Would this be okay?

So im thinking about creating a character whom is a hairless canine, yes it is a thing (along with hairless horses, cats, skinless frogs, hairless apes, and in some rare cases birds can be featherless) But i was wondering if this would be possible. If its, he/she would have to stay in a warm place bc..well it has no fur. In the actual animal kingdom hairless animals are noticeably weaker than normal animals and its harder for them find a mate and reproduce so this will probably play a large factor in the characters actions and health. Would this be okay?
