Our 10 almost 11 week old puppy Penny just went out the doggy door, went potty, then ran back inside!!!!! She hasn't had an accident in the house for two days now and we have recently given her quite a bit of freedom although she has been under close watch. We have been taking her out every couple of hours to go potty during the day and once every three hours while during the night. It has been a lot of work but it seems as if it is starting to pay off. Our goal is to have her as a free roaming inside and outside dog. Hopefully she keeps it up!
