Luring, Targets, and Shaping, oh my!

Posted by dfenzi in Lyra, Most Viewed Posts, Musings

When I first started training with food, I used luring.  If I wanted a sit, I held food over the dog’s head and waited for the butt to fall – saying “sit”.  Dog gets a cookie.  If I wanted a front, I took that cookie and centered it in front of my body.  Dog gets a cookie.  For heeling, cookie was held in front of dog’s nose and at my left side.  We then walked when I said “heel” (the dog, cookie, and myself) and at various points….dog gets a cookie.  You get the idea.  That is luring; dog follows the food into desired positions which are simultaneously named.  Over time, the lure is faded and all that is left is a cue – either verbal or visual.  It is no surprise that most dogs are more proficient at the hand signal associated with the lure than with the verbal command, since the focus of their attention was on the hand holding the treat (as opposed to what you might have been saying at the time).

After using the luring method for a while, I discovered two shortcomings.  First, dogs don’t seem to do much thinking when their nose is following a cookie.  I had the vague feeling I was teaching everything twice (once with a cookie present and once without). Second, I learned that luring with a toy is close to impossible, because dogs don’t glue their nose to a tug or a ball and follow it around.  And as a big proponent of toy training, I considered that a pretty big issue.

As I learned more about shaping and clicker training, I became less of a “luring” trainer and more of a “structured shaper”.  (I made up that word…no point in looking it up).

What is a ”structured shaper?”  A trainer who sets up the environment so that the dog is extremely likely to find the behavior that leads to the click very quickly.

Here’s an example of “structured shaping” in heeling:  When your dog is somewhere behind you in a small and boring training area, walk away and call to your puppy while looking at your feet (not back at the dog) and circling to the right.  Wiggle fingers (or clap) on the left side of your body and orient your head slightly to the left. If you picked a sufficiently dull area, your puppy will come up to see you, simply because there is nothing better to do.  As puppy comes up on your left side (they naturally come to where you are orienting), click and feed puppy in perfect heeling position.  If you use a toy, click and reward in that same position.  If your puppy isn’t much for coming when called,  make sure they know you have cookies or toys on you.   I “click” for showing up and I “feed” in perfect heel position.  I turn slightly to the right when I feed in order to teach puppy to drive into heel position rather than just showing up.  If you look back at my first days with Lyra, you can see how I do this on her videos. Within a week, you’ll see that she has a pretty darned good idea about where heel position is, at least on a circle to the right or in a straight line.

I call that “structured shaping” rather than “free shaping” because I set up the situation to make it happen.  “Make it happen” is one of my favorite training phrases.  It simply means to make the choice you want likely without the dog having to think about what it will do.  If you consider what I’ve said for a moment, you’ll realize that there is an element of “luring” in structured shaping.  (My walking away clapping causes the dog to show up in heel position – that is luring with my movement, voice and body position).

If that is my definition of “structured shaping”, then what is “free shaping”?  In my mind, an example of free shaping is “100 things to do with a  box”.  In this game, a box sits on the floor, and the dog is clicked for doing different things with that box, until the dog is offering a wide range of behaviors relating to the box (normally you’ll see nose touches, paw touches, body touches, climbing on or in, barking, etc.).  As a handler, you do not influence the dog’s choices; you simply click and reward the dog for offering a variety of behaviors. Most clicker trainers would say that “structured shaping” is simply a form of free shaping, but I choose to differentiate them because I believe they lead to different end results.  Structured shaping teaches a dog to rely on you and to look for environmental cues about what is desired.  Free shaping teaches a dog to run through a repertoire, only limited by the dog’s imagination.  Eventually, cues are added by the handler to gain control of the free-shaped dog’s behavior.

So where does targeting come in to this discussion?  I see it as halfway between a lure and structured  shaping.  Lyra is taught to follow my finger to get a cookie, which makes my finger the target.  Using my finger, I can “lure” her with my finger…with no food in it….into any position I want.  That is what I found myself doing this morning when I started teaching her some static positions (sit, down and stand).  Eventually I will teach a pop up stand, but for now I simply want her to move between a sit, down and stand without letting her front feet shift position at all.  I decided a finger target was a reasonable way to accomplish this.  I will use targets for other things along the way, but this is my first use of a taget.

Where am I today?  I'm a structured shaper who does very little luring.  I've given serious thought to doing more true free shaping and I have opted away from this option, at least for now.  I'll talk more about why in later posts.

Denise, I have a new Flat-Coated Retriever puppy, Sonic, who I think is about 2 weeks younger than Lyra (8/14 birthday), so I’m really enjoying sharing in your journey with Lyra. I like your term ‘structured shaping’, and in thinking about my approach to teaching, that is really what I’ve been doing for years (vs. free shaping), so I’ll have to steal the term :-) (with credit, of course). It is also great for me to see all the play that you do with Lyra. I’m much more oriented on food as a trainer and I have to make more of an effort to play play play. I love one of your early videos with Lyra where you are doing the very small face/head pushes and you can see her pushing back. Excellent examples of building her drive. Thanks for sharing!

Hello Adele,

My dogs make it easy to use toys, ,because I never get the intensity I want with food. So they motivate ME!
I like your book Competition Obedience; A Balancing Act. Lots of good stuff there!

Great post Denise. I think a lot of people reject shaping because they only think about it in terms of free shaping. I shape everything but it is very task oriented. With high drive dogs through controlling the enviornment they completely teach themselves the skill. I find that this way is faster, more “hard wired” and drive is retained (which results in less distraction). My objection to luring is that it teaches the dog to look towards the handler for cues, even when we fade the conscious ones the unconscious ones often remain – which is a huge problem in my line of work. Through allowing the dog to learn through self discovery we teach them to perform without expecting some key piece of input from the handler first. Something that may be subtle or unconscious on the part of the handler.
P.S. How close are you to Simi Valley? I might be there helping teach a detection trainers course in March or April.

I like, “Makind it happen”.

Hey Lucy; I’m not sure where Simi Valley is, but I think it’s Southern California, so maybe 8 hours away. Not my backyard anyway:).

I’m too impatient to free shape… and also I’m terrible (terrible!) about following through and putting those behaviors on cue, so if I free-shape something I tend to get lots of it, for better or worse. I like “structured shaping,” good description. Now I must think about how I can better myself by intentional use of a target vs. food for a lure. :)

What you say about a lot of free shaping ending up with a dog that throws behaviors makes a lot of sense to me – and I’ve been seeing it happen with my dog lately. Although it does foster creativity…I like your term “structured shaping” and the idea of it, it’s how I normally work with my dog but I’ve never thought much about the form of it or how to describe it. I have one of those weird dogs :) for whom personal attention is more rewarding than food or toys. She responds much better to any form of shaping when I’m offering her encouragement beyond just clicking. I usually use a combination much like you describe, it’s nice to see it explained and justified!

Interesting distinction. I’ve never heard of shaping being broken down like that, although I know that I do offer various forms of assistance when shaping different things. Ultimately, I think the best way to teach a behavior is the one that leads to the dog “getting it” the fastest with the least confusion and frustration. My newest dog has been nearly all free shaped for his various tricks and obedience behaviors. It works because he is creative, but also thoughtful, very attuned to the timing of the click so I can capture things as subtle as weight shifts, and he will “ask” if what he’s doing is right. But if he’s not getting it, I would do something to help him out, whether it be the way I position my body, where I deliver a treat, targeting or what have you.

I’m liking your thoughts…call it what you want as long as you know what it is and can explain it and you did. Makes very good sense.

Thank-you for your insights. I am going to queue this to post on my Twitter, because I think it’s important for trainers to read. I think trainers have become a bit ‘lure phobic’ recently, which is unwarranted. Luring, on any level, is useful, it just has to be used in a methodic and a careful manner to ensure ‘remnants’ don’t become the cue.
