Do wolves bark?

Wolves do not bark like domesticated dogs; however, they make a barking vocalization that resembles either a shrill yip, or a brisk huff, when alarmed or agitated.

Barking is a short-range means of communication for wolves, and they are reserved and difficult to observe in the wild, so people are not likely to hear a wolf bark. A wolf will bark to intimidate another wolf, or warn members of their pack when under the threat of predators. Other short-range vocalizations of the wolf are growling, which is used to exert dominance, and whimpering, which is a sign of submission or a friendly greeting.
