Canine packs hunt larger animals using a technique called relay hunting. In this method, one member of the pack chases the prey for a while, then another takes over. Each member of the pack takes a turn in chasing until the prey becomes exhausted. The canines then immediately surround the prey and move in for the kill, often attacking from behind and injuring their victim. In this way, canines are able to take on very large animals, such as bison.
