The Xoloitzcuintli is a rare, exotic-looking and ancient breed. While some do have hair, many are hairless, a bonus for allergy-sufferers. They are loyal, tranquil and alert, and make good watchdogs. They're also ideal companions for an owner who is looking for an active canine friend. Xoloitzcuintli puppies need consistent training and structure. They're happy to live with other dogs and kids and also do fine as an only dog. With exercise and attention, they're trainable, cheerful pets.
