A Llama can easily kill a human.A friend had several that she used as guards to protect her other stock.I never trusted them.
Llamas are huge ! Not like!
They really don’t like canids (dog, coyotes) but ours were pretty agnostic about people. Never did anything aggressive towards people but would always chase the dog away even after years of him trying to make friends. Although they were never physically aggressive the spit like fiends when being sheared, I would be covered from head to to with green slime that smelled like a combination of vomit and death.
