Ancestry/Breed. Sometimes a dogâs propensity to howl is genetic. Certain dog breeds tend to howl more than other dog breeds; maybe itâs the olâ wolf in their ancestral family tree. Malamutes, Eskimo Dogs, Huskies and many hound breeds seem to be genetically predisposed to howling. Some breeds actually just enjoy howling like humans enjoy karaoke.
All species of fox have a pretty wide variety of vocalizations, just as dogs and cats do. It's simple to reduce, say, a dog's vocalizations to bark, but as any owner knows, dogs can yelp, whine, howl, growl, and make all kinds of other sounds. Foxes aren't quite as varied in their vocalizations as dogs, but they're still capable of making lots of different sounds.
