Whyyyyyy is it licking it's lips?
I can only think of three reasons and I don't like the third.
A:It's got in a battle and it's licking blood off it's lips.
B: It's seen a juicy steak It really wants to eat.
or C: It REALLY wants it. (if you know what I mean.)

I'll try not to focus on this and instead focus on the fact that the artist gave it an oddly canine face.
