This fun training technique can be used to teach your dog anything.
By Pat Miller Yard sales and flea markets are some of my favorite places to shop for dog training equipment. A couple of years ago I picked up a classic Wizard of Oz picnic basket with a lid that flips open the kind Toto jumped out of while being dognapped on the Wicked Witchs bicycle. That basket sat in a corner of my training center for quite some time while I pondered what to do with it.
Shaping, or as its formally known, shaping by successive approximations, simply means breaking down a behavior into tiny increments, and reinforcing the dog at each incremental step until youve achieved the full behavior. Some trainers believe that shaping is the ultimate approach to operant training, and that any steps that stray off the pure shaping path are detrimental to ultimate results. Others incorporate shaping as I do as valuable part of a multi-faceted training program.
The science behind it
Perhaps you choose to start with speed. Your dogs average sit time might be three seconds. Your goal is a one-second sit. In any given number of repetitions of Sit, some will be faster than three seconds, some will be slower, and some will be right on the three-second mark.
If you were to be scientific about your shaping program, youd time the sits with a stopwatch, only click and treat (mark and reward) those that were three seconds or faster, and keep a written journal of your progress.
If you are less rigorous, youd guesstimate the times and strive to click the faster sits. Over time, your dogs average elapsed sit speed time would decrease, perhaps to two seconds, as he realized that only faster sits get clicked, and deliberately tried to sit faster to make you click more often.
Now you raise the bar only sits that are two seconds or faster get clicked. By breaking your goal of fast sits into smaller increments of time, you gradually shape your dog to do that lightning-fast one-second show-ring sit that you covet.
Shaping is not just for the show ring. It has a number of important applications and benefits for all kinds of training, including:
Accomplishing a behavior that your dog finds physically difficult or confusing, such as a teaching a Greyhound to sit.
Encouraging your dog to perform a behavior that he finds mentally difficult or confusing, such as teaching a crate-wary dog to enter his artificial doggie den.
Fine-tuning a behavior your dog can already do, such as teaching fast, straight, close sits.
Helping your dog learn how to offer behaviors, try new things, and think creatively in order to solve problems, through shaping games such as 101 Things to Do With a Box. Shaping techniques
Shaping purists tend to scoff at lure/prompt shaping, but it can be very effective at getting behaviors more quickly, although slower at teaching dogs to think creatively and offer behaviors freely. Dogs in basic good manners classes are often taught the Down with lure-shaping, by luring the dogs nose toward the floor with a treat, clicking and rewarding as the dog makes any progress toward the floor with his nose or other body parts.
You can use basic shaping, where you have a goal behavior in mind and, without any prompting, reinforce small increments that the dog offers, such as described above for a faster sit. And you can free shape by doing training exercises without any preconceived notion of where you want the behavior to go. Free shaping is the most difficult concept for novice trainers, who are often legitimately perplexed by the idea of training without knowing what behavior youre trying to train.
Lure/prompt shaping
To lure-shape a sit in a reluctant sitter, hold a treat at the tip of your dogs nose and lift it up slightly. If he lifts his nose to follow the tidbit, click and treat. Repeat this step, lifting the treat slightly higher and a little bit back over the head.
When each step seems easy for the dog, progress a little farther, continuing to move the treat back over the head. At the same time, watch for a bend in the hind legs. Be sure to click the slightest bend in the hocks, and when you start getting a consistent bend in the hocks, even a small one, keep luring, but only click the leg bend, not the head lifts. Reinforce gradually deeper bends in the legs until the dog is sitting.
Other dogs resent being physically manipulated. That may or may not be the reason I had a recent client whose Scottish Terrier caused serious injuries to his prior trainer when she tried to push him into a sit. He resisted her first two push-sit attempts, and on the third try went up her arm with his teeth.
But other dogs may have other reasons for failing to catch on quickly. A case in point is a shelter dog I saw in my Intern Academy last summer a beautiful English Pointer who had been purchased for hunting trial work but disqualified from competition due to a minor congenital rib deformity. At age four, he had never been asked to sit, and just didnt seem to understand what we were asking of him.
In fact, he was the classic example of a shut-down dog unwilling to offer any behavior at all. It took four days of the six-day academy, but on Thursday when his trainer finally got him to sit, the whole class applauded wildly. Best of all, the dog got it! His eyes lit up, and he proudly offered sit after sit after sit. In the remaining two days of the course he and his trainer caught up on all the lessons that had been on hold while they worked on the sit, and both graduated with flying colors and big smiles.
Basic shaping
To shape a Go to Your Place behavior, set out a carpet square, dog bed, or blanket to designate Place. You can actually do this without a physical object to mark the place, but its easier for canines and humans to succeed with a visual marker and then you can generalize the behavior easily by moving the marker to another spot.
Now stand back several feet from the carpet square and watch your dog very closely. Youre going to click and treat the tiniest motion toward Place one step, a turn of the head, a flick of the ear ... it doesnt even have to be directly toward the spot in the general direction will do.
If youve already reinforced your dog consistently for offered behaviors, hell probably catch on quickly. As he starts repeatedly making deliberate movements toward the rug to get clicked, youll hold out slightly longer to build more behavior. Just slightly! You want him to get a little frustrated and try harder (harder = bigger behavior), but if you hold out too long he may give up and quit offering behavior altogether.
As he gets closer to the mat you can move forward with him in order to keep delivering treats but not ahead of him that would be luring or prompting!
When hes reached the mat, reset. Move yourself and your dog several feet back and start again. The goal is to shape him to go to the mat, not just to be on the mat. When he offers to go to the mat easily, start shaping him to lie down on it. The value of this exercise is to be able to park your dog there for a while. When hes consistently offering to go lie down on his mat, you can add the verbal Go to Your Place! cue.
If your dog doesnt offer behaviors easily, it may take longer to shape the Place behavior. Be patient, and remember to split look for the tiniest of movement to reinforce. If he wants only to gaze adoringly into your eyes, look at the rug instead of him. If he just lies down at your feet for a snooze, invite him back to his feet, reposition him, and look for movement to reinforce as he repositions. The more you can find to reinforce, the less likely he is to lie down for another nap.
Dedicated shapers may write out their complete shaping plan, considering each potential step in the process, and measuring their progress against the written plan. Less scientifically disciplined trainers may work with just a mental picture of their shaping plan. You can do each shaping session for as long or as short as you like. Assuming your dog is happy to play the game, you can keep on playing! As with all training, try to end the session while your dog is still enthusiastic and successful.
Free shaping
101 Things to Do With a Box You can use any old cardboard box for this, or it doesnt even have to be a box! You can play 101 Things to Do With Anything.
Your dog can be on leash, or off, if hell stay and keep working with you. Set a chair a few feet back from the box or object, sit in the chair, and wait. As with the Place exercise, youre looking for tiny pieces of behavior to click and treat any behavior that relates to the box a look, a step, a sniff, a push ... only this time you have no specific goal in mind, and you dont have to build up to a behavior random behaviors are fine.
If your dog gets hung up on one particular behavior you can stop clicking that one and wait for something else. The more confident your dog is about offering behaviors, the more easily you can just quit clicking one thing and wait for another. At some point, if you wish, you can decide on a goal behavior based on the ones your dog has offered, and shape it into something specific front feet only in the box; hind feet only in the box; all four feet in the box; turn the box over; fetch the box; or...?
Body Parts Body Parts shaping helps your dog learn to offer behavior, and it also helps you realize how precise this process can be for shaping the tiniest of movements.
When you have captured one of these movements with your click and treat, thats the one youll continue to focus on. Sit and wait for another movement of that same body part. Click and treat. Your goal is to reinforce that accidental behavior until your dog begins deliberately offering it. When he does, you can name it, incorporate it into a trick routine, or keep working with it to shape it into something bigger if you choose.
I really came to appreciate the power of shaping when I first purchased agility equipment, set it up in the backyard, and ran to get Dubhy, to see what hed do with it. To my delight, as I introduced him to each piece of equipment, he immediately started doing stuff sniffing it, pawing at it, biting it, jumping on it, just trying out different things to see what he needed to do to get me to click. Made training a breeze!
