The tendency with trailer
loading, like everything else people do with horses, is to
try
and bribe the horse with a treat. As in all aspects of gentle natural
horsemanship training, trying to coax a horse to do something using a
carrot or a bucket of grain is a no-no. A horse should not be
bribed into doing anything for you because that does not teach the
horse to respect and trust you. We want our horses to view us as
trustworthy leaders that they respect. When we accomplish this, the
horse will enter a trailer because we ask her to do so, instead of
doing it because there is a carrot at the other end. This builds
confidence and respect, and like catching and leading the horse,
properly trailer loading the horse will lead to success in all aspects
of your relationship including riding.
Approach and Retreat
The
single key concept you need to etch in your mind for trailer loading is
Approach and Retreat. With trailer loading, this is simple to execute
but requires patience to do it properly. When describing how to do it,
we are going to assume that you have a horse that is reluctant or
scared to enter a trailer.
Step 1: Initial Approach
The
first step is to bring the horse up to the trailer without asking
anything of her. Have your horse on a lead rope and halter, and bring
her out and do some initial ground work for a few minutes.
Then
approach the trailer. Just walk right up to it and stand next
to
it. On the first approach, do not ask her to enter the
trailer.
Wait there a minute or two and let her look it over and smell it.
Your
goal here is to begin to teach her the trailer is not a place of
fear. Like anything else in horse training, we want
to
remove the uncomfortable stimulus, which is being present by the
trailer in this case, before she comes unglued. Your horse may not do
so before getting in the trailer, but you need to apply this procedure
anyway. If the horse does come unglued just being by the trailer, time
how long it takes before this happens. Then remove the horse from the
situation and bring her back to the trailer.
If the horse
comes unglued in say 5 seconds, bring the horse up to the trailer and
let him sniff it and look it over. Count in your mind to 4 seconds-one
one thousand, two one thousand, three one thousand, four one thousand.
Then walk the horse off in the opposite direction from the trailer,
removing the stimulus.
Before
asking the horse to enter the trailer the first time, do
some
groundwork
exercises to establish leadership.
The
first phase of approach is to walk the horse up to the trailer. Let her
smell it and look around, and then walk off and move her away from the
trailer.
Step Two: Approach and Retreat Backing
out of the Trailer
The
next phase of trailer loading involves gradually increasing the
stimulus. So next we walk the horse up to the trailer and ask her to go
in. Make sure you ask for small gains and don't get greedy about what
you are asking. The idea here is to lay a solid foundation one brick at
a time. So we might begin with a real timid horse by just asking her to
put her head inside the trailer. If your horse is difficult to trailer
load but not that timid, you might ask her to put her front foot up in
the trailer.
Regardless of how far you take that first
step, don't ask for anything more. A horse that is reluctant to trailer
load is thinking BACKWARDS when we are asking him to get in the
trailer. This is where we can apply the steal a thought idea from
catching.
Let's say that the horse we are working with puts his
front foot in the trailer. He might seem OK at that point, and you
might have the tendency to keep asking. This is where being GREEDY gets
you into trouble. If you ask the horse for more at this point he is
going to start getting uncomfortable and be reluctant to enter the
trailer.
Instead, when the horse puts one foot up in the
trailer, then reward him with petting, verbal praise and use deep
breathing to promote relaxation. Then ask him to back out of the
trailer. This has several advantages:
It lets the horse gradually build confidence without coming unglued,
which would put us back to square one in loading.
It
helps the horse trust you, since you're slowly showing him
that
the trailer is not a place to fear, without asking him to be confined
in it right away.
Horses learn in slow motion-so ask them for small steps-one at a time.

Here
the horse has put both front feet in the trailer, but she is nervous.
We stop and pet the horse and praise her verbally for giving us what we
want. Exhale loudly to promote relaxation and a decrease in energy.
Now,
ask the horse to back out of the trailer instead of trying to
get
more out of her in one go. This promotes gradual learning which is more
effective.
Step Three: Increase the
Pressure
When
you are making progress at each step, its time to turn up the pressure,
but in small steps. Maybe the first time you get him to put both front
feet in the trailer, you keep him in the trailer for say 5 seconds.
Repeat the process two or three times increasing the length of time he
is in the trailer to say 7 seconds, 10 seconds, then 12 seconds. Each
time, while the horse has part of her body inside the trailer, pet
liberally and provide a lot of verbal praise. You want to get inside
the mind of the horse and teach her that the trailer is not a place to
be feared, but is instead a place of comfort. Remember that for a prey
animal like a horse, a dark confined space is going to be viewed as a
place of fear, a place where they might be killed or eaten. This is
instinct. We are asking a lot of them by having them overcome this
instinct and get in the trailer.
But doing it gradually we are
teaching the horse that the trailer is a source of comfort. At each
stage, when you get a horse to make reach a major milestone, say going
from just putting one front foot in the trailer to putting both front
feet, when you back the horse out move him far from the trailer and
walk him around to give him a mental health break. Do a small amount of
groundwork before asking him to enter the trailer again.
Continue
the gradual increase in pressure. Once both front feet are in, ask the
horse to put one back foot in the trailer. Use the same process we have
discussed so far. Instead of asking for more at that point, back the
horse out of the trailer instead. Then repeat, keeping her in the
trailer just a second or two longer. Eventually, the horse will put her
entire body inside the trailer and be relaxed. How long it actually
takes depends on your individual horse, but have patience. If you stick
it out and get the horse to enter the trailer without using any treats
or carrots and do it in small steps, you will have a solid horse that
will be anxious to get in the trailer, instead of one that has to be
coaxed in.

Repeat the process going further each time. Here, Eric has both front
feet in , and is asking the horse to put her back feet in.

Now
she is all the way in. Not a single treat was used and she is
comfortable and relaxed in the trailer. The entire process took about
30 minutes. It may take you longer, but stay focused and patient for
long term success. You might consider breaking the steps described here
into sessions over several days.
