ebbing howl and is probably, similarly to coughing, used to warn the puppies and members of the pack. Additionally, dingoes emit a sort of "wailing" sound, which they mostly use when approaching a water hole, probably to warn already present dingoes. According to the present state of knowledge, it is not possible to get Australian dingoes to bark more frequently by making them associate with other domestic dogs. However, Alfred Brehm reported a dingo that completely learned the more "typical" form of barking and knew how to use it, while its brother did not. Whether dingoes bark or bark-howl less frequently in general is not sure. The now extinct Hare Indian dog of northern Canada was not known to bark in its native homeland, though puppies born in Europe learned how to imitate the barking of other dogs. When hurt or afraid, it howled like a wolf, and when curious, it made a sound described as a growl building up to a howl. The Basenji of central Africa produces an unusual yodel-like sound, due to its unusually shaped larynx. This trait also gives the Basenji the nickname "Barkless Dog." Barking in other animals Besides dogs and wolves, other canines like coyotes and jackals can bark. Their barks are quite similar to those of wolves and dogs. The bark of a dingo is short and monosyllabic. The warning bark of a fox is higher and more drawn out than barks of other canids. There are non-canine species with vocalizations that are sometimes described as barking. Because the alarm call of the muntjac resembles a dog's bark, they are sometimes known as "barking deer". Eared seals are also known to bark. Prairie dogs employ a complex form of communication that involves barks and rhythmic chirps. A wide variety of bird species produce vocalizations that include the canonical features of barking, especially when avoiding predators. Some primate species, notably gorillas, can and do vocalize in short barks.
