Some llamas make excellent livestock guardians, protecting herds against dog and fox attacks. Highly intelligent, llamas can distinguish between possible and imminent threats. They have a natural wariness of canines and although they will become used to the family dog, they will become aggressive toward a predator advancing on a family group.
A confrontation between a llama and predator usually results in the predator’s retreat. Llamas have been known to stomp foxes, coyotes and predatory dogs to death as well as herding flocks of livestock to protected areas. However, despite this ability a llama is no match for a pack of marauding dogs.
