I agree with Pete. Although I'm going to say it needs a smidgen more contrast, just so I can use a cool word too.
What really makes this a good shot is the "dog's eye view" down low angle. Very nice!
You've got a good thing going here, EoI. There's a local pet group here that coordinates with the animal shelter and radio station to put together a dog calendar that helps raise money for the shelter. It's a huge seller, and I see that calendar up all over the place.
