What Are Marker Words and Why Do They Change Everything?

If you've ever watched a skilled trainer work and thought how does the dog know exactly what they want? Marker words are usually a big part of the answer.

Put simply, marker words are specific words you use to communicate with your dog in real time during training. Not commands but feedback. They tell your dog "yes, that's it," or "keep going," or "nope, try again." Done consistently, they cut through the confusion and make training click so much faster.

Here's how they work in practice.

"Yes" — The Terminal Marker

This is your money word. The moment your dog does what you asked, you say "Yes" and that word means two things at once: you got it right, and the reward is coming. It also releases your dog from the behaviour; they don't need to hold it anymore. One sharp, clear word does all of that.

The key is timing. "Yes" needs to land at the exact moment of the correct behavior… not a second later when your dog has already moved on to sniffing the floor.

"Good" — The Duration Marker

"Good" is your way of saying yes, but keep going. It's used when you need your dog to hold something. Think when you give your dog a stay, a heel position, a calm place on their bed. Unlike "Yes," it doesn't end the behavior; it encourages your dog to maintain it while letting them know they're on the right track.

Think of it as a running commentary: good... good... good... until you're ready to release them with a "Yes" and a reward.

"No" — The No Reward Marker

This one often surprises people. "No" in marker training isn't a telling off — it's just information. It calmly tells your dog that the choice they made isn't going to earn a reward, and gives them the chance to try something different. No drama, no frustration. Just that's not it, have another go.

Used this way, it keeps training clear and keeps your dog thinking rather than shutting down.

So Why Does This Matter?

Dogs don't know which part of what they just did earned the treat. Without a marker, you're leaving them to guess. With one, you're pointing at the exact moment and saying that — do that. It's clearer, it's faster, and it builds a dog who's genuinely engaged because they actually understand exactly what we want.
