Jun 21, 2016 | Athleticism, Farriers, Hoof Care, Lameness
This weekend I learned why I am best suited to my supervisory role here at the clinic. I monitored while Dr. Lacher worked closely with a farrier to determine the best treatment for a horse with a bunch of issues in her feet. I marveled at the way in which they worked as a team, batted around each other’s ideas, and came up with solutions that addressed all the issues. It was like watching TV in a foreign language. As a cat, I am not a team player. Heck, Teannie and I can barely get along. Turns out you need a team to manage your horse. High performance, senior, or just for fun. All horses seem to require a team. Not cats. We only require staff that will jump at our every request. I feel I have trained my minions well.
Anyway, Teamwork. Turns out teamwork is very important for performance horses. There is often a trainer, owner, veterinarian, and farrier at the very least. Trainers and owners need to feel comfortable talking to their veterinarian and farrier about how the horse is performing. It may be something as minor as a lift of the head in a transition one way, but not the other. Based on a trainer’s description of the problem, our Dr. Lacher will put her detective hat on and start investigating. Dr. Lacher uses her 30+ years of horse experience alongside her veterinary knowledge to help track down the source of pain. (We won’t tell her I talked about her 30+ years)
Treatment and rehab come next on the list. Again, teamwork is critical. I really don’t understand why there has to be all this teamwork. I would just impose my will; no questions allowed. Veterinarians today have a wide variety of therapies available. Joint injections with steroids are the most common treatment used. Problem is, those steroids come with some side effects. Hocks handle those side effects well, and can be repeatedly injected. However, every other joint doesn’t. Every steroid injection takes a little tiny bit off the end of a horse’s career. This means careful discussion with everyone involved to determine if injections will help the horse get better faster and cause less damage than the injury they have. Maybe some of the new, crazy advanced therapies like stem cells and platelet rich plasma should be used instead. Maybe rest and targeted exercises should be used. All of that has to be talked about and factored in. With all this talking, I’m going to need more nap time. And more food.
One of the biggest collaborations happens between our Docs and farriers. With the utterly ridiculous design horses have for feet, they need constant attention. Lots of horses need special shoeing to keep those feet comfortable or to help them heal from an injury. Our Docs use radiographs (x-rays) to help farriers line up their shoes perfectly. There is also a whole lot of discussion that goes on about what the Docs have found out from their exam and what the farriers think. There’s always tons of communication going on. I try to make sure I am nearby to assist with this process.
It can be a challenge to determine the best, right thing for these crazy horses sometimes. Making sure you have a winning team sure makes it easier. Until next week.
May 24, 2016 | Abscesses, Lameness, Leg issues
Ah May…It’s hot and dry, then we get rain, then it’s beautiful out but dry. Last year was weird with all the rain. This year seems more like the days I remember as a young kitten. Turns out this weather is fantastic for making hoof abscesses. And while those are fun for the Docs (they have an unnatural love for pus), they are no fun for you or your horse.
I realize I talk about the stupid design of horses a lot, and here I go again. That hard hoof wall is great for walking on but it makes it extremely painful if there is any swelling of the soft tissues inside. Hoof abscesses form when a tiny bit of bacteria get between the hoof wall and those soft tissues. The body reacts to the bacteria by sending white blood cells to kill the bacteria, and, Voila!, pus. The white blood cells also release some chemicals which cause swelling and pain all on their own. All that extra stuff stuck underneath the hoof wall hurts worse than whacking your thumb with a hammer. I do love when humans do that. I laugh every time.
Abscesses usually make their presence very well known. Much like when I sleep on the computer keyboard, you can’t help but notice your horse is not right. It may start as a limp on one leg, however, they always progress to “Holy Cow I can’t stand on my foot!” Once they reach the Holy Cow stage they are ready to be opened. You can get them to this stage faster by soaking the foot daily in warm Epsom salts for 5-10 minutes. This often goes about as well as bathing a cat so may I suggest the baby diaper method. Take one baby diaper (Newborn – size 3 depending on the size of your horses hoof), place a small amount of Epsom salts in the baby butt area, add enough water to make it pasty, place diaper on foot, securing convenient tabs around the pastern while you grab duct tape, run duct tape across the bottom and around the hoof to secure the diaper. Change this daily.
Our Docs can help the whole abscess process get done and over quicker. The closer your horse is to the Holy Cow it hurts stage the more likely they are to open the abscess. Dr. Lacher or Dr. Vurgason will start by cleaning the bottom of the hoof, then applying hoof testers. Hoof testers are these incredibly barbaric pinchy things that help the Docs find the sorest spot on the hoof. Once they find it they will use a hoof knife to pare the hoof away and open up the affected area. They will dig a bit but don’t be surprised if they stop before they open up the abscess. This can be tricky thing. If you dig too deep you can create more problems so the Docs tend to be very conservative. Like I said earlier, they do love to pop an abscess so rest assured they are going to try as hard as they can to get it opened.
The good news with abscesses is that, almost always, once they are opened and drained your horse will return to happy and comfortable. And now back to napping in the sun in the handicapped parking spot. Pretty sure they put that there for me.
Aug 24, 2015 | Allergies, Coughing, Lameness, Laminitis, Leg issues
Please be sure to check your trailer floor for rotten areas. Many of you saw this horse on our Facebook, Instagram, and Twitter feeds. Dr. Lacher and Charly pieced him back together and now begins the healing. He is looking at several months of bandaging but with some luck he will be back to good soon.
Main Topic:
The sun is just peeking over the horizon in the morning as you head out to feed your horse. You open the feed can, scoop out the morning ration, and dump it in the feed bucket. As you walk away you hear a dry, raspy cough. “Probably just the dusty grain,” you think and remind yourself to ask Springhill Equine about it the next time they come out to the farm. What does that cough really mean? Allergic airway disease.
Allergic airway disease has had a bit of an identity crisis over the years. It has been called: Heaves, asthma, Chronic Obstructive Pulmonary Disease (COPD), heaves (again), and currently Recurrent Airway Obstruction (RAO). All of these are our fancy names for constriction of the small airways in the lungs due to allergies. The allergic response causes an increase in mucous in the airway and makes the muscles around those same airways tighten up. It’s an unfair combination which makes it very difficult to breath.
So why the dry cough? These horses typically breathe in fairly well but can’t breathe out without pushing extra hard. We call this abdominal breathing. One way these horses manage to get a good breath out is by coughing. The other thing that leads to coughing is called airway hyper-reactivity. This means anything that touches the airway causes a coughing fit. Dust from grain and/or hay is the most common cause of coughing at feeding time for allergic horses.
Recently there has been a lot of research on these allergic airway horses. Sadly much of it has not progressed to finding new treatments, but we are learning more about the genetics behind allergies, what different symptoms mean, and how well currently available treatments do work. Most older research focused on the effects of allergic airway disease on the racehorse only. Here are the highlights of a few recent papers. If you hear your horse coughing on a regular basis chances are very good they have allergic airway disease. Allergic airway horses are statistically way more likely to have hit this wonderful genetic trifecta: allergic airway disease, allergic skin, and Anhidrosis (non-sweating). Dexamethasone works well in most allergic airway horses but not all. For the horses Dexamethasone does not work on, inhalers provide a safe and viable option.
Treatment is targeted at reducing the allergic response. Dexamethasone is a short acting (about 24 hours) steroid that can be given by injection or orally. Especially during the summer Springhill Equine Doctors will usually start horses on Dexamethasone to get symptoms under control. Typically the dose starts very high and tapers every few days until we find what makes your horse happy. Changes in the weather, pollen levels, and dustiness of hay or grain may require a brief increase in Dexamethasone dosages.
For horses who are unable to tolerate Dexamethasone or don’t respond to it, metered dose inhalers can be used. Steroid inhalers are used most commonly for human asthma. Inhalers present some challenges for horse owners. First how do you get your horse to breathe deeply when you want them to? Answer: you don’t. Second, inhalers can be very expensive and time consuming. To solve the first problem we use an extender which seals over one nostril that allows us to time the “puffs” with the horse’s breathing. For the second problem we discuss options with you, the horse owner, and come up with the best solution.
Once winter comes around Intradermal Allergy Testing can be performed. Allergy testing allows us to identify what allergens bother your horse. Once we know what bothers your horse most we can begin shots, which over time teach the immune system to tolerate those allergens. Allergy shots can offer real help to allergic airway horses but it takes time. It is generally well towards the middle of the second year of therapy before we see benefits. But those are fantastic benefits. We are able to reduce the length of time and dosages of drug therapy these horses are on.
Moral of the story: if you heard a cough, give us a call. The better we control allergic airway disease the longer your horse stays happy, healthy, and ride-able.
Erica’s Corner
Whew! There I did it. I took a breath!!! I am very glad to have Dr. Vurgason here and settled in. It means I get to sneak away to the beach for a long weekend. I am ready for slightly cooler weather so my non-sweater starts sweating again and a little less rain so her constant rain rot can catch a break but such is summer in Florida. The extra breathing room has also meant my two younger horses are getting ridden more. I have seen this as a blessing and a curse all at the same time. I love the way younger horses advance so quickly as they learn the big lessons of life but I hate teaching them! They are sometimes painful lessons for the rider…..

Part 2: Everything You Need to Know About Your Horse’s Feet
So they made me do a little work between blogs but here is Part 2 of my exclusive report from the All You Need to Know About Your Horse’s Foot Seminar.
When you hear ‘break-over’ you should think of thunderclouds parting and the sun coming out, angels singing, a drink of water when you are really thirsty. It’s that important. Horses have multiple break-overs, but we are going to concentrate on the one at the front of the foot for now. A break-over is exactly what it sounds like. It’s the point at which the hoof comes off the ground during movement. The moment of break over is the hardest on the hoof structures. Every bit of that force is trying to tear the foot apart.
A good trim, according to the guidelines I talked about in Part I, will set up a good break-over. This point should be about ½” to ¾” in front of the tip of the coffin bone. Wait a minute… how is my farrier supposed to know where the tip of the coffin bone is located?? I don’t think they come equipped with x-ray vision! Most of the time your farrier will set the break-over at a point about ½” to ¾” in front of the tip of the frog. Sometimes the foot doesn’t seem to be doing what your farrier expects. X-rays of the foot will help your farrier see what the bones are doing inside the hoof. X-rays let us see if there is arthritis, injuries, or laminitis going on which may require special shoeing.
Visual Aids!
Let’s look at some feet and see if you can spot the problem. First up:
This guy definitely doesn’t have his heels back to the widest part of his frog and that’s with the shoe on. And if you look at the branches of the shoe you will see they aren’t even. The shoe is twisted on the foot. His break-over is also too far forward.
Next up:
A line drawn down the center of this foot definitely won’t give you half inside and half outside.
This shoe…..Unless half this shoe was on one foot and half was on another foot it doesn’t make sense.
Now for the fun stuff. What happens when the foot has been trimmed and we can’t get the alignment the way we want it? We put a shoe on it!! So in answer to the barefoot question. Your horse can go barefoot if two things can happen: the foot can be balanced with a trim, and the work the horse is doing doesn’t unbalance the foot faster than it can grow to compensate.
This shoe is an extreme example of break-over manipulation. It starts with a regular shoe. Bar stock is then welded to the inside. Then the shoe is nailed to the foot. The end result is a shoe that allows this horse to break-over anywhere he wants.
This horse is an example of the opposite end of the spectrum. This foot has been allowed to grow long to bring the break-over forward but notice the principles have still been applied. Now this foot is extra long since this horse is due to be shod but notice the foot is balanced and well supported. We can manipulate feet to make gaits we find appealing but it must be done correctly or we jeopardize the horse.
Ever get tired of your young horse pulling shoes? Or have a horse with really sore heels? This shoe, affectionately called the flip flop, fully supports the foot but is very forgiving of the hind foot grab. Most short coupled young horses go through a shoe pulling phase until they learn to wear shoes. It’s normal and should not be blamed on your farrier. Sore-heeled horses need some support since they hurt too bad to not have a shoe underneath them, but metal shoes can be too hard on them. The heels on these shoes offer them soft support.
This shoe is an example of the compromises we have to make sometimes. This horse has a torn deep digital flexor tendon. This injury will heal best if we can take some of the tension off the tendon. A shoe like this helps reduce that tension but it has moved that pressure to the heels. Notice how the heel is curving under. This shoe can’t be used long term without causing significant hoof problems.
A quick note on some common Florida problems. This beautiful abscess is secondary to all the very wet weather we have been having. Using durasole, thrush buster, keratex hoof hardener or something similar on the foot will help it handle all that excess moisture. Sometimes no matter what we use on the foot they just stay way too wet. In that situation shoes may be the answer if only temporarily.
Along with abscesses, thrush is a common problem. The cattle mastitis ointment Today applied to the affected areas daily for a week and then every few days for three weeks will help clear it up. We have also recently started using a product called Keramend on some really really really bad thrush horses and have been very pleased with the results.
Our horses rely on a good foundation to stay happy and comfortable. I know I learned a lot about feet at this seminar, but Dr. Lacher and the entire Springhill Equine crew are happy to talk feet anytime! This is Tony saying may your food bowl be full and your litter box clean!!
Apr 13, 2015 | Feet, Hoof, Hoof Care, Lameness, Laminitis, Leg issues, Shoeing
This is Tony reporting from the Hoof Seminar on April 11, 2015. I am sure this will be a multi-part blog since I doubt I will be able to get all the information typed up without hitting the food bowl at least once so stay tuned if I stop mid-sentence. I will be back after refreshments….
Let’s start with the very true saying: “No Hoof No Horse.” Much like “You can lead a horse to water but you can’t make them drink” this saying sticks around because it is so true. Our horse’s take off, land, turn, and stand on their feet. And it’s a pretty tiny foot on the end of a long stick so little changes make huge differences!
A bit of anatomy will help us all get our bearings for some good discussion later. The lower leg is made up of the cannon bone, sesamoids, long pastern, short pastern, navicular bone, and coffin bone. The most important thing to remember here is that we are manipulating the hoof since that’s the part we can change but it has to align with all those bone and tendons and ligaments above.
Moving on to alignment. Tires on your car have to be aligned a certain way so they wear evenly. Hooves aren’t much different. By following certain guidelines the hoof will fly through the air, land, and take off again in perfect alignment with the rest of the limb above, the other three legs, and the big body it’s moving along. Think about it: a horse trotting creates 1,500 pounds of pressure and that’s at the trot! It’s really important to get alignment right.
OK starting with the view from side…….A line drawn down the front of the hoof should lay against the entire hoof wall and front of pastern. A line drawn down from the center of the fetlock joint should lay against the heel bulbs. In a perfect world the fetlock and hoof wall line would intersect at the middle of the fetlock joint but that is where the word guideline comes in.
Now pick up your horse’s foot. When it is freshly trimmed the heels should be at the widest point of the frog. This is really, really, really important. Many of us where taught that heel should never be taken off. Like many things we heard in our youth, things changed. The heels must be at the widest point of the frog. Next draw a line across the widest part of the foot and a line at the toe. Half the foot should be in front of the widest point and half behind.
Draw a line down the center of the foot long ways and half the foot should be to the outside, half to the inside.
Set the foot back down and look at it from the front. A line drawn down the center of the hoof should divide the hoof in half with 50% to the inside, 50% to the outside.
Hold your horse’s hoof up and let it hang from your hand. Draw a line down the center of the heels and again this should divide the hoof in half. This line should also be perpendicular to a line drawn across the heels where they will meet the ground. I hope you are noticing a pattern here. The foot should be symmetrical!
Notice none of this involved touching the sole with a hoof knife! By allowing our horses to form all the sole they want we help them keep good cushion beneath their coffin bone! Horses will naturally wear off any sole they don’t need so we don’t have to do that for them.
All this work has set us up for a discussion about the perfect break over, which is our real goal but you will have to wait until next week since I hear the full food bowl and clean litter box calling. Stay tuned. I will finish writing soon!
