In general, llamas don't like canines. One's own llamas with one's own dog may be an exception but, personally, we keep ours separate or very, very close and under our control. But then, we have a group of llamas and only one dog...
Llamas do well as guards against coyotes and could even work against wolves. But in the anecdotes I've read, llamas don't handle pack aggression well. Hence their general success against coyotes and their general failure and fatality when facing wolves.
