The "stay" cue is a super useful skill that every dog should know. It's a foundational skill that can be paired with many other cues in a variety of situations. You can use the cue "stay" on walks to prevent your dog from dashing across the street or when opening the door to grab the mail, and you can even add it to a more complex behavior like "go-to-bed."
Why Training Dogs with Treats Is an Effective Way to Teach New Skills 
Carson Downing Form an Effective Marker
A marker (also called a bridge or bridging stimulus) is a sound or hand signal that tells your dog the exact moment they did something that earned them a reinforcer (the treat). A clicker is a great tool to use for this. If you don't have a clicker you can just use a word like "yes" or "good" or a hand signal like a thumbs up, but pick one and stick to it. Mark the behavior the second you see it. The more accurate and quick your mark is, the more effective your teaching becomes.
5 Steps to Teach Your Dog to "Stay" on Cue
01 of 05 1. Reinforce for Remaining in Front of You
Carson Downing With your dog in front of you, begin reinforcing him for remaining in front of you by giving him treats. He can be standing, sitting, or laying down—as long as he doesn't walk away, he gets treats. You quickly will discover which position he prefers.
02 of 05 2. Ask Your Dog to Sit, and Add a Cue
Carson Downing Now that you have his attention, ask your dog to "sit." The moment he does, mark the behavior and give a treat. Repeat this several times without saying anything or moving so that your dog understands that remaining in that position equals treats. Then, still without moving your body, present an open hand facing upwards towards him (hand signal) OR say the word "stay" (verbal cue). Pick one and stick to it because this is your cue. If he stays in position, mark the behavior and give him a treat. Repeat several times.
03 of 05 3. Take a Step Backward
Carson Downing With your dog still in a sit position give your hand signal or verbal cue. Slowly rock back on one foot or take one step back and immediately return to him. If he remains in position, mark and reinforce.
04 of 05 4. Add More Distance
Carson Downing Don't rush this or move too far too fast! You may find you can only take a one or two steps away at first to make sure your dog is successful. Raise your open hand or say your verbal cue "stay," and take a step or two backward then immediately return to your dog. If he stays, mark the behavior and give him a treat. Repeat this several times.
05 of 05 5. Work On the 3 "D's"
Carson Downing Continue to strengthen the cue by gradually working on the three "D's": distance (how far you step away), duration (how long your dog remains in position), and distraction (noise, things that move, sounds, etc). Focus on one "d" (like distance) before you move to the next.
Tip: Always set your dog up for success by going slow and reinforcing constantly. Think baby steps! If at any point your dog doesn't hold the stay, consider if you are moving too fast or if your rate of reinforcement is too low. Go back a few steps in the process and reinforce him for shorter periods of time (and smaller distances away from you) in the position.
Using positive reinforcement makes learning new skills for your dog fun and easy. With more experience, and practice, you can teach your dog shake, roll over, heel, fetch, and tons of other new dog tricks they need to live happily by your side.
