Hmm, I thought it was proven to be true...?
in the 70's one city stopped getting donald duck in favor of some sports magazines, which led to some angry people calling the congressman behind that "the man who DENIED donald duck from us" After which it was a case of bad translation and noisy phonelines.
But back to topic, i think the good doggy needs something to give it a bit of an edge. Like fry suggested, give it some fur and maybe a really rad and messy haircut. Chest hair is a must as well. The mouth area has some hard to read details, mainly the left side of his jaw. Some bits and pieces of clothing still hanging in places could add some detail and the green shirt looks a bit lake bodypaint rather than shirt, so stretch the shirt over concave areas rather than constantly following the surface shape.
Other than that, it looks really balanced and the pose seems comfortable for a werewolf. Looking good so far.
