Lexi is 12 weeks old and isn't fully potty trained. The key is to keep an eye on them at all times. I get mad at myself when I find a spot and I wasn't there to witness the event. This hasn't happened often, but..... Her last incident I caught and when I said Lexi she quit midstream and headed for the doggy door, out to the deck, on the grass, and finished her business. Boy, was I a happy camper. The next day she went to the door and all was well. Thought it was licked, but, pee and poop the next day. It just takes a while I guess, or I'm not doing it right!
