Blue-Eyed Wolf

Charge: If the wolf moves at least 20 feet straight toward a target and then hits it with a claw attack on the same turn, the target takes an extra 1d8 slashing damage. If the target is a creature, it must succeed on a Strength saving throw DC 14 or be knocked prone.

Keen Hearing and Smell. The wolf has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. The wolf has advantage on an attack roll against a creature if at least one of the wolf's allies is within 5 feet of the creature and the ally isn't incapacitated.
