One tool that you might want to look at for correcting the lighting in this picture would be the tutorial on shadows and highlights on this website. Most notable is the blown area of highlights under the eye where you lose the detail of the fur. Also, you lose detail in the shadow areas.
Another thing you might want to look at would be the lighting in the sense of how to shoot other pictures.
It is often said that if you have a strong direct light, try to place something that either blocks or diffuses that light in it's most direct path.
Most people use cloth screens or bouncecards. Some use a bouncecard to lighten the other part of the subject, largely preserving the special quality of the light they saw in the first place, others would block the light to soften it's effects. In this picture, the result would be that the catchlights in the eyes would be changed, allowing more detail of the iris, rather than of the catchlights themselves. Notice how it is easier to see the eye that is behind, but it is out of the depth of field.
If you balanced your light differently, I feel it would allow you to expose a little differently and get more detail in the foreground eye and balance your shadows a little.
I am by no means an expert in using these techniques, but that is just what I gather from the basic principles.
i hope it helps.
