I'm not an expert on these dogs, but I do know a little about them. There are 2 varieties - the hairless and the powderpuff. The powderpuff has hair all over, where as the hairless has hair on it's head, feet, and tail.
Before you consider getting one, you would be wise to read up on them. They are somewhat of a high maintenance dog and can develop many skin problems if not cared for properly, and they are notorious for having teeth problems also.
Good luck if you decide to get one - and of course if you do - we would love to see some pics.
