I have a dog that is part wolf, part Siberian Husky. We have a big backyard, so he loves it outside. My bedroom window faces over the backyard and everynight, he howls and I swear, after all these years of listening to him howl, I can understand what he wants or what he is saying. His tone changes, the length changes, there are different inflections. It’s beautiful. I’ve never heard a wild wolf howl, though I don’t imagine it would be any different.
