Who's a happy dog?

This photo a redditor posted of his dog actually kind of drives me nuts. Intellectually, I know that's a regular dog with a rubber lips and teeth chew toy in its mouth. I can even see its teeth down there at the bottom. But no matter how hard I try, I cannot not see a really, really happy dog with a big goofy smile on its face.

Which, in the grand scheme of things, is not a terrible thing to be unable to un-see. There are certainly creepier dog-themed illusions.
