Cool looking dog. There seems to be a heavy yellow-ish color cast to the image though. It is easily corrected in photoshop by:

Duplicate layer.
Filter> Blur > Average (this will give you a solid color layer over the original).
Add Levels adjustment layer
Click on the Middle gray dropper, and click on the solid layer.
Turn off visibility of the solid layer (leaving only the BG and levels layer visible.
Then you can reduce the opacity of the levels layer to taste.

With your permission, I can download one of these pictures and show you the results if you like. . .
