Wolves have the following traits:

Scent (Ex): This ability allows a wolf to detect approaching enemies, sniff out hidden foes, and track by sense of smell. See Special Qualities for more information.

Trip (Ex): A wolf that hits with a bite attack can attempt to trip the opponent as a free action (see page 152) without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the wolf.

Skill Bonuses: Wolves receive a +4 species bonus on Survival checks when tracking by scent.
