Feeling Pawsitive Veterinary... A marker is a short, consistent sound β a clicker, or just the word "Yes" β that means exactly one thing: a treat/reinforcement is coming, and it's for what you just did.
Here's why it matters. Between the behavior you liked and the moment the treat reaches your dog's mouth, they do about six other things. The marker freezes the right behavior.
How to start:
Say "Yes," then hand over a treat. Don't ask for anything first. Repeat ten or fifteen times across a couple of short sessions, until your dog's head snaps toward you on the word "Yes".
Now it's a tool. Use it the instant your dog does something you'd like to see more of.
Timing is most important every time.
