Do You Think this Dog is Smiling or about to Bite someone?

It's about that time for Halloween costumes to come out.  Isn't that exciting?  I don't think this is a costume though.

We are having a difficult time telling if this Dawg is about to chomp somebody's leg off or he is just saying "Cheese!"

Whatever you think, I still think Dr. Theriot at Theriot Family Dental Care is doing a great job on that Dawg's teeth!

So what do you say?
