It's actually based on their genetics. They're just like that. They are very friendly. They are hairless muscular dogs that come in a few different sizes. They look different than any other dog i've ever seen. No, they don't feel weird. They get cold in cold temperatures and in that case, need a doggy sweater. They are from Mexico. I don't think they are ugly, i think they are the coolest looking dog there is, but that's just my opinion. Their teeth are sharp, but not as much as other dogs. Their teeth aren't like knives or anything. Hope this answers your questions.
