I don't know if I could beat this scene for happy, Frank. I had to laugh when I first opened it because my dogs usually have this same smile/goofy grin on their faces. Dogs are not subtle, they have no deceit, no ulterior motives. They're just happy hangin' with their humans and this image of yours captures that perfectly. It's just flat out fun.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
