This is Toxin, my mutated wolf that lives in the same world as my Wughouls and mutated dogs. This particular picture is actually part of a much larger piece I've been working on with the wardog Legend in it.
Toxin is supposed to be a temporary name, but it's stuck for years haha.
He is the alpha of his pack, however he is probably the most gentle other than the omega. He's very shy and quiet, his mate is the real leader. The green ooze seeps out of his mouth and eyes, and sometimes nostrils, when he feels intense emotions like excitement(portrayed in the image), fear, or rage(rare).

Not he does not have visible pupils, what you see here is a red reflection from an eclipse
