A Chiwawa That Thinks He's Super Dawg

I went for a walk along the river today with my dog (alsation/collie) called Boo and the girlfriend bought her new Chiwawa called Coco.
I got some great shots of the afternoon with both scenery and dogs but thought I'd post this picture of Coco running after my Boo.
This picture has not been shopped in anyway. I used the continuous shoot setting and this is one of the fabulous results.
