They are all the same two dogs taken in the same photo session. They are all in the exact position I took the photos. All I did is layer in each exposure so that all the photos show at the same time (just the dogs). Some of the shots I was not sitting in the chair as I had to put the dogs in position and bribe them with a treat. One more dog on the far right would have made it look more balanced. I tried some shots outside the window but the dogs aren't tall enough.
