the hairless are more prone to tooth problems, they have primal teeth as it was descirbed to me, they look more like tusks than normal canine canines...
these are usually the first to fall out, and as i said the hairless tend to be more prone to early tooth loss.
all toy breeds however are prone to teeth problems.
they are also prone to skin problems like zits and drynes, and prone to wool alergies.
sunscreen and sweaters are 100% musts thoughout the year.
perosnality wise they are terriers! there definatly lap dogs but not as frufru as people think, they love to play and run and are just clowns.
i was looking into getting a hairless crested, there sweet dogs if you can deal with the extra skincaire routein.
