This paper explores the effect of peoples' association with guide dogs on h
ow they understand and feel about themselves and how they are regarded by t
hose with whom they interact. The concepts of personal, collective, and soc
ial identity are used to situate the discussion. Of central importance is t
he way working with a guide dog shapes public interaction and how owner' se
lf definitions and social identities are extended by being intimately invol
ved in the owner-dog team. (C) 2000 International Society for Anthrozoology
