Ok, you need to go further back with your training, He needs to be leashed with you at all times. It will not be fun, but if you can do this and crate when you are gone, and give treats and praise like crazy when he goes outside. maybe vet check to be sure no infection in kidneys or bladder to be a cause. Take him out on a leash every day and don't bring in until he does the job. Keep gates up so he cannot get into bedrooms & bathrooms. And hate to say, but hang up the clothes and keep closet doors closed. Our B Kell, failed foster, did purposeful peeing on our bed 2 days in a row, not happy campers here, but we went back on the beginning training, and after a time he got with the program, but all rooms are gated now or the doors kept closed. It is very frustrating, I know this, but I do believe with work it will come about for you. At least the dog has not marked you, when we brought in a new dog, my old man Cory decided to prove who I belonged to by marking me when I was sitting on the couch! this breed is something else.
