Listen. Wolves communicate through sound, smell and body language. Howling has a number of functions – it calls the members of the pack together and plays a large part in socialization and bonding.
Short, rough barks signify fear or a threat, and serve both to warn other pack members and to scare away intruders. Growling is a sign of aggression while whining is used to make contact.
Wolves have a well-developed system of body language to show their moods and position in the hierarchy. Scent is used primarily to mark territory boundaries. The alpha pair in the pack may also use scratch marks to emphasize the limits of their territories.
