Pariah dog, also called pye dog, pi dog or primitive dog, refers to the feral dog of India. Pariah-type feral dogs are typically medium-sized and have yellow to rust-colored coats. A 2004 Swedish study of mitochondrial DNA found that dogs (Canis lupus dingo) in Southeast Asia are from southern China, not from India. Indian dogs (Pariah dogs) are C. l. familiaris.
The term used to be an epithet to the same extent that the word pariah could be used to denigrate as well as designate the lowest social caste of Indians, but is now used by kennel clubs with no negative judgment implied.
