In howling along with music, not only is your pooch not attempting to bother your ears, he's not trying to show off his impressive soprano singing skills, either. The howling, however, may be traced back to your dog's wolf heritage. Wolves in the wild often "converse" with other members of their packs by howling. Not only is howling a means of gathering everyone into a single spot, it also can be a simple way for wolves to celebrate the oneness of the unit. Even if your dog has been living indoors with humans for his entire life, you can't always shake the wild instincts bestowed on him by his ancestors.
