Eye Problems Part 1

Eye Problems Part 1

Tuesdays with Tony

“Granny, what big eyes you have!”

“All the better to see you with, my dear!”

This doesn’t just apply to wolves and Little Red Riding Hood. Typical of prey animals, horses have giant doe eyes that sit toward the side of their heads and protrude out into the environment. Along with nearly wrap-around vision, having wideset eyes makes horses more prone to eye injuries. As you all know, eye injuries are always an emergency, and you should always call your veterinarian at the first sign of an eye problem.

Springhill Equine Veterinary Clinic

Given the importance of eyes and the numerous illness and injuries that can affect the eye, this will be a two-part blog. This week we’ll discuss Uveitis and Ulcers, and you’ll have to tune in next week to see what we’ll talk about then. That’s me building antici-purr-tion. And that’s a cat joke.

Uveitis

Equine Recurrent Uveitis, otherwise known as ERU, is a disease of the eye that can affect any horse of any age, breed, or gender. That being said, there are certain breeds that are more prone to ERU, like Appaloosas. Let’s break down each word of Equine Recurrent Uveitis. Equine, that one is simple, equine means horse. Recurrent, means occurring often or repeatedly. Finally, Uveitis, that one is a little more complicated. Uveitis basically means inflammation of the eye. More specifically, it’s inflammation of the layer of the eye that lies between the retina and the sclera and cornea which includes that iris, ciliary body and choroid. So ERU is inflammation of a horse’s eye that occurs frequently.

Signs of ERU are often very subtle. They can range from mild, clear discharge from the eye to thick mucoid discharge. There may also be occasional swelling of the conjunctiva and eyelids. More obvious symptoms can range from cloudiness of the eye to squinting. As you can imagine, with chronic inflammation come other underlying problems. Frequent inflammation results in the development of scar tissue which can affect the lens of the eye leading to cataract development and blindness. Similarly, uveitis can result in decreased drainage of the fluid within the eye which can cause an increase in ocular pressure. As the pressure increases, glaucoma develops and blindness occurs, and you can imagine the headache your poor horse must have. This stuff is painful!

Prevention and treatment of uveitis flare-ups are key. Unfortunately, there is no cure for ERU and long-term prognosis is guarded. Prevention is difficult but keeping your horse in a UV-resistant fly mask is your best tool. Catching symptoms early can help reduce the effects and control the pain. Systemic anti-inflammatories including bute and banamine can help during a flare up. However, topical application medications including steroids such as dexamethasone, topical atropine and/or topical non-steroidal anti-inflammatories including diclofenac reduce inflammation and minimize damage. Surgical implantation of a cyclosporine implant slowly releases the immunosuppressant for up to 3 years and reduces the occurrence and severity of ERU.

As I mentioned earlier, end-stage uveitis can result in cataracts and glaucoma, ultimately causing blindness. It can also result in shrinkage of the eye to the point of complete loss of the eye. Treatment of an end-stage uveitic eye is a salvage procedure and includes injection of medications including the antibiotic gentamicin or the steroid triamcinolone into the globe. The result of such injections kills the eye, causes complete blindness but also reduces the pain associated with ERU. Alternatively, a severely uveitic eye may be a candidate for enucleation where the globe is surgically removed. Either way, the ultimate goal for end-stage uveitis is to alleviate all pain associated with the eye.

Ulcers

Corneal Ulcers are a frequent occurrence in horses. I swear, they must find any bush or tree or shrub and intentionally stick their head directly in it with their eyes wide open. Horses really aren’t the smartest creatures on the planet. The smallest piece of sand or tiny little branch can wreak havoc on horse’s eyes, and a small abrasion on the eye can result in a defect of the cornea and a corneal ulcer. Corneal ulcers can range from superficial to deep and even can risk perforating the eye completely. A perforated eye can be disastrous for both horse and owner.

Springhill Equine Veterinary Clinic

Corneal ulcers can present similarly to uveitis. You may notice tearing, swelling, and squinting. If you ever notice any of these signs, it is your cue to call your veterinarian. Do not pass go, do not collect $200, just call your vet. An ulcer that is treated quickly and effectively can heal within days. Left untreated, a corneal ulcer can become a melting ulcer, or worse, can perforate the eye within days. Once diagnosed with an ulcer, your veterinarian will prescribe a very specific treatment regime that can range from 2-3 times a day medications to every 2 hours medications, depending on the severity of the ulcer. Trust me, they do not prescribe every 2 hours medications just for fun. They know exactly how much effort it takes but they also know that if you follow their instructions, it is very likely that the ulcer will heal and your horse will have a functional, seeing eye.

Occasionally, treatment may require the insertion of a subpalpebral lavage. A subpalpebral lavage, or SPL, is a system made up of tubing that is placed through your horse’s upper or lower eyelid and held in place by a footplate that rests inside the eyelid along the conjunctiva. The tubing is then weaved through your horse’s mane and a catheter with an injection cap is secured to the end. This system allows for easy medication administration directly to the eye without having to manipulate the eye itself.  SPLs are reserved for severe cases which require frequent administration of numerous medications.

While corneal ulcers can be simple and resolve quickly, they can also cause major problems and lead to long-term dysfunction of the eye. I cannot stress this enough: if you think your horse has a problem with his eyes, call your veterinarian immediately

Stayed tuned for next week’s Part 2 on eyes.

Until then,

-Tony

P.S. If you can’t wait a week to learn more about eyes, head on over to the Podcast Page and scroll down through the Straight from the Horse Doctor’s Mouth library. There are several episodes on eyes, more than enough to tide you over for a week. There are nearly 100 episodes altogether so far, which is a lot of horse doctor knowledge. That’s nearly as valuable as cat knowledge. Nearly.

Antibiotic Resistance Refresh

Antibiotic Resistance Refresh

Tuesdays with Tony

When you’re the supervising feline of a veterinary clinic, you know the amazing lifesaving things that antibiotics can do. You also know what a CATastrophe it would be if we didn’t have them. Plenty of things make a cat grumpy, but few things ruffle my fur quite like misuse of antibiotics that might lead to antibiotic resistance!

Let me explain how antibiotic resistance works and how we can avoid it. Antibiotic resistance doesn’t mean that your horse’s body becomes resistant to antibiotics, it means that the bacteria no longer respond to the antibiotics designed to kill them. They ignore the antibiotic treatment and continue to grow and reproduce, making your horse’s infection worse. When the bacteria become resistant, the antibiotics don’t work anymore, and your vet is left with few options to treat your horse’s infection. Infections caused by resistant bacteria are difficult or even impossible to treat.

Anytime antibiotics are used, it can contribute to bacteria developing resistance. Usually, the benefits usually outweigh the risks when the antibiotics are used appropriately. But if used unnecessarily or incorrectly, it increases the chance of creating antibiotic resistance. These mistakes are really common, so be careful you aren’t making them. And this stuff applies not just to your pets’ antibiotics, but also for the ones your doctor prescribes for you. We need our antibiotics to keep working so my docs can keep saving lives!

Springhill Equine Veterinary Clinic

Mistake Number 1

One of the most common mistakes many horse owners make is not finishing the entire course of antibiotics that their horse is prescribed. Here’s how it often happens… your horse is prescribed an antibiotic by a veterinarian, and you give it very diligently for several days. Then, you start noticing that he is improving, and you think, GREAT, the antibiotic is working and my horse is cured. Here is where the mistakes begin. 

It is extremely common for owners to see their horse improving and decide to discontinue antibiotics before they have finished the full course. DO NOT do this! Antibiotics are prescribed for a specific length of time. During this time the bacteria are being killed, which is why your horse begins to improve.

What happens when you stop antibiotics early is that some of the bacteria have not died yet, but they have been exposed to the antibiotic. When you stop the antibiotic, they start to reproduce again and the next thing you know, your horse is showing signs of infection again. When you see the signs return, you might try to start the antibiotic again. But this time, your horse does not improve. You call one of my docs out and they recommend a culture and sensitivity test which shows that the bacteria are now resistant to the antibiotic that previously worked on your horse’s infection. 

By discontinuing antibiotics before the full course was administered, antibiotic-resistant bacteria or “superbugs” are formed, and now the superbugs are reproducing. The superbugs recognize the first antibiotic and laugh at it when you try it again, as they have developed superpowers to prevent the antibiotics from killing them. Now we have a superbug that needs an even stronger antibiotic. Hopefully, this time, you have learned your lesson and give the entire course of prescribed medication. But sometimes it takes you humans more than once to learn your lessons! So you repeat the above scenario with stronger antibiotics, and a super-superbug forms. It isn’t long before there are no antibiotics left that the bug is susceptible to, and now your horse has a resistant infection that cannot be treated. 

Mistake Number 2

Mistake number two may be even more common than mistake number one. Do you have old leftover antibiotics lying around your barn somewhere? I bet if I cat-scanned your farm I would find some!

Here’s how it goes… You notice your horse has an infection and think, well, I have some of that old antibiotic in the tack room, I’m sure that it would be fine to treat my horse with that and I’ll save a little money. Never administer an antibiotic to your horse willy nilly! Even if it was once prescribed for him. ALWAYS call my docs first. You might think you’re going to save money, but this sort of thing often causes expensive and difficult problems that could have been avoided.

Different types of infections are caused by different types of bacteria. The bacteria causing your horse’s lung infection may be a different species than the ones that infect a skin wound. The antibiotic that will treat one kind of infection may not touch another. If you choose the wrong antibiotic, it not only wastes time and lets the infection get worse but is a great way of causing antibiotic resistance. Chances are you don’t know the right dose for that antibiotic either. So DON’T use what you have laying around the tack room, and DON’T buy something random at Tractor Supply. Don’t even get me started on expired antibiotics!

Mistake Number 3

Yeah, I know that it would be easier if you could just dump the antibiotic tablets in your horse’s grain and he would eat them all up. You don’t like giving them directly in his mouth, and neither does he. But what usually happens is that the horse picks through his grain and doesn’t like the taste, so he only eats part of the antibiotic dose. The bacteria are not killed when they are under-dosed – that only makes them stronger and more likely to become resistant.

The best way to make sure he gets the whole dose is to syringe it directly into your horse’s mouth. My docs will show you how and teach you tricks to get it done. Many of the common antibiotics they use can be dissolved in a little water inside a big plastic syringe and given just like a dewormer. You can even add flavorings like molasses to sweeten the deal. But your horse must receive his ENTIRE dose to avoid problems. If you find that you really can’t administer the antibiotics that were prescribed, my docs will find you another way to treat your horse and avoid antibiotic resistance.

Mistake Number 4

Sometimes people call asking for antibiotics to treat their horse and yet my docs have never even seen the horse. Not only is this illegal for my docs, it’s also very dangerous for your horse. If my docs prescribe your horse an antibiotic for an ailment that they have not examined your horse for, they are risking their veterinary license. Not to mention you are putting your horse at risk for developing antibiotic resistance. 

A common misconception is that all infections are treated the same. This could not be further from the truth. Some bacteria thrive in an environment without oxygen, some thrive in an environment with oxygen, others have super strong cell walls that require stronger antibiotics, and others are more easily treated. Even further, some infections are a mixed bag of multiple different bacteria. The only way for one of my docs to have any idea of what kind of infection your horse has is for them to see your horse. And did you know that viruses NEVER require antibiotics? Giving antibiotics for a viral infection just wastes money and creates antibiotic resistance.

I never want to find out what it would be like to live in a world without antibiotics, and neither should you. A lot of these problems we’ve talked about are avoidable simply by making sure you have a veterinarian examine your horse prior to treatment, following your vet’s orders, and calling them if you are having trouble with the prescribed treatment. The future of equine healthcare, cat healthcare, people healthcare, and every other kind of healthcare depends on it!

Until next week,

~Tony

P.S. Have you been to my YouTube Channel lately? I’ve got hours and hours of free horse knowledge waiting for you there. It’s way more beneficial than bingeing on Netflix, and easier to share with your friends: win-win!

New Deworming Study Conclusions

New Deworming Study Conclusions

Tuesdays with Tony

As a regular reader of my weekly words of wisdom, I’m sure you’re aware of my strong feline feelings on deworming. However, I shall summarize it briefly. Deworm less. A lot less. Like, deworm-once-a-year less. This is accompanied by, do fecal egg counts to determine if any horse needs more deworming, and even then it’s only going to be a total of twice yearly. Where did all my purrfectly amazing feline knowledge come from? Science. The Gluck Center at University of Kentucky, and more specifically the hard work of a prodigious parasitologist, Dr. Martin Nielsen and the other humans who work in his lab. You may have seen a recent paper from his lab that looked at parasite egg shedding and numbers in an incredibly detailed way in a herd of horses who haven’t been dewormed in 40 years! This week, let’s talk about the work of Dr. Dr. Ashley E. Steuer. She’s the lead author on this paper. And no, I didn’t type Dr. twice on accident. She’s a DVM and a PhD! Also, cats don’t make mistakes.

What They Looked At

Gluck is a super cool place to geek out on horse scientific stuff. They’ve got research going on all sorts of things. As part of that research, they have a herd of horses maintained on pasture that never get dewormer, and hasn’t since 1979. 

For this paper, they asked the following questions: 

  1. Do horses shed more parasite eggs at different times of year? 
  2. Do young horses shed more than mature or aging horses? 
  3. What species do they shed when? 
  4. When do foals start shedding? 
  5. Do pregnant mares shed more eggs right before foaling? 

If you want to read the entire paper, which I recommend, you can click here. For the rest of you, I’ll give you my synopsis below.

Seasonality

Some work has been done on the question, do horses have a season to their egg shedding? Apparently that work was mostly done long ago in a land far, far away (England). This work was done in a very different climate: Kentucky. The horses were monitored for a full twelve months, and Kentucky, being Kentucky, was kind enough to have four seasons. (My native land of Florida only has Summer, and a brief not summer, then back to Summer.) This allowed for evaluation in a truly hot season, and a for-real cold season, with nice middle of the road seasons as well. Drum roll please: no real difference was seen in the adults based on time of year. This is different from what the British studies found, and may be a reflection of different types of climates or a change in parasites. Well, that’s interesting!

Springhill Equine Veterinary Clinic

Young Horses and their Shedding

Boys are ickier than girls. That was my fine feline conclusion. Foals shed a combination of Parascaris, and Strongylid sp. Young foals shed predominantly S. westeri as expected and boys do it earlier and more; girls are less and longer. Boys were just plain higher than girls on the other two. There was a hypothesis put forward that it may be because colts eat more poop than fillies. Think about that the next time one of them wants to give you a cute little baby kiss. Foals start shedding eggs pretty quickly, and peak at around 6-8 months of age. Foals were also susceptible to Anoplocephala sp (tapeworms), but it seems to take them 4-6 months to even get them. I felt like foals just like to spread their parasites around. It does make sense since their immune systems aren’t quite fully on-line yet, but jeesh, do they have to go contaminating everything? 

What About Pregnant Mares?

There’s work in cows and sheep to show an increase in parasite egg shedding around the time of calving and lambing. Based on the work on these horses, that doesn’t seem to hold true for horses. The very smart human (I mean, she is a Dr. Dr.) did caution this was a small group of horses. I say this is even more reason to do a fecal egg count before deworming! Why spend the money, and the time, and the aggravation deworming your mama mare if you don’t have to? Science says see if she’s even shedding parasites at all.

Springhill Equine Veterinary Clinic

Cat Conclusions

What’s this all mean? Never deworm again? That can’t be true. Tony, you’ve gone crazy, you say. This is a study that looked at a very specific herd of horses and asked a very specific question about shedding of parasites. This study didn’t discuss the risk level of the parasite load in the horses in the study. It does give us great insight into parasite egg shedding patterns when there is no influence of dewormers. For this wise cat, it also makes me an even stronger believer in fecal egg counts before deworming any more than once yearly. 

P.S. My Docs recommend once yearly because it minimizes the risk of a deadly type of colic caused by Strongylus vulgaris (large strongyles), and the less deadly, more annoying gas colics that Anoplocephala sp (tapeworms) cause. This study did not look at risk factors for complications when not deworming for 40 years, it simply looked at what worms were there and how many of them. In general though, it seems horses tolerate their parasites fairly well so don’t deworm them every month!! 

P.P.S. My Docs are excellent at helping you formulate a parasite plan for your property, and your horse’s lifestyle. Don’t go all willy nilly. The drugs available now all have resistance. With a little bit of planning, you can help them last as long as possible. Give my minions a call at (352) 472-1620. 

Until next week,

~Tony

Urban Legends of the Horse World

Urban Legends of the Horse World

Tuesdays with Tony

Let’s talk about some of my favorite topics that help horse owners spend money needlessly. I like to call these the Urban Legends of the Horse World. Some have a bit of fact, and I emphasize, a bit, behind them. Some are wild tales meant to scare children around campfires at night. Either way, I watch a lot of horse people spend a lot of money or time on them for no good reason. Don’t worry, Tony’s here to help you out.

Colics and Walking

I’m starting with this one since it’s one of my life’s missions to get humans to stop walking colicky horses! If your horse lays down to roll, it will NOT cause their intestines to twist. In fact, it’s the other way around. Horses become intensely painful and roll because their intestines twisted. I know you’ve heard this one from me before, and I’m saying it again. Do.Not.Walk.Your.Colic! Okay, I’m ambling down from my soapbox now.

Hindgut Ulcers

I’m prepared to face the wrath of the internet on this one. Hindgut ulcers in the way you are thinking of them aren’t a thing. Yes, my Docs see hindgut ulcers, but it’s rare and is ALWAYS secondary to massive doses of NSAIDs like bute. For the most part these drugs are safe, but if given in too high a dose for too long, they quite literally destroy the hindgut. For some horses, this is one dose at a high level, for some it’s 4-5 days of high dosing, and for some it’s weeks of overdosing. These drugs are easy to use all willy nilly, but it’s important to check in with my Docs about best practices. Horses with hindgut ulcers are incredibly sick, and it can be life-threatening. They don’t experience a vague sense of unease, or balk at your leg, or pick up the canter incorrectly. They try to die. 

Okay, now for the tiny kernel of truth behind hindgut ulcers. The more all the amazing gut researchers out there learn about the critters that live in the GI tract, the more they know they don’t know. I think they should ask a cat. We know everything. Just ask us! Anyway, what is very clearly known is that the bacteria, viruses, fungi, and protozoa that live in there are all important, and are all delicate little flowers. Any little thing upsets them. There are a million solutions proposed for managing this upset. There are two that have science behind them: forage and Saccharomyces boulardii. That’s it. Not hindgut buffers, not magical hindgut happiness potion, not vaguely labeled hindgut supporters. Hay and maybe some yeast. Mostly hay. Want to keep your horse’s hindgut happier? Feed them more hay! 

Springhill Equine Veterinary Clinic

Stomach Ulcers

What? Are you crazy, Tony? Are you saying stomach ulcers aren’t a thing?? No. I’m not actually saying that. I am saying that a bajillion of the things out there that say they will fix it, won’t. Stomach buffers will help the symptoms temporarily, but not long term. Many of the wonder cures out there are buffers. Treatment is aimed at first knowing what kind of ulcers you’ve got: squamous or glandular, then targeting treatment to the type, then modifying life and diet to avoid recurrence. Wonder cures which involve two pumps or scoops or packets of something random do not factor in here. 

Joint Supplements. Okay, Supplements in General.

Let’s evaluate the size of a horse. I’m going to be kind and say the average horse weighs 1100 pounds. Yeah, that’s right, I’m saying most of you humans have overweight horses. Let’s look at the average supplement: 2 ounces. That’s the size of the scoop. That’s 0.00002 pounds per pound of horse body weight. Chances are good that supplement isn’t doing much. For example, when my Docs recommend flax seed for itchy skin, they recommend 1 POUND per day minimum. Think about what is in your supplement, and then the quantity you are feeding before expecting it to do a lot. The other thing about supplements is that they are the wild, wild west of the nutrition world. This is true for human supplements, too. Pretty much as long as you don’t say your supplement treats a medical condition, you can say it. My Docs can help you evaluate supplement choices, but know the answer will be just don’t do it 95% of the time. 

There are a whole lot of urban legends out there in the horse world. For 99.999999% of the horses in the world the right answer is a good diet based on 1-2% of their bodyweight as roughage, only enough concentrate to supplement vitamins, minerals, and protein to support workload, clean water, and turnout and/or exercise to keep the body moving. The rest of it separates your money from your wallet. Horses do that well enough already! Talk to my Docs for help sorting out the urban legends from the truth. 

Until next week,

Tony

P.S. If you are thirsty for knowledge on the things I talked about here, you should go listen to the podcast my humans do. They have a whole lot more to say about this stuff than I do. To be fair, I’m limited to 1,000 words, and they can talk for 30 minutes to an hour. I’m not staying awake that long unless I’m blocking traffic in the Clinic parking lot. Anyway, you can find all 90+ episodes of Straight from the Horse Doctor’s Mouth by clicking here, or subscribing wherever you get your podcasts. You’ll thank me later.

Equine Podiatry

Equine Podiatry

Tuesdays with Tony

It was so wonderful to see everyone at our seminar Thursday night! I haven’t been feeling like myself lately. Seeing all of your smiling faces really lifted my mood and made me feel much better. It’s been so long since we’ve been able to have in-person events, and I’m excited that we are starting up monthly seminars again.

This week I want to recap Thursday’s seminar topic, Equine Podiatry, just in case you missed anything. I consider myself one extremely lucky cat to be in the presence of such incredible doctors every day. Dr. Staples is no exception; she has been a wonderful addition to the Springhill Team and her knowledge of all things horse feet far exceeds that of mine, which is saying a lot. Dr. Staples is an Equine Podiatrist (which means she’s both a Veterinarian and a Certified Journeyman Farrier), and Thursday night’s seminar was an introduction to all things equine podiatry. We discussed everything from anatomy and conformation to common issues and diseases.

Springhill Equine Veterinary Clinic

You all know the saying, “no hoof, no horse,” and there is no truer saying. The number of soundness problems my docs see that start from hoof problems is tenfold. Conformation plays a huge role in how the anatomy of your horse’s hoof is affected. No horse has the perfect conformation or the perfect feet, but what you do with the imperfections can pave the way for your horse’s comfort and soundness.

A normal hoof will have a straight hoof-pastern axis. It will also have even wall height medially and laterally with a frog centrally set that hits the ground evenly and lightly. When a horse has a normal hoof, they are more capable of withstanding the pressures applied to the foot and leg with movement. A normal hoof will have a 3-5 degree positive palmar/plantar angle which allows the horse to move his feet in ways that the digital cushion can support and that the tendons and ligaments are not overly strained.

Sloping hooves have a broken back hoof-pastern angle often because the horse has a long pastern. These horses are your flat-footed horses. Their frogs often hit the ground with more force and absorb more of the concussive forces. Horses with flat feet lose a large portion of their squishy digital cushion, they are prone to long toes and underrun heels. This also makes them more susceptible to have a negative palmar/plantar angle of their coffin bone. The more negative the palmar/plantar angle, the more tension is placed on the tendons and ligaments which can lead to tears and injury.

Upright hooves result in a broken forward hoof-pastern angle, which gives the appearance of a club-like foot. It doesn’t necessarily mean the horse if club footed, it means the hoof is extremely vertical, the frog rarely hits the ground, and the toe of the sole ends up taking on most of the concussive forces when the horse moves. These horses are often foot sore at the toe because as the horse moves, it’s basically stubbing his toe with every step. An upright foot also put undue stress on a horse’s tendons and ligaments which can lead to soundness problems, including tears. Cats are made perfectly and never have issues with conformation or anatomy, so learning about how a small change in structure can result in catastrophic problems for a horse really made me appreciate 1) cats, and 2) our farriers for keeping these horse feet in working order.

Springhill Equine Veterinary Clinic

Dr. Staples talked a bit about different diseases that can affect the hoof, and how conformation can cause abnormal forces, which can lead to disease, and how disease can lead to the hoof structure becoming abnormally shaped. Systemic diseases such as sepsis or endocrine diseases (including Cushings) can lead to hoof problems.

Laminitis is a disease of the hoof that plagues horse owners. It is the 9-letter word of the horse world and is one word horse owners never want to hear. Systemic disease increases a horse’s likelihood of developing laminitis. Laminitis occurs when the Velcro (lamina) that holds together the hoof wall and the coffin bone became inflamed and starts to separate. Separation of the lamina allows for downward rotation and/or sinking of the coffin bone within the hoof capsule. Similarly, disease of the hoof such as white line disease can lead to the separation of the lamina and result in laminitis if it’s not treated quickly and effectively. Yet another cause of laminitis is injury to a limb resulting in inflammation of the opposite limb because the horse is putting most of his weight on the limb opposite the injury.

Not everything that affects the hoof results in laminitis. Conformation can affect how a horse’s hoof grows which can result in abnormal forces on the hooves. Conformation can be addressed by your farrier and changes in shoeing can be used to help compensate for the abnormal forces caused by poor conformation. Poor trimming/shoeing can also cause abnormal forces. Toes that are left too long or toes that are trimmed too short can cause soundness problems and put undue stress on your horse’s limbs. A good working relationship between your veterinarian and farrier is essential to correcting trimming/shoeing problems.

The number of problems that can affect feet is innumerable. Nothing is more frustrating for an owner than an abscess. Chronic abscesses are even more frustrating. The shape of a horse’s hoof can make them more prone to abscesses, the environment can be the cause of abscess, and irregularities such as tumors within the hoof capsule can lead to abscesses.  Flat-footed horses with long toes tend to develop abscess more frequently than horses with a normal hoof. Florida is a hotspot for hoof abscesses in horses. It’s wet 90% of the year. Horses are bred to be in drier environments. The constant wetness in Florida keeps horse’s hooves moist, and opens up micro holes in the foot that allows bacteria to seep in resulting in an abscess. If your horse is one of those horses who has repeat abscesses, I highly advise you to get your veterinarian involved. There could be a much deeper issue that requires veterinary intervention.

Occasionally hoses can develop benign tumors in their hoof which causes pressure points on the coffin bone resulting in bone loss and recurrent abscesses. These tumors are called keratomas. They can result in lameness, but they can also be present without issue. The only way to diagnose a keratoma is with radiographs. This is where your veterinarian can provide insight to the inside workings of your horse’s hooves.

Springhill Equine Veterinary Clinic

This leads me to my next soap box: An ounce of prevention is worth a pound of cure. And this is where you all have to play your part. Be involved, be aware and know when you need to seek help. You know your horse better than anyone else which means you know when something is off. Your vet and farrier know your horse pretty well too, and having them involved in wellness care for your horse can prevent hoof problems and identify them early should they arise.

Routine blood work to screen for Cushings and routine radiographs that are shared with your farrier can help identify problems early on and help to resolve the complication before it becomes a major, potentially life-threatening issue. Communication between your veterinarian and farrier about your horse’s overall health and hooves can result in the prevention of disease and hoof worries. Therefore, take it from this old cat, have your horse’s feet attended to by your farrier every 4 to 8 weeks (depending on your farrier’s recommendations), continue wellness prevention with your veterinarian every 6 months, and don’t be afraid to call your veterinarian if you believe there is any change to your horse. I promise you, it will save you a lot of money, a lot of heart ache and potentially your horse’s life.

Until next week,

The Basics of Horse Health

The Basics of Horse Health

Tuesdays with Tony

It’s January, which means two things: it’s cold, which I hate, and Springhill Equine Wellness Program sign-ups, which I love, are in full swing. Let’s talk about the cold first. I have asked my humans repeatedly to make the temperature outside more to my liking. Their only offer to solve this problem is a horrible plaid jacket they attempt to make me wear. This is a completely unacceptable solution. Thus I sit at the front door and demand the repeated opening and closing of the door so that I may move inside or out depending on my minute-by-minute temperature desires. I feel it’s a solid plan. The humans seem to object, but I ignore them. On to the thing you probably care more about: the Wellness Program, in other words, your horse’s basic healthcare needs. What are they, and why do my Docs do what they do?

The Exam

Every horse should get a good basic exam every time they get a vaccine. This isn’t a fancy exam. It’s a heart, lungs, gut sounds, my Doc looking your horse over exam. It’s tempting to wonder what the heck they’re doing during this quick exam, and how much information they can gather. The answer is a lot. Giving a highly trained professional 5 minutes to look over your horse, take a listen, and talk to you about what you and your horse are up to will get you more information than all the hours you can put in with The Google Machine. 

During that time my Docs are assessing your horse’s heart rate and beat. Is it regular? Is the rate appropriate for the fitness level your horse should be at? They are listening for early signs of asthma, a ridiculously common Florida horse problem. Gut sounds tell them if there is a hint of sand, or too much gas, or maybe some impending diarrhea. All the while they are looking at all your horse’s other body parts. You may not realize it because my Docs are slick like this, but they’re evaluating feet, muscles, topline, haircoat, eyes, and a million other things in that 5 minutes, all while integrating the information you’re giving them about your horse’s eating, drinking, and exercise habits. I dare you to get all that from the Faceplace!

Vaccines

Serious Tony here. Encephalitis is EVERYWHERE in Florida, and Rabies is really bad. Vaccines are important! Every single horse in the United States should have Eastern and Western Encephalitis, Tetanus, West Nile Virus, and Rabies vaccines yearly. If you live in the swampy, mosquito-infested land of Florida, the encephalitis and West Nile vaccines should be given at least every 6 months. Do you know what happens when you guys try to keep track of this yourselves? It doesn’t happen every 6 months. Often it doesn’t even happen every year. These diseases are deadly, and heartbreaking. Eastern encephalitis carries a 95% mortality rate. West Nile horses rarely return to their previous level of competition. 

Springhill Equine Veterinary Clinic

If your horse is around other horses, they should also be vaccinated for rhinopneumonitis and influenza. These are the respiratory viruses of the horse world. Horses get them from other horses. That means it’s not just for show horses. If you trail ride around other horses a lot, your horse should get these vaccines. 

There are other vaccines out there, like Strangles and Potomac Horse Fever. Some horses need these. Some don’t. The best person to determine this is your veterinarian. Not a random person you met at the feed store, not your farrier, trainer, or Facebook friend. TikTok should also not be a guide here. If they aren’t a vet, they don’t decide. That’s some Tony wisdom right there.

Know how to best ensure your horse gets the vaccines they should, when they should? Sign up for Springhill Equine’s Wellness Program. So easy, even a dog can do it. Trust me. You humans can’t keep track of this without some feline help!

Coggins

I’ve got entire blogs on why one should have a Coggins test, and how it’s spread. All the info you need on this. This week I’m here to say once again: sign up for our Wellness program so you’ve got your Coggins when you need it. “Emergency” Coggins really shouldn’t be a thing. If you think you might take your horse off property, get a Coggins on them when my Docs are there doing vaccines. It makes life much easier when you suddenly decide to take Flicka for a trail ride on Saturday, but realize on Thursday evening you don’t have a Coggins.

Dentals

Big old Tony soapbox here. Dental care should be performed by your veterinarian. Just this past week we saw a horse who had their dental care performed LAST WEEK by a lay dental floater who had missed a giant tumor on the jaw. I know. I know. That’s not how my random person with an internet certificate in dentistry works. But it is how they work. Your horse’s mouth should be evaluated at least yearly by a veterinarian. That means sedation, a speculum, and a bright light. That means a veterinarian. Sedation can only be legally administered by a veterinarian. 

You can tell this is a pain point for this cat. It’s because my poor Docs have to handle the repercussions of bad dental care. Often this means a horse not eating for days to weeks after a dental float, serious health problems from bad sedation choices, and missed issues often in the back of the mouth. Not to mention, you are out money for a service that was performed badly. 

Okay, I know that was a lot, but it’s enough to get my hackles up. Also, good, consistent dental care is the single greatest thing you can do for your horse to help them have a happy, long life eating normal food. As those teeth decline, feeding becomes a huge challenge. Take care of them early and often, and you will save a ton of money on feed over the lifetime of your horse. This doesn’t even include the benefit of improved communication while you’re riding them.

Deworming

Last but not least in the basics of horse healthcare is deworming. By this I do not mean place a deworming product in your horse’s mouth every month, six weeks, at the farrier visit, based on the lunar calendar, or some other crazy horse-person archaic deworming schedule. That’s right, I’m talking about you, horse people. Proper parasite management involves knowing fecal egg counts. This allows targeted deworming of the horse’s dropping the most parasites around their world, and NO one else. 

Let me also state right here that just because one horse is high doesn’t mean all the other horses on a property are. This is so 1990’s thinking. Be hip and modern. Use fecal egg counts to guide deworming. For Florida, this means check fecal egg counts once yearly generally during what counts as our Winter, Spring, or early Summer. Only horses with high egg counts are dewormed. In the late Fall, everyone gets dewormed with an ivermectin/praziquantel product. My Docs recommend Equimax for a variety of reasons. That’s it. See, I just saved you money, time, and argument with your horse over taking their dewormer. 

Know how to get all this stuff for your horse, save time and money, and have my awesome group of humans keep track of all of it for you? Sign up for our Wellness Program. Time is running out to get in on the plans. Signing up is easy. Just go here: https://springhillequine.com/wellness-sign-up-sheet/ and do the things. Now go back to perusing the internet for the thing it does best: cat videos!

Until next week,

~Tony
