I've been training dogs for 30-something years, and it's the most effective form of communication I've found. You can teach things with a clicker (or other marker) that would be almost impossible with traditional techniques. I think the hardest thing is teaching yourself to be observant and time the click correctly. Put your dog up in another area where he won't hear you, and practice clicking the newscaster on the evening news when he blinks his eyes. If you can do this, you are probably ready to start working with your dog. I would read up on it a bit first, if you're not going to classes so you understand how it works. Karen Pryor's "Clicker Training, Getting Started" is a good place to start. Have fun!Is it hard to train with a clicker and how affective is it
