Push and Bite

Feats

Once per round, when you attack an enemy adjacent to your animal companion with a ranged weapon from the bows, crossbows, or thrown fighter weapon group, you perform a bull rush combat maneuver with a +4 circumstance bonus, using your Dexterity modifier instead of your Strength modifier to determine your Combat Maneuver Bonus. If this combat maneuver is successful, your animal companion expends an attack of opportunity to make a melee attack against that enemy and automatically hit them.
