OK, that last one is really nice. Isn't it hard to get the lighting right on black dogs? I have the same problem with my cat, Ebony. All the facial features disappear into the back/chest/shoulder area. That is why I like the last one, as you can see more features on the black dogs.

Corona is the white one, eh? I LOVE that 3rd photo - she looks like she is checking out if the sign is edible, hehe.
