When Draco was a puppy, I started teaching him to ring a bell when he needed to go outside. I soon figured out that there was no need to, as he had devised his own way of telling me that it's potty time. he gives me a few low grunts to get my attention, then when I ask if he needs to go, he turns around, almost as if he's saying "yes." It really is crazy -- sometimes he won't respond, but will turn around if I ask if he's hungry -- almost like a form of sign language. I know some people will think it's boring, but I just wanted to demonstrate how smart Dobermans really are! As you can see, he ended up training ME. :) (less info)
