Marker Word

What it means

A marker word functions as a bridge without needing to carry a physical clicker, though it's typically slightly less precise since a spoken word's timing and tone can vary more than a clicker's consistent sound. Whichever is used, it has to be taught first (paired with a reward repeatedly) before it carries any meaning to the dog.

A real example

A trainer says "yes!" the instant a dog's paw touches a target, then delivers a treat a second later, the same mechanism as a clicker.

A worked example

Lucy teaches the word "yes" in the kitchen: say it, give a treat, 15 times. Later, in the garden, her dog looks at her and she says "yes" and throws a treat. The dog soon repeats looking at her, because the word marked it exactly.

Signs it is working

• The dog looks for the treat right after the word.
• It repeats the behavior you marked.
• It does not react to the word in normal conversation as a cue to do anything.

What it is not

A marker word is not a release word. "Yes" says a reward is coming, while a release such as "okay" says the dog may move.

Why it matters

A marker word means you always have a bridge with you, even when your hands are full. It is the practical choice for everyday training.

How to use it

1. Choose a short, distinct word you do not otherwise say much, like "yes".
2. Say it in a crisp tone, then give a treat. Repeat 10 to 15 times.
3. Mark real behaviors the instant they happen, then reward.
4. Always follow the word with a reward, even if you marked by accident.

Can I use the same word as praise?

It is better not to. Casual "good boy" is vague and constant. A dedicated marker keeps its sharp meaning of "that exact thing, reward coming".
