Predator?

nah, but the alpacas seem to think so. What are they are looking at?



Just Quinn:



But actually a dog can be a big deal, most injuries to alpacas are caused by neighborhood dogs that get loose. So it's good that a dog puts the alpacas on edge. Quinn is pretty harmless, given his personality and the fact he's so much smaller than the alpacas (see Snowstorm looking down at Quinn):



But not all dogs are harmless. Alpacas have been known to stomp dogs, though there are other cases where the dogs attack and injure (even kill) alpacas.
