What Sit Really Buys You

You now have the mechanics. Here is why they matter: every rep is teaching three things at once, not one.

• The marker — "yes" tells your dog the exact instant they got it right, like a camera shutter freezing the moment.
• Attention — to earn the treat, your dog has to watch you. That focus is the raw material for everything else.
• The contract — do the thing, get paid. Once a dog trusts that deal, training stops being a fight and becomes a conversation.
