When Milo was a puppy I had him on a schedule where I would take him out every couple of hours. In the house he had no collar or harness on and I would put it on him at the front door before we went out. After a little time he just started going to the front door and pawing at it to let me know he has to go out. They are very smart animals if you watch your puppy very carefully you should notice a change in behavior before they pee or poop in the house |
