Dealing With A Herd - Bound Horse

If your horse is herd bound and gets stressed
out whenever you try to separate him/ her from the herd the
 best thing you can do is gradually wean the horse from the herd.

This is very similar to weaning a foal. Start slowly
by taking the horse a short distance from the other horses
for short periods of time.

Each time lengthening the time and distance.
 Soon you will be able to go on short rides with no problems.
Just keep in mind that slow training is training that
will be remembered in good ways by your horse.
