I was awarded the lifetime achievement award at the January 2015 IAED  meeting in Fort Worth Texas.  Karl and I continued on to Eastern Texas after the meeting where we visited a ranch and picked up fifty to sixty skulls that we later boiled and entered into the school library.  April and June classes have been full with great participants.  Our next scheduled classes are slated for 

October 2015.  Dale Jeffrey, Principal

I will be at the International meeting in Texas, 2016.     Dale Jeffrey

Equine Gnathology Defined

Equine gnathology is the study of masticatory systems, including their physiology, functional disturbances, and treatment techniques. Gnathology requires extremely accurate equilibration and prophylaxis, verifying the work as it progresses, applying all well founded neuromuscular gnathological principles, and rechecking the work continually.   

The heart of equine gnathology revolves around efficient comfortable mastication and optimum performance.

Because equine gnathology is not generally a part of veterinary or dental school training most is learned through and from experienced mentors.  

April Gnathology Class 2012

By Steve Sampson

The Gnathology Class for April, 2012 has just finished.  There were six students from across the United States and there was even a student from Israel.  The first week was spent studying anatomy, theory, mastication, equilibration techniques, and the interdependent planes of occlusion of the incisors and molars.

I arrived on the last day of the lecture series, met the students and began to become familiar with them.  They were all well versed in horsemanship with a variety of expertise in divers disciplines.  Although the variation was obvious, the common thread that bound them together was a desire to learn and succeed in the coming practical application phase of their newly acquired knowledge.

There was an obvious feeling of excitement and apprehension about the upcoming week.  I had several private conversations that helped reassure a few of the students in their moments of self-doubt.  I think it helped to hear from an old-timer that Dale and Bert are not only the most competent and patient technical instructors, I had ever met, they are both compassionate men who will put forth every effort to teach these students the principles of practical Gnathology.

Robert and Chuck, both of whom are farriers, spent the weekend trimming and shoeing Dale’s herd of horses.  I joined them and did some fire work with the shoes.  We compared notes and had a great time together.

Chuck and Dennis worked with some young horses that were yet to be started and within a few hours they were riding them in the corral.  They each rode one of the horses they started on a student trail ride in the high desert above the Snake River that weekend and their horses did as well as the seasoned horses. 

Both of these young men, obviously had backgrounds in starting young horses and employed their techniques with little or no trauma to the horses.  The students and instructors were all impressed with their ability to start young horses.  

Carl and Travis, a pair of young stockmen, and I, put on a demonstration of breaking yearling steers to the yoke and harness by driving one of Dale’s future six-up Brown Swiss oxen in a Red River Cart.  The students enjoyed the unique demonstration and began to appreciate the difference between oxen and horses.

All of the activities helped alleviate the apprehension over the upcoming week in the wet lab.

Dale mentioned to me that the students took it upon themselves to start the young horses and work on the hooves.  He also noted that they did everything as a group.  They cooked  and traveled together, and they supported each other.  Dale figured they were a special group and that we would see some unique work during the coming week.  We were not to be  disappointed.

Monday morning started with typical confusion and frustration, the students were trying to work with un-sedated horses and were experiencing the normal resistance.  At a certain point, Dale, Bert or I would step in and show them that it was not the horse’s fault; the problem was within their own technique and attitude; since, the ability to work with un-sedated horses must be initiated from within the heart and mind of the human.  


Turning the seemingly difficult horses into willing patients who wanted to receive Gnatholoy treatment opened the eyes of the students and put them in the frame of mind to really absorb the principles of advanced horsemanship that are required to work with un-sedated horses.

The new float blade receiver design, (that I can say with pride that I came up with on my last trip), proved to be a tremendous advantage in floating horses with sore cheeks and tongues.  The horses seem to actually appreciate the difference, as if it is an act of kindness.  The practitioner will now find he will be able to float many more horses without disturbing the areas that have been previously traumatized; thus many horses will be less reactive during simple equilibration procedures.


The students began a steady advancement in equilibration techniques and analysis of the different malocclusions by Monday afternoon.  On Tuesday morning they had sore muscles and an appreciation for the technical aspects of identifying problems, of making the correct adjustments, and of how to leave the mouth in a state of balance for maximum feed conversion, equilibrium during performance, of how to optimize the bridle response, and of what is required to accomplish these objectives with minimal trauma to the mouth.  With each passing day the students gained a greater grasp of these concepts; their progress could be judged by their questions.  By Thursday and Friday, the instructors needed to reach a little deeper to come up with answers to some thought provoking questions.

It was satisfying to watch the students advance and know that some of the horsemanship of the past is being passed on to the younger generations.  Thus horsemanship will have a chance to survive in a day and age, when the public is all too quick to rely on sedation, instead of horsemanship to work on horses.  There are now six more people who know there is another way, and they will influence hundreds more with their newly acquired skills.


To those six students, I must say, congratulations for putting forth such effort, I am sure your efforts will be rewarded, not just in monetary terms, but more importantly in realizing you now have the ability to improve the lives of thousands of horses.

August 2012 Class  

We have just completed a successful August class.  Seven students attended with Mike Degner certifiying on three horses.  


Bert and I ran five classes in 2013.  It seems like we have been going non stop for quite some time.  Our next classes start in April of 2014 and it looks like we will be booked full for the year.  We have more reasons to be grateful than we can count.  

Dale Jeffrey, Principal  


We have just finished our Sessions for 2014 ending with a great class and field trip around Southern Idaho.  

Thank you everyone for your participation.  We hope to see each of you again soon.
