Yes, a Miniature Shiba Inu does exist. Miniature Shiba Inu is also referred to as Mame. They're bred intentionally to be smaller by about 35% to 50%. However, breeding this size of a Shiba Inu is frowned upon by responsible Shiba Inu dog breeders. The practice of producing Miniature Shiba Inus is done by unscrupulous dog breeders who starve the puppies so they won’t reach their normal sizes in adulthood.
