IMHO. The one with himon the beach looked the best. Very cute dog though.
If I may offer a suggestion, When Framing the Picture, Try to not have any Background Lines Going through the Objects Head and or Body, for example a Hallway Door Frome interjecting through the Dogs head, Or a Kitchen Table going through his Body.
The reason why, is Sometimes, It builds up Tension , and Distracts from the main Object you wish to photograph.
