Is this "Portrait of a King" more appealing in Black and White or Color? I'd love your opinion!

Last week I photographed for a family comprised of two dogs, two cats and their two very kind owners here in Austin. After the session I created a few images of their fun-loving neighbor dog, "King" through a hole in their fence. The hole, I was told, was generously started by King some time ago. My clients decided they would just frame it out and let the dogs talk amongst themselves more easily. (And let me just say, they like to talk!) And so, as I was editing the session from last week I decided to play around with one of the images of King as a more fine art image. I took this photograph just "because." Sometimes we creative types think we can hear photographs asking to be taken and this was one of those scenes. It seemed funny to me, but perhaps the image is a bit more dramatic? I'm playing with black and white and color and I am really not sure which direction I'd like to keep going with it...

I'd love your suggestions on a title for photo and whether it deserves color or black and white! Thanks.
