the crested have 2 styles one is the powder puff hair all over the body looks like just what they call it a powder puff then theres the hairless they have hair on their heads tail and legs some will have a few strands on the body the hairless have to use sun screen in the summer as they will sunburn they will get black heads in their pores and some have skin problems you can breed two hairless and get a powder puff in the litter. a friend of mine ownes 5 of them they are really neat little dogs used in obe training and agility great little therpy dogs. one of hers is a sevice dog he goes everywhere with her. hope this answers your question. they are really neat.
