Description
If you understand horses, you'll be able to immediately see the differences in a 'clicker horse's gait and carriage. Even horses that have had a hard time in the past grasping basic performance behaviors can excel when clicker trained. There is also a great video sequence and description in which fear of objects on the trail disappears as the horse is clicker trained while on the trail with is rider in the saddle.
