Hairless dog

The dominant type is caused by ectodermal dysplasia as a result of a mutation in the FOXI3 autosomal gene.

[1] Dogs with dominant genes for hairlessness can pass their attributes to their offspring in natural conditions; that is, not under the control of humans.

[citation needed] This type of genetic structure is said to be homozygous pre-natal lethal for the dominant gene.

[3] The Chinese Crested Dog's coated variety is called a "Powderpuff" and is a recognized type.

The coated variety of the Xoloitzcuintle is recognized as a valid type for conformation showing with some registries, including the AKC.
