Greyhound Poops In House And Eats Alot?

I have a 2 year old greyhound that is potty trained but likes to poop in the house. How do i get him to quit this? he also sometimes pees. I know that he isn’t trying to show dominance due to his submissiveness but am at a loss as to how stop this issue. He also goes past child gates and gets into food while we are gone. I tried shutting him in a room and he clawed through the door. we like the dog and want to keep him but need to get rid of these issues to keep him.
