Very cute dog (I love pugs), but truthfully Stacey these are just family snapshots. In my opinion, all 3 need to be cropped tighter, and your puppy is in awkward positions in #1 and #3. You also cropped off his legs in #3. For me, the best one is #2 if cropped tighter. Keep shooting!
I think shooting from a lower perspective and having less stuff in the background (concrete blocks) and shooting more wide open would take these shots up a notch.
