SFVS’s Sophia Yin, DVM, MS (Animal Behavior) was quoted in a recent article in “The Dog Daily” about dogs and howling: A Dog Howling Primer. The article discusses why dogs howl in the first place, along with some of the more “prolific” howlers (“hound dogs or Northern breeds, like Siberian huskies or Alaskan malamute”) and steps dog guardians can take to curb howling if necessary.
As far as why dogs howl:
“While less research has been done on dog howling, researchers believe that dog howling is a throwback to wolf heritage and that howls also have a variety of meanings.” …
“Other research has found that dogs have distinctive barks, and the same is likely true of howls. ‘With wolves, the thing about howling that makes it different from barking is that it’s not only longer but more musical in tone,’ Dr. Yin says. ‘It can be carried farther and carry more of an individual characteristic.'”
