This is the clamshell game. This game is used to increase your dog's impulse control around food and distractions. It's also a fun game to see how quickly your dog can learn a default leave-it behavior, and to defer to you when they want something, by giving you eye contact to "ask for it", or backing away from the item they want. 

The way this game works is that your hand is what is training the dog. What we're going to do is put 3-5 treats in your hand and present your closed fist to your dog. She will try to nibble, lick, chew at your hand. As soon as she backs off your hand, the hand opens to reveal the cookies. If she dives back in for them (which she likely will) the hand closes. When she backs off, even for half a second, the hand opens. If she can back off for one second, you mark that with a "yes" and use your other hand to take the cookie from the hand that is "in play" and reward. 

The goal is to have the hand open all the time with a pile of food in front of her. However, in the beginning it will look like a hand that is opening and closing a lot! This is a game for the human coordination too! So remember, hand is only closed when she tries to get the food, otherwise the default position is open. And it's important that your hand never moves away. The hand stays planted in one position, and simply opens and closes. Glue your elbow to your side to remind yourself of that if you need to, as everyone's initial reaction is to pull the hand away rather that simply just close your hand over the treat. 

Once you master this game in the hand, you can also play it with food on the counters to teach a dog not to steal food from the counters (treat from your pouch, not the counter), on the floor, on a coffee table, all over the place, to increase the level of difficulty. 

Happy Training!

Hi Laura! I am currently working on this with my 7 month old Chihuahua mix puppy. My question is, since he has learned the hand target, it occurred to me that this might be confusing for him since I am giving him a very similar signal to do the opposite action. How can I teach this without confusing him?

You could teach your hard target with either a flat palm or two fingers out as an alternative if you think he's getting/will get confused. Most dogs understand context and the way you present the hand, but modifying your hand target configuration will definitely solve the problem!

Laura, my dog is EXCELLENT at the clamshell game, can leave dropped food items during training in the house and even outside, etc., but when we’re not explicitly training this, or if the item on the floor is very valuable to him (i.e. leftover food containers on the sidewalk or things I don’t see but he does (i.e. little crumbs underneath a coffee shop table), he goes for it. He tries to go for the dead animal on the side of the road, etc. and since his nose is 59284838x better than my eyes, he detects the presence of the valuable item way before I see it, so there’s practically no time for a “leave it”. How can my dehydrated chicken breast treats “compete” with the smell of rotten roadkill??? We’re struggling with this, SOS!!

So it sounds like you need to work more on generalizing the behavior. That means I am purposefully going to seek out distractions in the environment to work around. Your dog might think this skill only applies to certain scenarios. You need to do setups out in the world. Example, how often have you practiced with leftover food containers on the sidewalk? as in, you bring a leftover food container and practice out in public? When you see roadkill, can you use it as a training opportunity? We want our dogs to think that training happens everywhere, and in the case of dogs that are super into things on the ground, it means creating those scenarios to practice around. (which is, yes, a lot of work).

This is always so helpful to see again! Watching you teach it this time I realized I always had asked for a sit or a down first, and it makes perfect sense that a dog wouldn't generalize that behavior to times he hasn't been given a cue

DOGGY•U

Absolutely! I can start with a down or sit cue to help if the dog is struggling, but I do want to phase it out. This is also one that has to be taught in SO. MANY. LOCATIONS for it to generalize. But it's a fun one and the reason I can leave my entire meal on the coffee table every night to go back to the kitchen to get something without worrying the dogs will snag it while I'm gone lol!

Looks like I have something new to teach Hank!

What a good "demo" dog for this exercise. You can see all the wheels turning for him. :) I had only learned a cued "leave it" before learning IYC from Susan Garrett. I'm currently reading Hannah Branigan's "Awesome Obedience" book and that's the first I'd heard it called the "Clam Shell" game. This idea of a default "leave it" has been really powerful for my dogs and I. Such a great game, always love to see it again with a different dog.

DOGGY•U

Yes! I love this game - I think I mentioned it above but this (and beyond the backyard teaches similar stuff) is what allows me to leave my plate of food on the coffee table while I go to the kitchen to get more things. I never have to worry that my dogs will steal my food :)
