|The hairless quality is due to the presence of a hairless gene… the symptom of that gene is lack of hair on the body of the dog. This gene can also attribute to the lack of some teeth with lower k-9’s leaning slightly forward in some mouths. There can be differing degrees of lack of hair on the body. Some hairless dogs have a little hair on the top of the head, the tip of the tail and on the lower leg and foot. Others have hair that has to be groomed to make the hairless appearance. However having no body hair as in a true hairless: Hair in all the right places and little body hair as an ideal hairless: lots of hair as in the hairy hairless: The hairless puppy is totally hairless at birth and carries the hairless gene as well as the puff gene .. The hairless gene is what determines that it is a hairless puppy not the lack of hair on its body – that is just a symptom of the hairless gene. The hairless Chinese Crested is complete in itself it has a hairless gene and a powderpuff gene and does not need the Powderpuff for any reason. The Powderpuff can not improve the hairless qualities in the hairless puppy because hairless qualities are linked with the hairless gene and the Powderpuff does not have one. The Powderpuff CAN NOT produce a hairless puppy, it can only parent a hairless puppy when breed to a hairless mate and all the hairless qualities then come from the hairless parent. When having two hairless parent you have two hairless gene pools to pull from and in this way you can improve the quality of the hairless puppy.
