Wolves are predators and live in many regions. Wolves are social animals that live in groups. One on one, an armed dwarf will likely win with minor injuries, but if a pack gangs up, the hapless dwarf is in deadly trouble. A lone hunter can have trouble with wolves; she might spend all of her ammunition on a pack of wolves and then be killed by the survivors after trying to bludgeon them to death with her crossbow. If there are packs of wolves on the map, it may be advisable to team up hunters with trained dogs, or send out military patrols to deal with them instead. Strength in numbers, after all.
In Adventurer mode, wolves are common ambushers in random encounters that will occur across the world map. Even a pack of them should be easily dispatched by an inexperienced adventurer, provided he is suitably equipped.
