Horse
training and the horse training equipment used for horse training has changed dramatically over the last 20-30 years. Because we
understand what motivates different behaviors in horses so much better than we
once did, much of the brute force of traditional horse training equipment has gone out of training. Thank heavens!
But even
while we strive to be kind and gentle, much of what we do to train our horses
might still be considered “negative.” For example, you pull on the rein—which
the horse would prefer you didn’t do—and when he responds by turning his head,
you let go. Sure, it’s a relief when you release the pressure on his mouth, but
it’s not exactly a “reward”—at least not in the same way that giving him a piece
of carrot would be.
New
evidence from the Equine Research Foundation in Aptos, California, suggests that maybe that carrot
might produce better, faster results and make horses even more eager to learn.
According to Evelyn B. Hanggi, M.S., Ph.D., an equine cognitive behaviorist,
positive reinforcers such as praise, petting and food are powerful tools.
“Horses
learn remarkably well when trained using positive reinforcers,” notes Dr.
Hanggi. “Rewards teach a horse to give you a specific behavior to receive
something good in return.”
For
decades, such methods have been put to good use training many different
species—from dolphins to dogs. Dr. Hanggi and her fellow researchers are hoping
that the same type of rewards will find their way into the training repertoires
of horse owners as well.
The Equine
Research Foundation uses only positive reinforcement in its efforts to discover
how horses learn. This research has been instrumental in debunking some of the
old myths that horses aren’t smart, that they simply react instinctively to
life, and that they don’t really have the ability to learn.
How Horses
Learn
As horse
enthusiasts, we commonly see and use a type of learning called “operant
conditioning.” This type of learning teaches a horse to act in a particular way,
either to get positive reinforcement (something he wants, like a carrot) or to
get rid of negative reinforcement (something unpleasant, like that pesky leg
cue).
The idea is
to strengthen the connection in the horse’s mind between the action and the
reinforcement, so you get the desired response when you use the same cue. For
instance, your horse learns to extend his trot when he hears you clucking and
feels you mildly squeezing his sides with your legs.
Operant
conditioning is a horse training standard. It has been used since humans began
working with horses. In fact, research and practical experience show that horses
excel at this simple form of learning.
“The equine
brain is marvelously evolved to learn different sorts of information in
different ways,” says Andrew McLean, an Australian horse behavior expert and
trainer.
| Building Bridges |
| Give your horse
credit for being the smart, adept learner that he is. Use positive
reinforcement, whether food, praise or petting, to help your horse learn better
and faster. Develop a “bridge,” a
secondary reinforcer, to span the gap between your horse’s correct action and
his reward. At first, reinforce
any effort in the right direction. Then become more selective about the actions
you reward. Condition and
reinforce politeness and respect. Ignore
or discourage any rude or pushy acts. Be
patient and consistent when applying these methods. |
Using
Negative Reinforcement
Perhaps the
most common way we shape equine behavior today is by negative reinforcement. To
mold our horses’ behaviors, we generally use some kind of pressure—the pull on
the rein, the tap of a dressage whip, a squeeze with a leg. This pressure
becomes the “negative stimulus” that our horses want to remove or avoid.
Negative
reinforcement is used before a horse acts in a certain way; it then stops when
the horse does the right thing. Most of us use negative reinforcers every time
we work with our horses.
However,
negative reinforcement should never be confused with punishment. Punishment is
used after the horse has acted in what his rider or trainer would deem to be the
“wrong” way. Equine behavior experts emphasize that punishment is always
confusing and damaging to a horse. It should never be used as a training tool.
While the
idea of using a “negative reinforcer” doesn’t sound all that great either, wise
and caring trainers learn to refine negative reinforcement cues so the slightest
pressure produces the desired behavior.
But what if
you could produce these exact results by offering rewards rather than by
applying, then removing, pressure?
This is what positive reinforcement training is all about.

Understanding Positive
Reinforcement
Positive
reinforcement training may be just the tool we need to give negative
reinforcement a big boost in effectiveness and make both horse and rider feel
good about what they’re accomplishing.
Why does
positive reinforcement work?
“Have you
ever noticed how quickly your horse learns to unlatch a gate, open a feed
container, or dump his water bucket?” asks Dr. Hanggi. “He learns these things
so well because he gets positively reinforced by having a basic need met,” she
explains.
Horses
values things like food, space, companionship, mental stimulation, and physical
comfort. Horses quickly learn that by acting in a certain way, they get a reward
that meets one of their basic desires.
When
someone is first learning to use positive reinforcement techniques, food is
probably the most effective and easiest reward to use. Most horses eagerly look
forward to receiving a piece of carrot or a horse cookie when they respond in
the right way. Scratching or praise can be added later when your horse might be
more responsive to them.
However,
Dr. Hanggi also cautions that this type of training takes knowledge and skill,
so the horse learns good manners along with new behaviors. The last thing you
want to do is to create a rude and bossy “cookie monster.”
The good
news is, horses can be taught to lead, load and lower their heads—even to cross
water—using the reward system. You name it, you can probably teach it using
petting, praise and food as an added incentive.
Constructing a
Bridge
In order to
use positive reinforcement most effectively, a secondary reinforcement, known in
training jargon as a “bridge,” must also be established. The bridge spans the
momentary gap between the time when a horse performs a correct action and when
he receives his treat. It acts as a “right answer” cue.
Bridges can
be whistles, clicks, buzzers, words—almost anything that you want, as long as it
is distinct. It tells the horse immediately that he performed the right behavior
and that his goody is on the way.
How does
the horse understand the bridge?
If we
consistently use the bridge each time we give the reward, the horse quickly
learns to associate the two things, Dr. Hanggi explains.
“Although I
may use a clicker during early training, later I prefer to use the word ‘good’
because I don’t like the restriction of having a clicker in my hand,” she noted.
“And holding a whistle in my mouth, as I did when I was training seals and sea
lions, isn’t the safest practice around horses.”
Movement
Improvement
So how do
we begin to teach our horses using positive reinforcement? Let’s say, for
instance, you want to teach your horse to lift his foot and hold it up while you
clean it.
The first
step, according to Dr. Hanggi, is to look for the slightest movement your horse
makes toward raising his foot and then to reward that movement. Backing him up a
couple of steps will help you get him started in the right direction. When you
signal him and he starts to raise a foot, you’ll give the bridge—your word of
praise—immediately followed by the tidbit.
At this
point, all the horse really understands is that when he does something, he gets
a reward. Eagerly, he will start to try all sorts of behaviors looking for his
goodie. But if you only reinforce the one movement you want—raising a foot—he
will soon concentrate on this one behavior.
At first,
you might get a foot lift that barely clears the ground, or is just a quick
up-and-down movement. To encourage your horse to change this to a nicely raised
foot, you will reinforce primarily those lifts that come closest to your goal,
in other words, the ones that are of a desired height or duration.
When you
hold off on the bridge, your horse will try many different behaviors looking for
the reinforcer. One of these behaviors will be a better, higher, longer lift.
Reinforcing that specific behavior immediately sends the message to your very
smart horse that this is what you want.

Dr. Evelyn Hanggi demonstrates how this horse has learned that a hand signal and the word “foot” are a request to lift his foot and hold it.

“You want
to be careful not to inadvertently reinforce other concurrent behaviors, such as
tail swishing or ear-pinning,” notes Dr. Hanggi.
Remember,
too, that this learning process will take quite a few trials, not just one or
two.
“When I
train new behaviors,” Dr. Hanngi explains, “I usually get a pretty decent result
within about 10 minutes. I then improve on it, shape it, during short sessions
for a few days.”
You might
also need to relax your parameters for a moment and backtrack if the horse
becomes confused.
The final
step is to connect the behavior to a cue, such as a hand gesture or a word. In
this situation, perhaps you’d use the word “foot.” Right before your horse lifts his foot,
you say the cue word. This has to be done consistently. After you get good at
this, you can almost sense what the horse will do next.
“Remember,
though,” cautions Dr. Hanggi, “that it takes time and skill to get good at
this.”
Until then,
you can give the cue at the earliest moment of the lift. If you only reinforce
him when he lifts his foot in response to that cue word, he will quickly make
the connection that “foot” means to pick up his foot high and hold it there.
So, do you
now become the walking grain bag or carrot keeper to get your horse to do what
you want? Dr. Hanggi says no.
“Once the
horse understands your cues, you can put him on a variable reinforcement
schedule,” she says. That’s a fancy way of saying, instead of giving the horse a
reward each and every time he responds correctly, you’ll reinforce the right
behavior intermittently.
Dr. Hanggi
has found that horses will work harder and respond more enthusiastically when
rewards are not given on a predictable basis. Once a behavior is learned, food
is faded out and only given occasionally, such as at the end of a training
session, or even not at all. Eventually, the secondary reinforcer (that word of
praise, for example) is reinforcement enough.
Clicker
Training & More
Of course,
there is still a mindset in the horse world that questions using food to
reinforce desired behavior. If you train by reinforcing with food, do you then
run the risk of having 1,000 pounds of pushy, irritating horse who is always
looking for food and disrespecting your space?
Not only
would this be annoying, it could be dangerous.
“When food
reinforcement is involved, it is extremely important to know when to reinforce,
when not to, and how to gradually fade out food so you’re not encumbered by it,”
Dr. Hanggi says. “Do not confuse positive reinforcement training with
treat-giving.”
The key is
to reinforce only appropriate and correct behaviors, and to time the
reinforcement precisely so that it’s most effective. Be careful not to reinforce
undesirable behavior, such as biting or licking at your pockets or encroaching
on your space. Conditioning horses to be polite is paramount. In fact, this is
the first thing Dr. Hanggi and her associates teach participants who attend
their positive reinforcement clinics.
For years,
the dog world has been using positive reinforcement as a training tool. In fact,
a whole discipline called “clicker training” has evolved, an adaptation of what
has long been used with dolphins and whales. The metallic clicking sound made by
a small, hand-held device is used as the bridge. The dog recognizes the click as
a “good boy, that’s right” signal. Clicker training is also being used with
horses, eliciting rave reviews from those involved.
Ultimately,
we all want to be nice to our horses. By being able to thank them for performing
in a way that we want, we both win. And as we progress with our positive
reinforcement program, we will begin to see the value of working in a truly
rewarding way with our perfect horses.
