Thanks again everyone.
Zoom, some of them were just taken on the action setting because I was lazy, and others were taken on either the M or S settings and then I adjusted the ISO and aperture as needed.
SmexyPibble, my camera is a Nikon D40. Charlie isn't hairy for a Lab I don't think... at least, not compared to most of the Labs around here. She prefers to spend a lot of her time outside though for some reason, so maybe that's why her coat is thicker (and lighter in colour).
SkKi, thank you. She seems to have really muscled up in just the last couple of months or so, though it's often hard to tell just by looking at her because of her coat.
