What a beautiful dog
I really like the shots. Love the dof in the first shot and the second one I think is rally well-framed and sweet. Someone who does portraits might have comments on the lighting, but it looks fine to me.
I'm not usually a fan of tight crops, but I do wonder about the first one and proportion of space above and below the dog. I can't decide if the extra space above her head works or not, but it's probably because I'm on my netbook right now and the screen is too small to see the whole picture at once. What I did notice, though, when I was trying to look more closely at that first shot is that her paw is sitting right on the seam of two planks of wood and it looks almost like something is stuck in her paw. The seam also shows kind of brighter that the rest of the floor so it draws the eye down a little, especially since it's also next to your watermark. I'd say a bit of cloning?
Those are minor details, though.
