Try going out with him and giving him a treat the instant he finishes going to the bathroom and praise like crazy
This is a great idea. It seems as soon as you gave him more room he started going in the house. Maybe keep on him with the areas he is in,give him more boundarys and rules. One of my dogs is the same,he kinda figured it out now that we know he is just going out to possibly get a treat. So we eventually stopped giving him one all the time and watching when he went.
