When I am evaluating a behavioral issue in a horse it is usually because the trainer cannot fix a problem.  Problems such as a horse bucking, refusing to go forward , spinning out from under the person, grinding teeth or head flipping are common behavior issues with common causes.  But the in order to truly fix the problem, the trainer must understand more about the horse’s natural behaviors, learning ability, communication and intelligence. Trainers often do not have time to spend with horses, especially if they are at a horse show and need to get the horse ready for a client to ride
