There are many reason's to use trailers!!!
But, most of the time that trailers are on the horse is because the
farrier doesn't have the right size and doesn't want to take the time to
cut the shoe to the right size.
The heel chalk's will stop rotation. The trailer with no heel chalk's
will help the hock. Or Stifle.
Sickle hocked horses will benefit from the trailers because it puts the
center of balance father back on the foot. The trailer going a little
farther back will put the balance of the hoof farther back, which takes
the strain off the hock.
There are many reasons to have trailers on the back hooves. So most of
you are right about the trailers.
But, riding out on the trails you have to be careful of roots of trees,
rocks, and things like that, because the trailers can get under the
roots or rocks. Very dangerous.
Don't have trailers on the horse unless they REALLY need them.
