The arctic wolf is a subspecies of the grey wolf that I have written about before.
Arctic wolf (Canis lupus arctos) howling in the Toronto Zoo.
As such the arctic wolf with its bone chilling howl is technically the same species as your dog. The arctic wolf in the picture above lives in the Tundra Trek exhibit of the Toronto Zoo. In warmer whether it was just sleeping all day, but now that it is finally cold it started to feel like its normal self again.
