Rez dog

Rez dog (short for reservation dog) is usually a term for outdoor, stray, and feral dogs living on Indian reservations in the United States and Indian reserves in Canada. The term has taken on many connotations, and has to some extent become an emblem of and metaphor for reservations, reservation life, and Native Americans in general. For example, a "rez dog" may refer to a Native American resident of a reservation.

The distinction between a reservation dog and American dogs in general is often seen as emblematic as the difference between First Nation and majority culture way of life. Untended dogs roaming First Nation reservations and other rural First Nation communities cause problems that the communities must deal with. They are generally thought of as mixed-breed and unsupervised.
