As show in the attached image (left character window, right passive skill tree) the +Companion Dodge Rating, is NOT REGISTERING in the character window. I am not sure if the game factors this +doge rating during play.
However, if I equip a +Companion/Minion Dodge Rating gear, then the total Dodge rating appears in the character windows. For example, I have a +20 Companion Dodge Rating from my passives. If I equip a +100 Companion Dodge Rating, ONLY THEN I see the total 120 in the character window. When I am not wearing a +Companion/Minion Dodge Rating gear, the I see zero in the character window.
It’s because the character sheet shows “minion dodge” and the passive is for companions. Companions being a subclass of minions, it seems appropriate the character sheet does not show it.
Sabertooth for exemple is a minion and a companion.
Vines or bees are minons but not companions.
