Čopori vukova su bili uvelike dio njihovog sistema tako da ih se toleriralo na granici krda i tako familijarni ti prirodno vješti lovci noseći vučju kožu na leđima mogli su se kretati uz bizone ne izazivajući stampedo.
The wolf packs were so much a part of their system that they were tolerated on the fringes of the herds and so familiar that skilled native hunters wearing wolf skins on their backs could move among the buffalo without provoking a stampede.
