Thanks. We'll give that a try. He already expects a treat when he sits so we have a "head start"
Some friends of my parents down in coastal GA own (or are owned by) a little hellion of a Jack Russell terrier. Their previous dog had been a very laid back Lab, and this little dog was completely wild and out of control. I mentioned clicker training when we were over to their house for dinner -- they were very interested (not to say desperate) and I brought my dog over to demonstrate the method, then we started on their dog. It was amazing! Within an hour we had her doing several basic commands, and I hear from my folks that she is continuing to progress and is a much better behaved dog!
