If you are truly committed to him, then why not just buy an ex-pen or baby gate to restrict his access to the door in the dog room?
Dogs and puppies are hardwork and if you have decided that you are just not up to that committment then it is best to rehome him now while he is still young and desirable. If you are truly interested in keeping him there are many people on these forums who work and successfully own basenjis. If you are going to place him please contact BRAT. They carefully screen their adopters and if at some point in the future he needs to be rehomed again then they will be there for him for life.
