Consider Care Even When They are Bare
series By Bryan S. Farcus, BS, CF
The decision to shoe or not is one that is based on an evaluation of
three main concerns. The first being the quality of health of the horses
hoof (i.e. the presence of any deep cracks or extreme distortions of the wall).
The second being a noticeable weakness in the limb-to-hoof connection,
resulting in a lack of weightbearing capacity for the horse (i.e. Collapsed
"urderran" heels, Longtoe / Lowheel syndrome, Club footedness, etc.).
And last, the consideration of the workload. Certain jobs the horse may be
asked to perform may require a particular type of shoe. For instance, a Trail
horse will need traction for those slippery spots, whereas a Reining horse that
moves quickly and slides will need a non-traction type shoe. We will discuss
the various types of traction and their purpose a little later.
Seeing the Signs of Stress
When observing your horses feet there are
some general notes on anatomy you must be aware of.
The single most important point is that you
should realize that your horses hooves are a result of a metabolic
process in his body. This process is no different from your nail growth. Diet
and the type of exercise your horse faces has a direct affect on the growth
process of the bodys horn producing times. If you or your horse become
ill some signs of bodily stress can be noticed. For example, the skin, hair and
horn will become dull in appearance and in extreme cases these tissues may
deteriorate and "slough-off". It has been said that the horses
feet are its barometer and, as good horse owners, we should learn how to read
it. Lets begin by defining what kind of stress can take place. Generally
speaking there are two: metabolic and mechanical.
Metabolic Stress This is defined as
any change to the horses external appearance due to an internal factor.
This can range from a slight raise in the horses body temperature to a
severe allergic reaction. In each of these cases, a minor case will produce a
superficial "ripple" or ring on the outer hoof wall, whereas a major
case will result in a total hoof wall deformity (deep ridges, dished-out walls,
etc.). Such metabolic stresses are not easily detected in their earliest
And for this very reason, such problems as
Laminitis, Navicular syndrome and Pedal Osteitis can be at an acute (advanced
and life threatening) level by the time any actual structural changes in the
horses hooves are noticed. Many unanswered questions about the metabolic
process of horses and humans still remain an enigma. In recent years, however,
practitioners of modern medical research have benefited from the marvels of new
and improved diagnostic equipment. Along with Radiology (images of bone) and
Ultrasonography (images of soft tissues) the advent of a highly sensitive heat
detection instrument called the Infrared Thermograph has made it possible to
detect bodily stress at a much earlier stage.
In a book, The Illustrated Atlas of Clinical
Equine Anatomy and Common Disorders of the Horse, veterinarian Ronald J.
Thermography in the equine practice
is being used more frequently as a diagnostic aid in lameness evaluation.
Inflammatory processes can be identified weeks earlier than with normal routine
clinical evaluations. He then goes on to say, It [Thermography] is not a
replacement for radiological or ultrasonic studies, but it can be an
On an everyday level the stress that you
and I can observe is not of a metabolic type but that of a simpler, mechanical
form. The horses feet should always have certain characteristics, if they
are not present the hoof is said to be under a mechanical stress.
- the external wall should be hard and, if
healthy, should have a shine or "varnish" that acts to repel the
weather and the elements that the horses hoof comes in contact with.
- the sole should be hard as well as
"arched." A flat-soled horse will bruise easily and may require some
- the frog and bulbs must have elasticity. This
means it must be a little softer and pliable. It has been said that the horse
has five hearts one in his chest and hour on the ground. It is important
to mention that the frog must be flexible and expandable in relation to a
healthy wall and sole in order to absorb shock. There is a myth that suggests
that the frog must actually bear the weight of the horse and concuss (hit the
ground first) in order to pump blood through the hoof.
If a frog happens to make contact with the ground before its counterpart, due
to the conformation of the hoof, and the wall and sole are healthy, then so be
it. If, however, a healthy wall and sole were to be cut down to force the frog
to the ground this will actually result in an inflammatory stress that will
only serve to give the horse pain.
Conditions that may contribute to mechanical stress are:
- Hoof walls that are left untrimmed The
unbalanced hoof will appear either in the form of "Dishing" (a
concave, inward wall) or "bullnosing" (convex, outward wall).
- Extreme climates / Too wet or too dry
Hooves will develop vertical cracks. Minor cracks are often referred to as
"sandcracks." They do not penetrate the whiteline or extend up into
the coronary area of the foot.
- Traumatic injury to the hoof wall / bruising
Generally, a blow to the coronary area will become evident a few weeks
afterwards. Not unlike receiving a hit on your fingernail from a hammer. Red
discoloration will appear and a horizontal crack may eventually form where the
horn tissue has been damaged.
- Traumatic injury to the sole / bruising
As in the above scenario, red discoloration may appear. This is a result of a
subcutaneous (below the skin surface) bleeding of damaged tissue.
- Puncture wound / abscess Any foreign
object that is lodged into the sensitive tissues of the hoof will
"fester" or build-up puss in and around the point of the injury.
- Friction-related injuries This relates
to any irritation that results from a constant rubbing of a tissue by another
object. The simplest example of this is relative to you having a pebble in your
boot or if your boots were too small for your feet. The pain created can be
unbearable. This is essentially what can happen to your horse. A stone wedged
between his foot and his shoe can be painful if left for a long period of time.
Also, it could be that a horse was fitted with an improper size shoe. If the
shoe is too short and does not provide good heel protection the edge of the
shoe could cause extreme sole pressure.
In closing, I think Dr. John P. Hughes,
contributing author of University of California-Davis Book of Horses,
summarized it best by stressing the importance of understanding our horses. He
Often quoted was the old Arabian
proverb The outside of the horse is good for the inside of a man. This
is probably even more true today.
On that note, let me add: even though one might
argue that our survival may or may not be dependent upon that of the horse, I
believe we should continue to allow ourselves to be invited to their study and
at the same time remain excited by their beauty.
