HELP: My horse REALLY connects to other horses when trail riding…

A listener calls in with a question about her horse who gets very worked up on trail rides with too many other horses. She describes how the horse seems to connect with another horse, flicks its head up, and walks as fast as possible.
This podcast breaks down four different ways to look at the things that could be happening here. This includes looking at the events the horse and rider frequently practice, techniques that could be used, and ideas for increasing the rider's effectiveness in communication with her horse.
