  In the stack pic his back feet are under him. Stack him so that the front heels are in direct line with the withers and the rear pasterns are perfectly straight. That should bring the shoulders up a bit and the rear down. He looks a bit low in the shoulders but I thinks it's the stack. If you get a pic of a correct stack (not easy with puppies) please send another pic. Alot of it is maturity and practise.
