled, or a variety of other colors and patterns. Common colors are fawn, red, cream, chocolate, brown, mixed, white, and black. No color or pattern is considered more valuable than another.
