I use to guide back in the 80' s here in British Columbia,back then it was custom to tip $100 (which was a days wage) as far as i know the cook wasn' t tipped that i know of.and the guide' s themselves did all there own wrangling,also that was for a 10 day hunt.but i would say it all depends on how hard your guide works for you.
hope this helps some.........good luck
