How Do You........

That's alright. You can recondition the clicker and choose another noise to distract Dasher, such as a can of pennies or simply "AH AH!".

I haven't shaped a "Hold It" with Ivy yet but I figure it would work similar to this:
1) C/t (click and treat), c/t, c/t. Stop.
2) Hold out a bone or stick. Every time dog even nudges the bone/stick, click treat. Repeat repeat repeat. Stop.
3) Dog thinks, dog will probably start to mouth the bone/stick. Click treat, repeat repeat repeat. Stop.
4) Dog thinks some more, dog will probably grab the bone/stick from you. Click treat, repeat repeat repeat. Gradually let the dog hold the bone for longer periods of time, all the while marking his good behavior with c/t. Eventually, you can add the cue word.

Again, I haven't personally tried this, but my experience tells me that this is how you should progress. I think I'll try it out tomorrow, in fact

In order to "Cliker Train" you don't need to use a clicker. I free shaped with my two older dogs to teach them to retrieve a stick from the ground and hand it to me (a Lab and a Lab mix that don't play fetch...weird, I know) and I never once used a little plastic box with a metal slab in the middle.

The marker word I use is "Yes!". At the moment when someone using a clicker would be clicking, I say, "yes!" It's simple, not a word I use much in day to day conversation, short, it leaves my hands free, and I always have it with me.

I agree with the training methods listed above. "Hold it" sounds like a good command to use.

Clickers are simply markers. You mark the right behavior, you stop, the dog thinks and performs. In essence, the dog is teaching himself. You're just there to guide the dog. "Yes!" works, but not nearly as efficiently as clickers. Voice pitches vary and, speaking from personal experience, my body thinks faster than my voice

The clicker is a marker of good behavior - nothing more. Sounds too simple if you ask me, but that's all there really is to it! If you can find a better marker, use it

This is exactly how I taught Dance her "hold" and she caught on in about an hour all together, except I skipped the nudging part as she just wanted to grab or mouth it right away. It took about two days all together, maybe a little less, before she knew what "hold" meant. It's really simple and easy.

I didn't read what everyone else said, but to me dogs jst kinda hold things in their mouths when they want to. That's how all mine are; they like to play w/ their toys and all but only 'when that feel like it.'

I'm just being curious...what kind of dog is Dasher? A friend of mine had a JRT named Dasher, but he died a few months ago
