Been down that road a bunch of times with puppies. This time when we got Abby she was ten weeks old our rescue dog Whitney immediately mothered the pup and taught her to scratch at the door to go out and in and where to go potty in the first day. Never had an accident in the house Whitney did all the training and was a chew toy for the pup.She has gone on the patio a couple of times. Our last 2 dogs were rescues that were already potty trained. We are a little tired from the training, she is catching on pretty quickly though.
