Natural Horse Care Bulletin Series

The NHC Bulletin Series includes highly detailed, comprehensive articles about very specific facets of natural hoof care and horsekeeping practices that concern serious practitioners and horse owners. These are “action” articles, intended to help readers think through the issues and to “act” on the information in practical ways. Many were inspired by questions raised repeatedly by horse owners and practitioners who felt that some issues needed more in depth treatment or clarification. Others arose simply because new information, research, and technical breakthroughs rendered them relevant. These bulletins are replete with vividly clear, colorful photographs and line drawings in a striking, professional format.

Bulletin Synopses

#100 HGC: Hoof Growth Cycle. The hoof isn’t simply descending from the coronet in a disorderly manner, it is growing at a genetically driven rate for a reason. #100 explains the meaning of hoof growth rate, or “hoof growth cycle”, how to calculate and use it practically in a program of natural hoof care. (4 pp.) 

#101 Trimming for Natural Toe Angle, Toe Length, and Heel Length. Most hoof care practitioners are either unaware of, or ignore, the hoof’s “healing” angle-of-growth (H°). But therein lies the “secret” of natural toe angle, toe length, and heel length. This groundbreaking article provides a highly detailed method for determining H°, H°TL, HW, and H, known as the "critical measurements" in NHC science. (10 pp.)

#102 Supercoriaitis: Laminitis Redefined. Current epidemic levels of “laminitis” seen around the world are compounded by our very definitions of what this word is alleged to mean. In fact, the term “laminitis” is essentially incorrect, incomplete, and misleading, #102 lays out an alternative conceptualization for the age old hoof disease — and a new definition. Until practitioners and horse owners accept the fact that laminitis is not what they think it is, horses will continue to succumb and die from it in staggering, ever-increasing numbers. (10 pp.)

#103 The Supercoriatic (Laminitis) Pathway. Having redefined the term laminitis in #102, the disease itself is traced to its causality and destructive path. #103 clashes with the diagnostics, treatments, and prognostications of laminitis offered up by our veterinary community. The pathogenesis of laminitis need not be an incomprehensible labyrinth leading to breakdown or euthanasia. The path is a “straight arrow” from prevention to cure.” (8 pp.)

#104 Trimming the Supercoriatic (Laminitic) Hoof. #104 describes how to adapt the natural trim to the laminitic hoof. (14 pp.)

#106 Rules of Rasping: Eliminating Wall Flare and Splits, and Run-Under Heels. Newcomers to NHC harbor many questions concerning capsule flare, splits, and "run under" growth and how they are remedied through the natural trim. As with the Supercoriatic (laminitic) hoof, the "key" to success lies in "ignoring their pathology" and conducting the natural trim according to NHC guidelines. #106. shows the way. (18 pp.)

#107 The Correct Mustang Roll. #107 illustrates how to render a natural “mustang roll” based on wild horse hoof wear patterns. The mustang roll represents a clear departure from many of the conventional ways that farriers (and vets) turn the hoof wall: rolled toes, squared toes, etc. But many aspiring NHC practitioners also overlook the nuance of the mustang roll — there is no intent to render it unnaturally, rather the manner in which it is often rendered is simply wrong from the perspective of the wild hoof model: the angle of the roll may be too sharp, or commenced and terminated in the wrong place. Commonly, it is executed so that it looks great, but is done at the wrong point in the natural trim process with the detrimental effect that natural thickness of the capsule is compromised. The hoof may then develop splits and other unnatural wear patterns. (18 pp.)

#108 A New Mechanistic Theory: Time and Mass In A 4th-Dimensional Hoof Mechanism. #108 provides a new model for how the hoof not only moves through support, but also how its mass changes over time. The model is contrasted with the European hoof mechanism model that has prevailed in the horse using community for over a century, but which is contradicted by wild horse research.  In a world where the horse-using community demands “instant results”, often at the expense of the horse, the 4th-Dimension Mechanistic Model may prove to be a startling wake-up call for greater patience and an appreciation of not so visible mechanistic forces. (8 pp.)

#109 The Holistic Horse Trim: Finding the Natural Hoof Within. The fate of the natural trim lies in the holistic approach to hoof care. The number one complaint NHC practitioners cite in their work is the horse owner who fails or refuses to correct unnatural horsekeeping practices that undermine their work. This bulletin lays out a conceptualization of NHC that can be shared with clients to facilitate a more cooperative relationship based on understanding of the wild horse model and its applications in the field. (8 pp.)

#110 The Supercorium. Foundational discussion of the dermal structures -- collectively called the Supercorium -- which produce the capsule and horse-to-hoof attachments. #110 provides a totally new way to look at the horse's foot. Within is a living, breathing entity that not only produces the capsule, but is fully capable of "communicating" with us through its vast nerve bed. The choice is ours: ignore it or learn to speak its language and become better practitioners. This may be the most revolutionary and controversial treatise on the natural hoof yet. A must for any serious student of natural hoof care. (20 pp.)

#111 Does Horseshoeing Cause Hoof Contraction? Study about the effects of shoeing on hoof mass carried out over a 3 to 4 year period. #111 calls for a redefining of the term "hoof contraction", including its alleged relationship to lameness. This bulleting should be studied in conjunction with #108. (8 pp.)

#113 Hoof Mass, Motion & the Mythos of P3 Rotation. Counters current thinking and hysteria over P3 rotation and penetration of the solar dome amid a new weight bearing theory.
