Laminitis: Part 2
Treatment and Prevention
By Lauren Lamb
As mentioned last month’s OKFR article, the key to having a successful outcome in a horse with acute laminitis is rapid diagnosis and aggressive therapy. As soon as you notice your horse displaying the clinical signs of laminitis (heat in the front feet, increased digital pulses, walking on egg shells, rocking back on their hunches when turning, etc.) a call should be made to your local veterinarian. The faster you contact your veterinarian and institute therapy, the less damage that will incur to lamina in the hoof and the better chance the horse has to make a full recovery.
Laminitis is usually caused by some other disease with in the body—severe infection, grain overload, grazing on fresh green grass in the spring. The key to therapy, for laminitis, is to identify the underlying cause of the infection or inflammation and initiate therapy towards the disease. An example of this may be a horse with a severe pneumonia, which needs to be administered antibiotics, anti-inflammatory medication, IV fluids, etc. Another example would be administering mineral or activated charcoal to a horse that has overloaded on grain. The mineral oil or activated charcoal will absorb the excess carbohydrates and/or toxins within the colon and prevent them from being absorbed into systemic circulation.
Equally important is the prevention of further damage to the lamina. Treatment directed towards the lamina includes icing the feet, especially within the first minutes to hour of noticing clinical signs. Putting your horse in a stall with deep bedding of sand or fine wood shavings is another therapy directed toward protecting the lamina.
Sand is the best bedding for horses with laminitis. The sand will mold to the bottom of the horse’s foot, which will help relieve some of the stress on the horse’s hoof wall. Administering an anti-inflammatory such as Bute is also indicated. The Bute will help relieve some pain as well as protect the lamina from further damage secondary to the inflammatory cytokines. Your horse should be taken off all feed, especially feeds that contain molasses or complex carbohydrates. Generally, horses with laminitis can be fed free choice grass hay.
Hoof care is another critical branch of therapy for a horse with laminitis. Within the first few days of a horse developing laminitis, your veterinarian will work with a farrier to place a support shoe on the horse. This support shoe will transfer the weight from the hoof wall to the sole and frog of the foot. The support shoe is a better long-term remedy for a horse with laminitis compared to putting a horse in a stall with deep bedding of sand or wood shavings.
Prevention of laminitis
Laminitis is a painful and debilitating disease. Prevention of laminitis is always better than trying to cure the disease. One good prevention technique is to recognize horses that are predisposed to developing laminitis. Horses with endocrine disorders (equine metabolic syndrome or, Cushing’s disease) are more prone to developing laminitis than the average horse.
Horses with equine metabolic syndrome are considered easy keepers. They will also have regional fat deposits around the tail head, crest of the neck or behind the shoulders. Horse with Cushing’s disease can have similar clinical signs as a horse with metabolic syndrome, plus they will have long, coarse hair coats that do not shed in the summer.
Horses with these endocrine disorders should be fed diets low in starch and high in fat and fiber. Equine Senior feeds are good examples of a feed that is low in carbohydrate and high in fat and starch. Also feeding these horses several times a day helps to mimic the natural feeding habits of a horse. Horses with endocrine disorders need to be placed on medication to help stabilize their hormone imbalances. Consult with your veterinarian to decide which medication you horse may need.
Another potential cause of laminitis is severe systemic inflammation or infection, which can be seen in mares with a retained placenta. The mare should pass her placenta within one to two hours of parturition. If the mare has not passed her placenta in this time, you should contact you veterinarian as soon as possible to initiate therapy to get the placenta passed.
Using black walnut shavings as bedding is also a known cause of laminitis in a horse. This type of bedding is uncommon in Oklahoma and Texas and usually is not an issue.
Overloading a limb secondary to a severe lameness in the opposite limb is a known risk factor for laminitis. The horse will develop laminitis in the limb that is being overloaded. This is also known as support limb laminitis. The reason the weight bearing limb develops laminitis is unknown.

From a Kid’s Horse Point of View – Western Housewives
By Summer McMillen
As the land starts to thaw and cowboys and cowkids everywhere are gearing up for spring there is one specimen in particular that is dreading the coming season. And that is ponies. Or more specifically, kid horses.
Let’s look at life from the kid horses point of view for a second.they have the winter off. They’ve gotten to enjoy some much needed R&R in the back pasture. Their hair has gotten long and so have their hooves. They’ve spent the winter feasting on native grasses, alfalfa, and the occasional bucket of grain when it’s was especially cold.
They’ve gotten to wonder aimlessly while the real work horses were still being caught for essential tasks. The most work these kid horses have had to endure the last few months were being tied to the arena fence to get the cockleburs brushed out of their tail.
Yes, life has been calm for these kid horses. But, there is a season for everything and the season for being used and abused is fast approaching.
My own children all share a little pony they affectionately call “Rubble.” He is a certified welsh pony that is as tall as he is wide and is as passive as he is…not. They spend summers riding him bareback. And when they aren’t riding him bareback they are riding him fully saddled. Tiny little bit in his mouth being yanked in every which direction.
The little fellow takes everything in stride. But I can feel him starting to resent me from the back pasture already. Every time I carry him some feed he gives me a look that just screams “please keep all three of your children away from me forever please.” I laugh at him and tell him he doesn’t mean it and then he runs away as fast as he can. It’s a special bond.
Kid horses are funny like that. We entrust them with the lives of those most special to us. We saddle them up and throw the little cowkids on them and assign them small tasks like moving 200 pairs to a new pasture or, holding the herd while dad doctors wheat cattle. More often than not, the young partners get their job done. Sometimes in unlikely ways.
Last summer my daughter hopped up on Rubble bareback and was going to trot down the road and get our mail. A simple and harmless task I thought. I was proud of her for taking the initiative. I was also proud of her when I looked out the window, saw the little pony start crow hopping with excitement and the unassuming 8-year-old being catapulted in the ditch. Instead of crying she climbed back on. Tenacity, I thought. That’s what kid horses are good at teaching.
A few months later I was watering all our geldings. The three kids whom I raised, better known as the three amigos, were all harassing the little pony. My youngest son decided it was his turn. He climbed up on Rubbles back as proud as a peacock. But, he couldn’t help himself. He wanted to look that pony in the eye. So he starts leaning. Farther and farther until he leaned all the way to the ground. Lost a boot in the process. Instead of rushing to his side I waited for the tears. He was only two years old at the time after all. Instead his face was filled with glee. Joy, I thought. That’s what kid horses are good at teaching.
My middle boy is afraid of heights. So mounting a horse has been tough for him. When we introduced Rubble, I wasn’t sure he could even manage his height. After a little encouragement he donned his chaps, boots, and hat with a turkey feather in it and mounted the little horse. In a matter of five minutes the little cowboy had rubble trotting around the arena with his hand in the air and his spurs in his neck. (Gently of course.) Confidence builder, I thought. That’s what kid horses are good at teaching.
While, most of the time kid horses are a nuisance. Eating all our alfalfa and requiring special horse shoes to function properly.. they are more often than not a priceless gift. Teaching the ones we love most how to have tenacity, joy, and confidence.
While the ponies in our life may love their time off in the winter you can’t convince me that they don’t love their jobs in the spring. Even if it’s just a little bit. When that little cowboy shoves a bucket of grain in their face after a job well done together, the ponies head sits a little higher and so does that little cowboys hat.

Foot Abcesses in Horses
By Garrett Metcalf, DVM
A foot abscess is a common occurrence in horses throughout the year, with wet weather often contributing to an increase in cases. These abscesses can cause significant pain, lameness, swelling, and overall misery, making it important to address them quickly and manage pain to keep the horse comfortable. There are various methods used to treat foot abscesses, and this article will outline techniques to evaluate and treat them as efficiently as possible.
A foot abscess is a localized or sometimes diffuse infection trapped between the sensitive and non-sensitive laminae within the hoof capsule. Abscesses may develop spontaneously due to everyday stress and environmental factors that allow bacteria to penetrate down to the sensitive tissues. Other causes include penetrating injuries to the sole from nails, sharp rocks, or even thorns. Poor hoof care and misdriven shoeing nails can also lead to abscess formation. Common sites include the white line, where the sole and hoof wall meet, and the bars of the heels.
The level of lameness caused by a foot abscess can vary, but it often results in visible discomfort at the walk and can even cause non-weight-bearing lameness. Swelling that begins at the foot and moves up the leg may occur, particularly if the abscess migrates and ruptures at the coronary band. These cases are often referred to as “gravel” abscesses, which are simply abscesses that find the path of least resistance and exit at the coronary band, creating a draining tract. In some cases, especially involving a hind foot, the horse’s movement may appear so abnormal that it mimics neurological issues, confusing owners and veterinarians.
Diagnosing a foot abscess begins with a lameness exam. Most affected horses will be visibly lame at the walk, though in some cases a trot may be necessary to detect the issue. Regional nerve blocks can help confirm that the pain is originating from the foot and not another part of the limb. Horses with abscesses often show an increased digital pulse and, occasionally, noticeable heat in the foot. The bounding pulse is due to inflammation and is most easily felt just above the hoof near the ankle. If the horse is shod, removing the shoe is often necessary for a thorough exam. Hoof testers are useful in identifying the most painful area, and horses with abscesses are typically reactive to pressure. Cleaning out the foot with a hoof knife is important for exposing any defects or tracts in the sole or frog. Often, a dark spot or line will lead to the source of the abscess.
There are multiple ways to treat an abscess, and opinions vary widely, but my preferred approach is to open the abscess as soon as possible. This provides nearly immediate relief for the horse and allows the infection to begin resolving. A sharp hoof knife or loop knife is a reliable tool to open the abscess and create drainage through the bottom of the foot. Allowing the abscess to drain from the sole reduces the risk of a gravel abscess and makes it easier to treat the area with topical poultices. After opening, it’s important to bandage the foot both to draw out remaining infection and to keep the area clean.
A large baby diaper makes a simple, effective bandage. It’s absorbent and fits the hoof well. Secure it with layers of Vetrap, duct tape, and Elastikon, or place the hoof in a medicine boot to keep it protected. Poultice choice is often based on personal experience and availability, but the goal is the same — to draw out infection and prevent contamination. Products like Magna Paste, an Epsom salt-based poultice, are effective, as is a homemade mix of sugar and Betadine. There are many other options, but whatever product is chosen should be safe and offer antimicrobial properties.
In some cases, an abscess may be difficult to locate or open. Soaking the foot in warm Epsom salt water can help soften the hoof and encourage the abscess to rupture or become easier to identify. Pain management is also helpful while waiting for the abscess to surface. If the abscess continues to recur or proves difficult to treat, radiographs can help evaluate the hoof’s internal structures. While most abscesses don’t show up on X-rays — since the fluid is the same density as the hoof — they may be visible if gas is present within the abscess. Radiographs are especially important in cases of puncture wounds, to ensure deeper structures like the coffin joint or navicular bursa aren’t involved. In cases of penetration, it’s best to leave the foreign object in place until X-rays are taken, which helps determine the extent of the injury and what structures may have been affected.
While preventing all foot abscesses isn’t always possible, good hoof care goes a long way. Regular trimming on a consistent schedule helps maintain healthy laminae and prevents stretching of the white line, which can allow bacteria to enter. Careful shoeing practices, including proper nail placement, can further reduce the risk of abscess development.
Foot abscesses are painful, frustrating, and often sudden — but with proper diagnosis, drainage, and aftercare, horses typically recover well and quickly return to soundness.

The Pull of the Barn
When I was younger, I saw plenty of old Westerns. They were fun to watch, but one part always stressed me out. Inevitably, a cowboy would get shot or thrown from his horse, and while the cameras stayed on the fallen rider, I worried about the horse. Would it wander around lost on the prairie, never finding its way back? The truth is, most horses know exactly where home is. Turn one loose, and it will drift toward the barn. Ride one out, and the trip away from home feels steady, but the return picks up pace the moment the barn roof comes into sight. We even have a name for it: barn sour.
Horses are prey animals, and survival has always depended on familiar ground. For a domestic horse, the barn means food, water, and the company of the herd. Ethologists (scientists who study animal behavior) point out that horses are quick to learn patterns. When hay and grain appear in the same place every day, that spot becomes magnetic. Over time, repetition lays down mental trails as clearly as cattle wear down physical ones in a pasture. What appears to be stubbornness is actually instinct. The barn equals safety, and safety equals survival. Riders from cavalry days to modern ranches have written about horses quickening their pace on the way home. And though the land changes, that pull never does.
People are not so different. We all have barns in our lives — comfort zones we gravitate toward, routines that steady us. They serve a purpose. Like a horse standing at the gate, we lean on safe ground when life feels uncertain. But the pull can also hold us back. A horse that refuses to leave the yard never discovers what lies beyond the fence, and the same is true for us.
That balance shows up in history too. Old cattle trails once served their purpose, guiding herds north and helping to build economies. But when railroads and fences changed the landscape, those well-worn tracks became ruts. Progress required new paths. Our own habits work the same way. Some keep us grounded. Others only circle us back to where we started.
When I see my horses drifting toward the barn, I think less about impatience and more about instinct. They are drawn to the familiar, and so am I. The barn matters. It is the anchor point, the place of rest. But the pasture matters too, because growth is waiting outside the gate.
Those old Westerns had it right in at least one way. The cowboy’s horse was never going to wander off aimlessly. It would head back to camp, back to the barn. That simple truth still plays out in every pasture and arena today. Horses know where home is. The question is whether we will let the pull of our own barns keep us tied too tightly, or whether we will use them as a base to step farther into the wide-open ground ahead.
