I've been using Shirley Chong's shaped retrieve with Mal and the dumbbell and it's been kinda slow- mostly because my timing isn't very good. (Sometimes I think that my brain and hand communicate via a cell phone with REALLY bad reception. Sometimes I even think "wait, don't click, he did it wrong that time!" and my hand clicks anyway. ARGH. And a verbal marker really isn't precise enough with Mal, he really needs me to be exact about what I'm rewarding.) Any rate, we'd gotten off on this tangent in which he believed the goal of the dumbbell was to grab it by the end and fling it at my head. This was obviously NOT a desirable state of affairs and I've been meaning to do something about it since he nearly brained Springingpups (who is my training partner) with it last week. Good training partners are hard to find. :P
So, today, we took a BIG step back and went back to the beginning. Some stuff went faster this time- he started over with the nosepokes right away (I cheated and held it down with my foot for the first five reps) and then started the nose-flipping that'd lead into our original problem. I tried waiting for him to get a tooth hit on it and it wasn't happening (probably because of the structure of his head- he's got a very nice level bite but the end of his muzzle is shaped like this

------/
And I think that doesn't help matters- a nose bump is really easy, but a tooth hit is hard unless the item is at a particular angle. So I cheated. He's used to me having hands in and around his mouth and I'd been reading about using a finger-hold in "Competition Obedience- A Balancing Act" as a way to teach your dog to close his mouth and not chew on the dumbbell. The author of that talks about using a CR (Conditioned reinforcer, ie a clicker or verbal marker) with shaping a dumbbell hold so I opened his mouth, put the dumbbell in, clicked, and jackpotted- he dropped it to grab the treat, but it took three reps of that before he figured out what I wanted him to do with the dumbbell! Go Mal! He's now putting his mouth on it reliably- the pickup and hold will come in time. I'm just glad that first little lightbulb has gone on.
I love freeshaping and I always forget how powerful it is- I don't find it as useful for behaviors that are easy to teach in other ways (ie sit, heel, LLW, down, stays), probably because they're much more natural than a formal retrieve- so I don't tend to use it nearly a often as I should. I mostly use it to polish existing behaviors. With my next dog, I'm going to do a MUCH better job of keeping a training journal- and I'm going to try and freeshape EVERYTHING I can. :)
