Looks pretty good. I'd try to boost the brightness of the shadow range a bit, to help define the eye in the black fur.

Also I find a lot of dogs eyes come out very, very dark, and it doesn't look good. You should be able to do a masked brightness change to the eyes in just about everything (Photoshop, Photoshop Elements, GIMP, Lightroom, but not DPP). In Elements I do this as an adjustment layer. First I crank it up really bright so I can see where I'm painting the mask, then I can just drag the slider around until I feel it looks good.

But, yeah, overall, good job!
