I got a puppy dog of Labrador Perdiguero a month ago when he was 3 months. My dog (sidekick) since going to the door but no scratches to let him know that he has to do his business. If we don 't let him out in time to runoff and that makes their business in my home. This is my 1st puppy so I do not know what to do. If you know anything that satisfies me out. Thanks for your time and concern.
