Winter wolves can speak Giant and Common.
Winter wolves typically hunt in packs. Their size, cunning,
and formidable breath weapon allow them to hunt and kill
creatures much larger than themselves. A pack usually circles an
opponent, each wolf attacking in turn to exhaust it. If
they're in a hurry, white wolves try to pin their foes.
Breath Weapon (Su): Cone of cold, 15 ft., every 1d4 rounds;
damage 4d6, Reflex half DC 16. Winter wolves can use their breath
weapon while biting.
Trip (Ex): A winter wolf that hits with a bite attack can
attempt to trip the opponent as a free action without making a
touch attack or provoking an attack of opportunity. If the
attempt fails, the opponent cannot react to trip the winter wolf.
Cold Subtype: Cold immunity; double damage from fire except on
a successful save.

wolf has a +4 racial bonus to Wilderness Lore checks when
