This is a cute shot and well executed. Strangely, I don't love it and I like animal photos. I can't quite put my finger on why. Maybe because I can't see the puppy's eyes? It might be the perspective; the way the puppy's body recedes directly behind it.
Very cute dog. Dog's do have some bad habits. I like the fact that you didn't go straight to a human habit like biting finger nails or smoking. Too many of those. Good Work.
