According to the FCI breed standard, the most important aspect of its appearance is its hairlessness. The dog may have short hair on top of its head, on its feet, and on the tip of its tail. In Peru, breeders tend to prefer completely hairless dogs. The full-coated variety is disqualified from conformation showing. The lack of hair leads to a reputation for being easy to wash and for a natural lack of fleas. The breed does not cause typical allergic reactions to dog-sensitive humans because they lack the normal dog dander. Dogs should be washed from time to time to remove dirt and prevent clogging of pores. Baby cleaners are a good choice provided that they do not contain lanolin. Some dogs are prone to have acne or at least blackheads. The skin sometimes becomes too dry and can then be treated with moisturizing cream. Again, baby lotion without lanolin is a good product choice to soften and moisturize cleansed skin.
