Clicker Training for Dogs: How It Works, and How to Use a Marker Word Instead

Dogs learn from what happens in the second after they do something. By the time you’ve dug a treat out of your pocket, your dog has usually moved on to something else, and that’s what gets rewarded. A marker closes the gap. It’s a short sound that means “that, right there, earns a treat.” That sound can be a clicker or a word. A clicker is a small plastic box that makes the same sharp click every time; a word has the advantage that you always have it with you. The steps below use the word “Yes!” To use a clicker, click wherever the steps say “Yes!” and change nothing else. The goal: In five minutes, your dog learns that “Yes!” means a treat is coming, and you’ll see their head snap round when you say it. Time: about 5 minutes. You need: 20 pea-sized soft treats, a quiet room.

Use the marker in everything you teach from here on: the instant a bottom hits the floor, the instant the leash goes slack, the instant your dog looks at you instead of the squirrel. Mark first, then reach for the treat. Keep the promise. Every “Yes!” is followed by something your dog likes, even if you marked by mistake.
