Up until this point I have very purposefully avoided writing about the subject of equine nutrition. The equine industry is full of fancy marketing tactics by feed manufacturers and it seems a lot of people have been brainwashed into thinking that they must feed their horse a specific bagged "grain" in order for their horse to be healthy and thrive. A question I hear often in my trimming practice from horse owners is what type grains they should be feeding their horse. My answer is always why do you need to feed grain? Its sort of a loaded question, some horses have high nutritional requirements and can benefit from added grains, but others don't need them at all so its never a cut and dry answer.

By now if you have read my writings or followed me on social media you should know that I like to encompass a holistic approach when it comes to my horses. This naturally carries through for me when it comes to feeding them. I prefer a forage based diet with as little processed food as possible. Horses by nature are grazers, they should spend 16 or so hours a day browsing around for food a bite here and a bite there - a constant stream of forage into the digestive system. But what we need to understand about that is that they are not grazers in the sense that they should be grazing lush grass pastures for 16 hours a day, mouthful after mouthful of lush sugar laden green grass. 

The equine digestive system requires a delicate balance. Too many carbohydrates (sugars) and you can end up with systemic issues such as insulin disregulation and laminitis. Too little forage and you can cause irritation in the stomach and create ulcers and imbalances with the healthy digestive bacteria. Too little protein and you will see muscle wastage and protein deficiency, too much protein and you could cause damage to the horse's kidneys and liver. By now you might be able to see why I have avoided writing about nutrition.

What happens in domestication is that we commonly overgraze our pastures, either by having too small of a space of the number of horses we have or by not rotating the horses in order to give the grass a break. This cycle usually sees the pastures with tall dense green grass in the springtime and early summer and then as the summers goes on this grass becomes overgrazed creating high stress levels in the grass and root systems, even worse then the tall lush grass of spring. The horses often favor this short grass because it is higher in sugar and more palatable. If you have ever walked through a horse pasture you will have seen clumps of tall grass that the horses will avoid, instead they tend to prefer the very short grass with the root systems exposed. This is because the tall grass, still full of carbohydrates, is usually significantly less carb laden then the short grass and exposed root.

Horses don't always know what food is good for them as they exist on a very primitive level when it comes to eating in comparison to humans. Their brains are telling them that winter is coming and they need to build has much body fat as possible to protect themselves from the harsh cold weather. Their brain doesn't know that they will be wearing three rugs and fed warm mash twice a day as our human brain does. Horses in nature have a very natural cycle of weight gain and loss throughout the year. They build up body fat all spring, summer and fall in order to make it through the harsher winter foraging beneath the snow. This is how the ancestors of our domestic horse are programmed and this programming has been passed down to our domestic horses. They don't understand that they are now living in Florida and won't require those extra calories, they just exist as they are designed to, using those biological instincts to guide them.

So it is then up to us as the caretakers for our horses to provide them with the best possible diet suited to their individual needs. So what does that mean? To me it means keep things simple. Natural is simple for me. I feed my horses forage, good quality hay low in sugar, higher in protein with a balanced mineral makeup and in quantities that keep their body condition in an optimal state for each individual horse. It might sound primitive but if one of my horse starts to look underweight I add more forage, if the are looking overweight I decrease forage. There is no preset percentage of body weight feed ratio that I follow, I visually interpret the results of my feeding program and adjust accordingly. This works well for me for a horse with no health complications who may be in mild to moderate work schedule. Where things can start to get complicated is the horses with compromised health, horses who are performance athletes, old horses, young horses and injured horses. It is also difficult if your hay is not balanced in mineral makeup or may be high in sugar and lacking protein or vice versa. These are challenges we all face and this is where feed companies have found their market. 

So what can we do to make up for a deficit in our hay? To help our aging horse or our compromised horse? Stay tuned for my next blog post to answer those questions and more!

Thrush is something that at one time or another all horse owners will likely have to deal with. It is not a product of neglectful horse care, nor is it a product of unsanitary living environment etc. Thrush is a combination of bacteria and fungus that can eat away at the frog tissue in the hoof. These bacteria and fungus are more prominent in wet conditions and thrive in moist ground, but can also be a problem in dry conditions. In the image above you will see the healthy frog on the right, the thrush infected frog on the left. You will notice that the central sulcus, the area at the rear of the frog in the middle, in the healthy hoof is just a small indent, but in the affected hoof it is a deep crack. This is the first area that thrush usually starts to affect. What happens is the the thrush eats away at the healthy tissue and creates a "home" for itself within the sulcus of the frog. The deeper the crack, the better the hiding spot for the thrush to thrive and eat more healthy tissue. It is a vicious cycle and can be extremely hard to beat once it gets to this advanced stage.

Minor surface thrush is much easier to deal with. Some ratty tags on the frog, or a small infection of the central sulcus can usually be treated with diligent hoof picking and 2-3 times a week topical treatments with Artimud and/or HoofStuff. More severe thrush can take weeks or even months to clear up and can require soaking, booting and even diet/nutrition changes. 

So why is thrush an issue? At the start with a minor case, thrush doesn't really alter the horse in any way. If we catch it early enough and treat it then it is a non issue. If thrush persists and manages to eat into the frog tissue deeper it can cause the horse to feel some sensitivity when loading the back of their hoof and can cause them to land flat or toe first as opposed to heel first as they are intended to land. Horses land heel first in order to use the frog and its underlying structure, the digital cushion, to absorb impact and dissipate energy vibrations. When the horse alters its movement and doesn't land heel first that impact energy travels up the leg into the joints, shoulders/hip and back and causes excess strain on the body. This can create a cascade effect that can significantly affect the performance of the horse and in serious cases can even lead to lameness.

When the thrush eats through the frog and into the sensitive digital cushion it is extremely painful for the horse. The hoof and its outside structures are designed to protect, and are insensitive structures, meaning they do not have nerves and blood supply directly within them. The nerve receptors and blood supply are located within the sensitive structures: the digital cushion, solar corium and lamina. So this means that a minor surface infection of the frog really won't cause much pain, however once the thrush eats into the digital cushion it is in fact an open wound of the horse, and is painful when impacting the ground. The horse then alters their movement to avoid loading the frog as much as possible. This is an issue because of the previously mentioned strain on the body, but also because healthy frog tissue is generated because of positive impact forces, and without the horse loading the frog it won't receive these forces. This creates a long term problem as the frog and digital cushion will atrophy over time due to lack of stimulation and will alter the shape of the hoof capsule. You then have a significant reduction of impact energy dissipation and a horse that is absorbing that impact in their joints, therefore more prone to develop arthritis and other joint related conditions.

The pictures below show you the severity of a thrush infection once it gets into the digital cushion. These cadavers have the outside structures removed and the one on the left has an infection so deep that a hoof pick can be inserted into the crack approx 1/2 an inch. This is a deep open wound for the horse and extremely painful. The cadaver on the right shows a healthy digital cushion with a normal central sulcus without infection.

So what can we do about it? For minor infections treating topically is easy. Your local tack store will have several products available that are designed to kill the harmful bacteria and fungus that cause thrush. ​My personal word of of caution would be to read the ingredients label on those products. What you want is something that will kill the harmful bacteria and fungus, but not the healthy tissue. A lot of commercially made thrush products have ingredients like formaldehyde, formalin, turpentine etc. These substances are toxic to healthy tissues and will indeed kill the thrush but also the regenerating frog tissue. My favorite thrush products are made by Red Horse and are Artimud and HoofStuff.

Think about a deep thrush infection like an open wound on your own skin. Use products that will keep it clean but also encourage healthy growth. Products such as antibacterial wound scrubs used in human medicine, as well as barrier creams and ointments. My personal method for treating for this type of infection is as follows:

• Thoroughly clean the hoof - I use Sole Cleanse to get into and around the crevices in the frog (be careful with a deep infection, it will hurt your horse to scrub inside there, instead use a syringe to flush the area with your cleaning solution). You can also soak in products such as White Lightning or Cleantrax. 

   

• Dry the hoof and apply HoofStuff in the central sulcus of the frog very gently with your hoof pick. Then apply Artimud to the entire frog and collateral grooves. Remember less is more, you do not need to overfill the grooves.

 

• Prepare your hoof boot of choice. Boots will help to keep the frog clean and dry and make sure your horse can't stand with their feet in their urine or manure which will further exasperate the infection. I use my Cavallo Trek boots, with a 1/2 inch thick felt pad inside, topped with GoldBond Medicated Foot Powder. Put the clean and dry hoof, coated in the zinc oxide cream into the boot. Note: to make felt boot pads I buy a 1/2 inch thick felt saddle pad for approx $40 and cut several boot pads out of this pad. It is far more economical then buying individual boot pads and they are machine washable and can be used a few times before they wear out. 

 

• Repeat this process every second day. Continue this regimen until the infection has closed and the frog is sufficiently regenerated. For some horses long term boots can rub or irritate their heel bulbs or pasterns. Make sure you have the right fit of boot and style that can accommodate a felt pad, and I also use the Cavallo Pastern Wraps when needed.

There are many things to consider when determining how long to go between trims. In this geographic area the standard trimming/shoeing cycle is approximately 6-8 weeks. My own scheduling is usually based around a 4-6 week cycle, though I have the odd horse or group of horses that go a little longer.

What I want to discuss in this blog is a much shorter trimming cycle that is favoured among some very successful and highly respected farriers/trimmers that I follow. What I am seeing and learning from them is that a shorter cycle is far better for the horse, and the overall health of the hooves and therefore the body and mind (My whole horse approach to health will be featured in an upcoming article) of the horse.

First lets think about the ultimate goal we have in trimming our horses hooves. For me it is to mimic the wear patterns that are demonstrated by the wild horses of the US Great Basin and other dry desert dwelling feral equines. These equines are clinically sounder then our domestic horses and have virtually no instances of founder, navicular disease and many other hoof pathologies we see so commonly in our domestic horses.

So if we can apply that principle to our trimming, our mandate would be to trim in order to mimic natural wear over varied terrain. So then the correct trim schedule would have to be based on each horse’s individual hoof wear. Because the hoof is in a perpetual state of growth, this means that immediately after trimming the hoof is already replacing that (worn) material that was removed. The goal then should be to allow the hoof to grow to the optimal length and thickness required for that individual horse. It should then be trimmed again just before it grows past optimal to a leveraging state. If it is allowed to grow too long the forces during impact and movement will start to distort the hoof. When trimming we will then have to perform what is called a rehab trim as opposed to a maintenance trim. A maintenance trim means we are just trimming excess length, and that excess has not caused the start of any breakdown or distortion of the hoof. A rehab trim means that we are correcting pathologies or distortion usually caused by excess length.

The hoof on the left shows a hoof that has grown excess length but is still balanced and not distorted. The overall length needs to come down and the break-over needs a new mustang roll, but otherwise this hoof is balanced, a maintenance trim. The hoof on the right is much longer, and has grown out of balance. The heels have moved forward and the toe is stretching forward. The frog is small and narrow and appears diseased in the central sulcus. Not an extremely distorted hoof but a rehab trim, not a maintenance trim.

The shorter trim cycle will prevent distortion and instead more closely mimic natural wear. For most horses the trimming cycle that these farriers/trimmers are finding works best is 2-4 weeks, 3 weeks being the average correct cycle for most horses. It is important to understand that because these trims are closer together there will be less material to remove. On a 3 week trim cycle there would be little need for nippers, it would really just be a rasp to maintain balance and remove the excess and possibly some knife work if the bars or frog needed addressing.

Where this interests me is with a select few horses I trim that are sensitive on hard or rocky ground immediately after a trim for about 3-5 days. Not sensitive in their paddocks or living environments, but sensitive being ridden on unforgiving ground where they otherwise would have been fine. What those horses need is for me to leave a little more material at the trim, but because I won’t be trimming them again for 4-6 weeks if I leave that extra material we are at a point of distortion before the next trim and then we are back to rehab trims as opposed to maintenance trims. However if I could trim less, and then trim the horse again in 3 weeks there would be less instances of sensitivity after the trim and less instances where the hoof gets to that distortion point before the next trim..

This is easy for me to process, however it becomes a challenge when trying to help horse owners to understand that trimming less more often is in the best interest of their horse. For the horse owner it means they are paying for trims twice as often, seeing much less of a difference in the before and after of the trims, and they are having to schedule me twice as often, taking up their valuable time.

My goal is to make this process easy and beneficial for everyone. I have started a pilot project with a few clients where I am trimming their horses every 3 weeks, and evaluating the horses’s comfort levels before the trim, immediately after and at the end of the 3 week cycle. I am also looking for any hoof distortion (if present) in order to determine the optimal length of cycle for each specific horse. I am working on a price structure that includes a reduced cost for horses that are on a maintenance trim schedule vs those that are in a constant cycle of rehab trims. This would make trimming at these shorter intervals more cost effective and because there is less material to be removed the trims would take less time. Ultimately the biggest advantage of the shorter cycle is for the horse. The closer we can mimic the natural wear pattern of the wild horse, the closer we can come to achieving the soundness seen in those wild herds and the virtually non existent hoof pathology that we so commonly see in our domestic horses.

Environment – A barefoot horse’s living environment plays a large role in strengthening their hooves. A horse that lives on soft pasture will have a hard time building the callous needed to ride on a rocky trail without some form of hoof protection. Whereas a horse that lives on hard rocky ground will have no trouble travelling on a rocky trail as his hooves would have already been conditioned to it. Even if all you have for your horse is soft pasture or dirt, adding some river rock around water troughs or in shelters or a favorite hangout spot can be a big help. Exposure to varying surfaces is important in conditioning the hoof and building strength.

Deciding to take your horse barefoot can be a complex decision. While it is greatly beneficial to them to restore natural hoof function, you must make sure you are ready to face the challenges involved with the transition. I suggest you speak with your hoof care provider about the factors mentioned above as well as discuss the overall health of your horses’ hooves and the expected length of the transition period.

Most horse owners cringe at hearing the words Navicular Syndrome. In the past it has often meant expensive corrective shoeing and just trying to keep your horse sound for one more season, inevitably resulting in putting them down. Unfortunately Navicular Syndrome is one of the hardest subjects for a farrier/trimmer to research. It seems that every old text contradicts the next, and every person you talk to has a different understanding of the condition. The good news is that tons of new research is being done, and hopefully the equine world will soon have a better understanding that the best way to treat Navicular Syndrome is to prevent it in the first place, and that it is easy to do so.
 
One of the doctors at the forefront of Navicular research is Dr. Robert Bowker of Michigan State University. I had the pleasure of meeting Dr. Bowker at the 2015 Equine Education Summit hosted by Horse Council BC this past spring. Dr. Bowker states that he has identified a heel first landing as the most important element of hoof function and more importantly hoof development. He has determined that as the hoof impacts the ground heel first, the hoof expands both laterally and from the back to the front, and the concave sole descends lower to the ground, thus dramatically increasing the volume of the hoof capsule. This sudden increase in volume creates a vacuum, which pulls blood into the hoof capsule. This pull of blood not only nourishes the living tissues in the hoof, but acts as a very important hydraulic shock absorber.
 

It has been documented over the years that some horses with navicular bone changes are perfectly sound, while others without bone damage can show severe lameness in the rear of the hoof. This is confusing though as it has long been taught in the veterinary and farrier communities that the bone damage happened first and the pain associated with Navicular Syndrome was caused by the deep digital flexor tendon sliding over the rough surface of the damaged navicular bone.
 
Dr. James R. Rooney of the American College of Veterinarian Pathologists specializes in post mortem studies of horses. In thousands of dead horses he has examined, Dr. Rooney found that the fibrocartilages surrounding the flexor tendon and navicular bone were always damaged if bone deterioration was present. He has not found one single case where the bone was damaged and the fibrocartilage was not. He has however found cases where the bone was not yet deteriorated and yet the fibrocartilage had started to break down. He has learned that the order in which damage occurs is: first the fibrocartilages surrounding the navicular bone, second the fibrocartilages surrounding the deep digital flexor tendon, third the flexor tendon itself, and finally the navicular bone itself is damaged by the rough surface of the damaged flexor tendon. Simulating a toe first landing with cadaver horse legs in test machines, Dr. Rooney was able to simulate this exact process of deterioration, proving the order in which tissues were damaged leading to Navicular Syndrome.
 
The main structure in the front half of the hoof is the coffin bone. The sole and hoof wall are attached to it via the lamina. The digital cushion and the lateral cartilages form the rear half of the hoof. It is the rear half of the hoof that is responsible for dissipating the impact energy of movement. The front of the hoof has no impact absorbing structures, they are all fairly rigid. The digital cushion at birth is made up of primarily fat and is filled with nerves. As the foal moves the pressure and release of the frog causes fibrocartilage to grow from the front of the digital cushion and spread toward the back. By the time the horse has grown to an adult the digital cushion should have transformed into a mass of fibrocartilage. This fibrocartilage is responsible for protecting and cushioning the nerves as well as dissipating the energy of a heel first landing. The lateral cartilages at birth are tiny, less than 1/16th of an inch thick, and don’t extend to the underside of the frog and digital cushion yet. As the foal grows, with movement, flexion, and the expansion and contraction of the hoof mechanism the lateral cartilages grow. They should eventually extend to create a floor underneath the frog and digital cushion and should have developed to about an inch thick.
 
So why are most horse’s uncomfortable landing heel first? Because in domestication we tend to keep our foals on soft ground. Deeply bedding the stalls that restricts their movement, and keeping them on soft terrain when they are turned out. The soft ground inhibits the flexion, expansion and contract and negates the hoof mechanism as it was designed to work. This results in very commonly, adult horses with lateral cartilages as thin as 1/8th of an inch thick instead of the inch they should be, and with digital cushions that are underdeveloped, thin and weak.

Dr. Bowker has also found that bone loss associated with Navicular Syndrome can also be attributed to a lack of natural pressure in the navicular region of the hoof. He specifically blames peripheral loading i.e. shoeing the hoof to remove sole pressure or allowing the hoof wall to grow too long so that the sole, frog, and bars of the hoof cannot share in the weight baring pressures of movement as they were designed.
 
When we learn the science behind Navicular Syndrome, and when this information becomes mainstream, only then can we start to prevent these changes from happening. While we cannot heal the bone deterioration once it has happened, we can bring strength back to the digital cushion and lateral cartilages. We must first bring them back into work, by removing the peripheral loading devices, keeping a low heel and allowing the digital cushion to strengthen again. The digital cushion is filled with myoxoid tissue which is similar to stem cell tissue and Dr. Deborah Taylor of Auburn University has published that the digital cushion can regenerate if given the opportunity. And as discussed previously, horses with bone deterioration to the navicular bone can be made comfortable if the rest of the hoof is allowed to strengthen to support it.
 
If your horse is suffering from Navicular Syndrome or you want to learn more I would direct you to study the research of Dr. Robert Bowker, Dr. James R. Rooney and Dr. Deborah Taylor. They are leading the research right now, and are coming up with amazing information that is helping horses that would have previously been put down.

In last month’s article I discussed the difference between Laminitis and Founder. I explained that laminitis by definition is inflammation of the lamina in the hoof. The lamina affected are the sensitive lamina (surrounding the front and sides of the coffin bone) as well as the solar corium (the underside of the coffin bone). I also discussed that low grade laminitis left untreated, or during acute laminitis, the coffin bone can rotate within the hoof capsule becoming foundered. Founder is simply the rotation of the coffin bone. There is no almost or partly foundered. Either the bone is rotated or it is not. However, the severity of the rotation can vary. This is dependent of the overall health of the hoof prior to the laminitis, the length and severity of the laminitic episode as well as the current trimming/shoeing protocol. In this issue I want to show you what a foundered hoof looks like both inside and out.

In order to demonstrate a foundered hoof, I will first show you a healthy one. The hoof wall is well connected all the way from the coronary band to the ground, it is not flared, pulled forward, or separated.

Published in Saddle Up Magazine July 2015

            The terms Laminitis and Founder are often used interchangeably by vets, farriers, trimmers and horse owners alike, however in my opinion they have two very different meanings. Laminitis is the inflammation of the sensitive lamina surrounding the coffin bone. This includes the sensitive lamina, found along the front and sides of the coffin bone, as well as the solar corium which is found on the bottom of the coffin bone. The sensitive lamina is the vasculature covering the coffin bone and it has nerves and a blood supply. The insensitive lamina is located on the inside of the hoof wall and has no blood supply or nerves and is semi-rigid in structure. The sensitive and insensitive lamina interlock like Velcro. This connection of the lamina supports the coffin bone’s position within the hoof.

            Time is precious and a healthy relationship with your hoofcare provider is crucial to your horse’s wellbeing. Here are a few tips of what you should expect from your provider and what he/she is hoping to see from you.

            Be on time. This works both ways as everyone’s time is valuable. If your appointment is scheduled for 1pm, arrive early to prepare your horse and his surroundings for the visit. Do not arrive at 12:59pm just ahead of the trimmer and rush to halter the horse and scramble to get him ready. Instead have your horse haltered and waiting calmly, perhaps lunged if they are in a particularly anxious mood or have trouble standing still. A trimmers schedule can change throughout the day, so please allow them a little bit of leeway. Perhaps a 15 minute window surrounding the appointment time. Anything more than that and they should call to touch base and see if your schedule is flexible. If you or your trimmer are unable to make the appointment at least 24 hours notice is necessary, 48-36 hours is better, but the situation might not always allow.

            Be prepared. Having the feet picked out is a nice treat and even having the horse lightly groomed should impress your trimmer. I am not stating that your horse be groomed as if they were to beshown immediately following the trim, simply if the legs and hooves are muddy, perhaps curry them off. Your provider likely has several other horses to see after you and would like to stay as presentable as possible. Have your horse on a clean, flat dry surface if possible. A barn isle way, a stall mat, or even just a flat packed dirt area or driveway. Being able to assess the hoof while on the ground is a key component formulating a trimming plan and will make your provider’s job easier. Trying to see hooves in tall grass or mud can be difficult. Your trimmer should also arrive prepared with all of the tools required, and ready to work.

            Stay in the moment. Be aware of your horses’ behaviour while being trimmed. Being firm and fair with your horse is important in keeping your trimmer safe while they are doing their job. Do talk to your trimmer, but also pay attention while holding your horse so that you can alert the trimmer to a potential spooking hazard or you can let them know if your horse is uncomfortable in a specific position. A horse that is moving around and distracted can be hard to trim, so keeping them focussed on the task at hand is important. If you are unsure how to handle the horse in a given situation, ask your trimmer how they would like you to handle the horse while they are working underneath him.

            Communication is key. Expressing any concerns or questions you have regarding the trim is very important. An open line of communication will ensure you are both working in the best interests of the horse. Your trimmer should be open to answer your questions, and also explain how or why they are doing things the way they are if you ask them to. The answer of “because that’s how it’s done”, is not acceptable.

            Payment is due when services are rendered. If you are hoping to pay at a later date or with a postdated check, please consider asking your trimmer if this is appropriate prior to the appointment. With technology today a lot of mobile services are set up to take credit or debit on the spot. However not all have these devices so please check at the time you book your appointment if that is how you intend to pay. Your trimmer should also be prepared to write you a receipt should you require one, and the amount owing should not be more than quoted to you when the appointment was booked unless it was discussed before or during the trim. This occasionally happens if the condition of the hooves require something extra that the trimmer couldn’t anticipate prior to the appointment.

          For many horse owners, evaluating and trimming their horse’s hooves is a task left up to their farrier/trimmer. But how do you know that the person that you have hired is doing a good job? You have to be able to evaluate your horse’s hooves beyond the scope of how sound the horse moves. While soundness in the present is important, the horse’s long term hoof health is also a major factor owners must consider. I see many cases where long term incorrect hoof shape or function has lead to irreversible damage while the horse appeared sound until it was too late to correct. However I also see a lot of horses that I am able to rehabilitate and return to use after a deformed hoof has broken down.

          There are 5 key points horse owners can use to evaluate their horses’ hooves:


        Heel Placement – The heels should be positioned at what we call the baseline. The baseline is an invisible line that runs across the back of the frog and collateral grooves, and in a well-trimmed hoof also aligns with the heels rearmost surface. When heels are allowed to overgrow or migrate forward from this line, the balance of the hoof is distorted and excess stress and tension is placed on the horse’s joints, tendons and ligaments. Long or forward heels can also shorten stride length.

        Frog Integrity – When a horse moves forward, their natural stride should allow them to land heel first. If the heels are in the correct position as mentioned above, the heels and frog will contact the ground simultaneously. The frog’s primary function is to protect the digital cushion. The digital cushion lies underneath the hard calloused frog and is a large pad of fatty tissue. The digital cushion absorbs impact and dissipates energy. If the frog is infected with thrush or bacteria, or underdeveloped from long heels keeping it elevated and not touching the ground, this portion of the hoof’s function cannot be performed. Without the energy dissipation of a healthy frog and digital cushion excess stress is placed on the horse’s joints.

        Wall Connection – A well connected hoof wall supports the coffin bone and allows the hoof to function as intended. The hoof wall grows downward from the coronet to the ground and should not flare or deviate in angle as it descends. A hoof wall that changes its angle part way down the hoof will have a poor connection and decreased concavity in the sole. A disconnected wall can lead to the coffin bone sinking down into the hoof capsule causing inflammation in the sole resulting in sensitive hooves.

There are a lot of interpretations of natural trimming, and every clinician seems to have their own method. What each of these methods have in common is their connection to the wild horse model. The wild horse model is simply a style of trimming based on the wear patterns on the hooves of the wild mustangs in the US Great Basin.

Even though they don’t live the same untamed lifestyle, our horses’ genetics are the same as their wild relatives. Hundreds of years of selective breeding has not changed the genetic makeup of our horses. Science has proven that it takes between 5000 and 10000 years for evolution to change the base genetics of any species. While we do select specific traits to carry forward through our breeding practices, the genetic makeup of our horses is the same.

Is it fair to compare our domestic horses’ hooves to their wild counterparts? This is a question I get asked often, and my answer is yes. “Domestic horses are really nothing more than wild horses in captivity” -Joe Camp

In May of 2014 I traveled to the Steen Mountains of Oregon to study and observe the wild mustangs that live there. What I saw was amazing. Horses with strong, hard hooves, traversing extremely rocky and uneven terrain. They galloped over it as if they were floating. The mustangs were in peak health, muscled and toned and moving with impulsion and vigour. In the approximately 500 horses we encountered, fewer than 5 showed signs of lameness. These horses could traverse terrain that our domestic horses would stumble and trip over even with strongest of hooves and hoof protection. It gave me a great appreciation for how much more our horses could be capable of if only they were not held back by our ideals.

The benefits of natural trimming with the wild horse as a model are many. The most important being that the hoof can expand and contract upon impact with each step. This the primary way the hoof dissipates the energy of impact, it also increases the circulation of blood through the limbs, reducing the stress on the heart. The horse will also have much fewer chiropractic, muscle and joint problems. It reduces the risk of tendon and ligament strain and damage significantly. Many horses started barefoot from a young age will never have to deal with arthritis, navicular syndrome or many of the other hoof pathologies that develop from improper hoof mechanics and function. Rarely are any of these pathologies seen in the wild.

Domestic horses should move functionally the same as a wild horse. They should strike the ground heel first and allow the shock absorbing functions in the hoof to dissipate the energy. Wild horses wear their hooves constantly because of the abrasive terrain that they live on and because they move 20-40 miles every day. Our domestic horses generally don’t get worked enough on varied terrain to wear their own hooves effectively. It is up to us to keep them trimmed and balanced to allow the hoof to function mechanically how it is intended. Because they are anatomically the same, I believe the wild horse makes a great model for trimming our domestic horses.

            We must have realistic expectations however in comparing our domestic horses to the wild horse in terms of their capabilities. In the right circumstance they are one and the same, but to take a domestic horse that lives in a soft dirt paddock and ask him to traverse the rocky terrain of the wild horse would be unfair. We must condition our horses to the environment we want them to perform in. That means that if we want our horse to be comfortable on rocky ground we need to allow him to live on rocky ground. With proper trimming and care his hooves will callous and strengthen and he will be able. In cases where it is not possible to condition the horse hoof protection is needed.

Many horses develop hoof pathologies as a result of improper hoof care, living conditions or ill health and these hooves need extensive time for rehabilitation. In most cases the horses’ comfort level can be improved, it is only in severe cases that pain management becomes the primary focus. You would never see these horses in the wild as they would not survive on their own, it is only with our help that they can be rehabilitated or managed. Ironically if they had been born wild instead of into domestication, it is unlikely they would have been afflicted with these pathologies in the first place.
