Here's how to do it:
You can either use a clicker or a marker word to mark when the dog does the correct behavior. Have an idea in your head of what you want your dog to do. If you're wanting your dog to raise its paw in the air, wait for him to move one of his paws and then click and treat. Be very patient with this as the beginning can be a little slow. As your dog starts to catch on he will start raising his paw more enthusiastically. This is just one example. The overall idea though is to have a goal in mind and to get your dog to do pieces of the goal. Once you have the pieces you can put them together into a sequence.
Here are some other important bullet points:
-Stay patient. This is a slow process in the beginning.
-Limit the amount of communication you do towards your dog while doing this. In most cases it will just lead to confusion.
-Use small treats that your dog will want to work for.
-If your dog starts getting frustrated, ask for an easy behavior and reward that. If a dog gets too frustrated it will give up thus ending the game.
-Every dog is different, but overall try to keep sessions to around 10 minutes.
-Kibble can be used for this game for some dogs.
-Start this off in a relatively distraction free environment. (You want to be the biggest "distraction.")
