The support ability of an animal companion says that they will inflict d8 damage if their Ranger/Druid/friend successfully hits something that they can reach; is the animal companion's strength bonus added to this damage?
Your bear mauls your enemies when you create an opening. Until the start of your next turn, each time you hit a creature in the bear’s reach with a Strike, the creature takes 1d8 slashing damage from the bear. If your bear is nimble or savage, the slashing damage increases to 2d8.
This is NOT a strike and no mention of it dealing strength mod damage is listed.
