Very cute pooch. If (s)he's cooperative enough to do it again, try playing around with the DoF a bit. It would be cool to see the nose or eyes perfectly in focus and everything else blurred.
Also, since you don't want to blind your pooch with flash, you might want a higher ISO if possible (since animals don't often cooperate when posing for photos)
I wish I could come up with a loldog addition, but am a dummy ATM.
