How Does a Chihuahua Become Hairless?
Purebred Chihuahuas can be born without fur and can live their entire lives without developing more than a few hairs on their chins. However, it’s extremely rare for purebred Chihuahuas to be hairless. Chihuahuas can carry a recessive hairlessness gene, but a dog would need to inherit the recessive gene from both parents, which is quite rare.
More commonly, hairless Chihuahuas are mixed breed dogs, usually with an ancestor who carries a dominant hairlessness gene like a Chinese Crested dog, an American Hairless Terrier, or a Xoloitzcuintli or Xolo, pronounced SHOW-low. These dog breeds are bred to be mostly hairless and can pass this trait on to their Chihuahua mix offspring.
It is very difficult to purposefully breed a hairless Chihuahua since it would require purposeful testing for a dominant hairlessness gene, and then breeding that dog to a dog without a dominant hairlessness gene, and their offspring would only have a small chance of being hairless. Two dominant hairless gene dogs should not be bred together, since puppies that inherit the double dominant gene are not viable and rarely make it to full term.
For this reason, most hairless Chihuahuas are from accidental cross-breed litters, or from unethical backyard breeding programs.

Basic Breed Info
Purebred hairless Chihuahuas are no different in temperament or size-wise than their furry cousins! The only true difference is in how you treat them in extreme temperatures. In the sun, hairless Chihuahuas run the risk of getting sunburn and may be at a higher risk of developing certain cancers. In the cold, hairless Chihuahuas need clothing to keep them warm, since they lack the protection of fur.
If your hairless Chihuahua is not a purebred, its temperament and size will be less predictable, but you’re still guaranteed to have a great dog!

Are Hairless Chihuahuas Recognized by the AKC?
When a purebred Chihuahua is born without fur, it is considered an AKC dog if the breeder is AKC registered, but is not eligible to be shown in the ring as it is not a standard coat length or color. When a Chihuahua is hairless because it has been mixed with another breed, it is not considered an AKC dog, since it is not purebred by an AKC-registered breeder.
