Do llamas protect against wolves?
Llama's can be successful guard animals since they naturally dislike canines.
When the flock is in danger they become aggressive towards coyotes, wolves, dogs and foxes. When protecting the flock, llamas are alert and may alarm call and position themselves between the flock and the trespasser.
Research suggests the use of multiple guard llamas is not as effective as one. [no idea which research

]
