`  Support  There is a difference between oficial terms and terms that are used in common language. In al structures all over the world concerning dogs, also in Wikipedia, FCI rules are the rules to look at. In an official, worldwide encyclopedia, my bet is, to use the mostly used oficial name, worldwide. Which is Mexican Hairless Dog.  On the other hand, the name Mexican Hairless can lead to confusion. Mexican Hairless does relate to many other things as only dogs. Imho an encyclopedia should use terms that not lead to confusion.  If we look at the origins of the word, that derives from Mexico the names used for this breed are ``Xoloitzquintle`` or Perro Sin Pelo de Mexico``. The latter means just Mexican Hairless Dog. It isn't ``Sin Pelo de Mexico``.  Should we look to changing the name in  or Xoloitzquintle or Mexican Hairless Dog?`
