The people are still asking, is there is possibility that people who are allergic for hair of dogs an cats could have f.e. Perro Sin Pelo del Peru. There is no unambiguous answer for this question, because also hairless dogs are loosing all the time little pieces of cuticle, and allergy is bringed not by hair but by dog cuticle or even by his spit. So you can't exclude situation, when the allegry will also develop after contact with hairless dog. If you are alergic for the hair, the hairless dog is an excellent chose for you, but only why to check it is to made a contact directly with such animal or by examinatin a sample from dog by your doctor.
