hey everyone, my english bully is almost 4 months, he is housetrained for the most part but if we are in my room with the door shut for a long period of time, he will not ask to go out, he will just pee on the carpet, i know he is young and am not expecting him to ask to go out just yet, im just wanting to know if there is any way i can train him to ask to GO OUT, like scratch at the door or go to the door or something, thanks in advance. here he is by the way.
