when potty training your dog, i recommend that you never, leave him alone in case that he goes where it's not wanted to instead of the place you want him to pee/poo. Also you should keep a constant eye on your dog in case he takes anything special and breaks it or eats it. Also be careful with cables, such as the tv room, he might get interested in the cable and starts chewing it, which will costs your pet's life and your tv's certainly!!!!
