My Dog used a Litter Box until 12 Weeks of Age. After that, I took her to the Horse Farm and let her 'Pack' with older well-trained Dogs. She mimicked their behaviors and she learned how to Sit, Stay, Come when called and lay down. The Dogs did a great job of training mine. I did not have very many problems. these dogs get a bad reputation for being hard to train but they really aren't. They are very stubborn and would rather die than negotiate. Therein lies the importance of understanding the Dog's body language, that tells you all you need to know. They are extremely intelligent and never forget a thing, including people and other animals. Good luck with it!
