I just bought a clicker and the book "Click & Easy" at Petco. Taz is starting to respond to it well. The book is very informative and it teaches basic obedience as well as tricks. I will keep everyone posted on his progress. He is 10 months old by the way and only had a few basic commands down when I got him 2 wks ago. (Sit occasionally and let's go Bye Bye down pat).
