I looked at your thread and YEAH, I definitely think you have a white balance issue. The whitest white is keying off the center of your subject area and not taking the whole photo into account. Your dog is black and the tones within him, under normal balance settings would be rather dark. But yours is open with alot of detail (too much). If you think about a tonal curve in simplistic terms if an area that should have a setting of say 50 (just an arbitrary number) gets a reassignment of 30 (again, just a made up number - no real relevance to your camera or digital imagery), then what was originally a 20 becomes a 0 (nothing). If your dog was black in the darker tones that would be expected, then there would room on the curve to hold areas of lighter tonality. Does this make any sense to you??? Sorry if I not explaining well!!!
