As we know about the blue vargul blighthound that is currently untameable, from I discovered, there are at least one blue skin. The other skin is not as bright and glowy. The one to the left is the one we know. There is a small difference to the glows.
Then we got the green blighthounds, again with two slightly different skins.
Finally, here are the skins I was talking about. They look very awkward but it does add a taste to these demon dogs. The near total black does make sense in a way.
