What are you feeding him?
Maybe a food like Innova with a brown rice base and scheduled feedings will really aid you.
Have you leashed him to you to stop house pottying?
I had to leash my marker to me to catch him every time-in our house we only used belly bands for later when wen out places to prevent marking in those places-retirement home, pet boutique, friend's houses etc.

Mine was a barely (estimated) 5 months old, pup mill rescue who would pee or poop literally next to his bed and lay there with it-it took about a 6 months of constant work to aid in him using a potty pad (litter box at first) to get him to potty in the bathroom, then about another 6 months to teach him to potty outside...a lot of effort, training, positive reinforcement, making a potty spot outside, and a lot of cleaning...
