In case anyone tells you wolves don't bark, here is proof that they can. They don't usually, it's mostly as an alarm. Which I guess is why dogs bark too.
The one barking is in the center of the video, and he was a little agitated at a new staff member doing some weed whacking. We also have him and his sister separated from the two puppies (recovering from a vet visit), so he was probably trying to warn them too.
