How can I get my puppy to tell he that he needs to go potty? My scotti is 5 months old now and is pretty good about going potty outside but I think it is me that is trained, not him! I am the one trained on a schedule of taking him out. He'll just go in the house never indicating that he has to go (I would like him to start waiting longer than every hour to go potty). When will he start letting me know when he has to go? And, is there any way to train him to go to the door as the signal that its time to go potty?
