Llamas

Llamas have a natural dislike of canines (domestic and wild dogs, coyotes, and foxes).  After the llama bonds with its herd of livestock, it takes over as a protector and leader.  Llamas become aggressive only if a predator advances toward their new family group.  Llamas show aggression by chasing, biting, and kicking.  Guardian llamas can stomp to death a canine that will not retreat.
