Chihuahua's
Coat
Chis can be born with either short or long coats. This variation in coat type is a unique fact about Chihuahuas. The short-haired Chi requires little grooming but will need a wardrobe to help protect her from catching chill. The long-haired Chi does need regular brushing to keep her coat free of mats and tangles.
