Dogs that smile
Have you ever had one that did, or seen a dog smile?

My last dog was the only one I've ever had that smiled. Her grin wasn't quite as big as this guy's, but it was equally cute.
She only did it when she thought she'd offended me. Like in the yard (well, patio) at the fence if I walked up and she started barking at me like she would a stranger. It was like she was saying "Oh my word! I'm so, so terribly sorry, didn't recognise you. Forgive me, pleeeease??"
