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.
howling is just one the things many dog breeds have lost the need to do. in the wild wolves don't bark past puppyhood, and howling is done to rev up the pack before a hunt. domesticated dogs lost the need to howl as they do not go on long hunts like their ancestors but kept the bark instead.
