Managing hoof abscesses in horses: a step-by-step guide

Sun, 01 Feb 2026 16:54:36 GMT

What is an abscess?

A horse hoof abscess is a localized bacterial infection trapped inside the hoof capsule, causing intense pressure, heat, and sudden, severe lameness (though not always – I’ve had many abscess without taking a lame step). They can occur when bacteria enter via hoof cracks, injuries, or the white line, often during wet, muddy conditions. Other factors can be extreme ground changes, for instance after getting a significant amount of rain after a dry spell, or vice versa, as hard ground can cause bruising. Another common event in winter is when mud freezes and creates very hard, rigid ground to make for bruising on thin soled horses. Poor hoof balance can also be a trigger, as imbalances can create corns and pressure points.

**If you have a thin-soled horse, it’s a great supportive/preventative tactic to boot them for turnout when the ground is extremely hard or when mud freezes.

If your horse is lame, the first step is to notify your veterinarian. Once an abscess is confirmed or if your veterinarian recommends treating it as such, here is a step-by-step protocol on management. Radiographs are always appreciated to see the extent of the infectious tract or where it might possible release.

1. Identification and Diagnosis (done by veterinarian in the field)

Clinical Signs: Sudden onset of severe lameness, increased digital pulse, heat in the hoof, sensitivity to hoof testers, and possible swelling of the limb or coronary band.
Physical Examination: Clean the hoof thoroughly. Use hoof testers to localize sensitivity. You can also palpate around the foot to feel for areas of concentrated heat or soft spots. The soft spot is likely where the abscess will release. Typically the horse will not be able to weight the infected foot, so picking up the opposing limb is very hard for them.
***Remember, abscesses can “swim around” in the capsule.
A common presentation is pointing of the toe, shown below:

2. Soaks: For help on Epsom salt soaks, watch this video to see the process in action .

· Epsom salt soaks are recommended to draw out the infection.

· Supplies: soaking boot or soft feed pan, Epsom salts, hoof pick, warm water

· Process: mix 1 cup of salt per gallon of warm water in a sturdy rubber pan or soaking boot, ensuring the water covers the coronary band. Soak for 15–30 minutes, 1–2 times daily.

3. Wrapping:

· After soaking, recommend keeping infected foot in a boot. This can be done in two ways.

IF YOU HAVE RIDING BOOTS OR CLOUD BOOTS:

· Simply wrap the foot in a diaper, orienting the “baby butt” part over the heel and securing in the front of the limb. Size 1 diapers fit most feet.

· Optional additions: Lather sole (if that’s where the soft spot is) with green Epsom poultice or animalintex pad. I prefer the pads to the Epsom poultice, as the Epsom poultice can cover up the ability to see or smell the drainage.

· Baby powder the boot and put it on over the diaper. Be sure that boots are worn on BOTH fronts (balance and comfort for the opposing limb).

· The diaper will allow you to assess drainage and infectious smell.

If you DO NOT have a riding boot or cloud boots:

· You will need to wrap the hoof in a duct tape bootie.

· For help with wrapping, watch this video for guidance

***WRAPS AND BOOTS TO BE CHANGED DAILY FOR SOAKING AND ASSESSMENT

4. Abscess Drainage

· Once drainage is identified on the diaper, please text me a picture of your finding. The drainage will present as puss, often yellow and will smell putrid. Search around the hoof capsule to identify the abscess tract, and please send me a photo of that, as well.

o If on the coronary band, you will feel a horizontal slit just below/at the hairline. If it is a bar abscess, often there will also be an additional tract found at the heel(s). If there is a tract at the toe, often there will be another tract just opposing it at the top of the hairline. These are not rules, just common patterns.

· My personal rule is if it takes more than 7 days for the abscess to drain (considering you’ve already spoken with your veterinarian at onset), please communicate with them that there is a lag time in drainage. Additional measures may be appropriate.

5. Soaking regimen after rupture:

Recommend switching soaking solution to an antiseptic product.
CleanIt Hoof Soak Solution is my personal favorite.
To make the product last, use half of the powder in half a gallon of warm water. Store the rest of the bottle in the refrigerator. This solution is good for 24 hours. Soaking back-to-back is advisable.
For the “fuming phase” (see label) I recommend just taking a grocery bag or a Ziploc bag and putting over the foot, secured with a little duct tape.
This process is time consuming, best to park your horse in front of hay net or a meal for entertainment.
Vetericyn Hoof Soak is also great. Can be purchased at Tractor Supply Co, or amazon

o ***Please follow directions on product labels for them to work as intended.

Frequency of soaks after rupture: pending on the size of the abscess, I recommend alternating between Epsom salt soaks (to continue drawing out the infection) and antiseptic soaks. Typically, this only takes a few days. Continue to send me photos of drainage.
Example: can do two days of CleanIt and then the third day do Epsom salts again if still draining. If drainage stops after second CleanIt soak, no further soaks needed.
Continue with booting with diaper or making bootie during this process.
Pain level and heat in hoof should decrease as drainage continues. If not, please notify your vet immediately.

6. Pain Management and Supportive Care

· Speak with your vet about candidacy for NSAID (such as bute) to help with pain management

· Remember that inflammation will help to push out the abscess. The more they can move, the quicker it will rupture.

· Keep the horse in a clean, dry environment to prevent further contamination.

· Heavily bed stall for comfort. If you do have cloud boots, booting both feet will help protect the opposing limb, as it is working double time.

· No forced exercise at this time.

· **Body work is contraindicated during this time, as it can destabilize the body’s coping postures. Bodywork AFTER the abscess has ruptured and healed a bit is encouraged.

7. Aftercare

· Once drainage ceases and the horse is comfortable, discontinue aforementioned protocols.

· If the abscess involved the sole, it may be appropriate to boot for a few days to allow the foot to harden. Imagine you had a blister burst on the bottom of your foot and you’re walking on “fresh skin.” It may take a few days for it to toughen up, same with an abscess. Give them time and protection. Topicals typically aren’t necessary for this, just keeping their feet dry and clean. Though Artimud would be appropriate in some cases.

· If the abscess was at the hairline, it is recommended to keep that tract clean. Use a syringe to flush out the tract daily to keep it clean of debris. This flush can be done with water, diluted apple cider vinegar (50/50 water/AVC), or diluted chlorhexidine (2TBs chlorhexidine in one gallon water). You are welcome to pack the slit with Artimud to promote healing.

o Note: hairline abscesses will be visible on the capsule until they grow out completely. Abscesses on the sole tend to heal relatively quickly. Often they can create corium scaring, and you will see a blemish or deviation with how the sole grows/heals. This is not unlike getting an injury in your own nail bed and now your nail grows differently.

· Gradually return the horse to normal activity as advised by a veterinarian or farrier.

· Schedule a follow-up examination to ensure complete healing.

911 - When an abscess turns into an emergency:

· Again, it is crucial to keep your veterinarian updated through this process. It’s better for them to be aware.

· If the abscess does not rupture after 7-day soaking protocol to draw out infection, please notify your vet that it still has not ruptured. (Some vets may want to know sooner)

· If the horse develops fever, swelling in the distal limb that does not subside, or pain level rises.

· Hoof abscesses do have the potential to cause osteomyelitis, which is infection of the bone. This can be fatal and requires immediate veterinary attention. Often this is treated with regional limb perfusions (antibiotic administered directly into the distal limb), magot debridement therapy (safely removes necrotic tissue), and/or aggressive topical antibiotic treatment.

Chronic, recurrent abscessing:

Speak with your veterinarian about testing for PPID, as uncontrolled ACTH can contribute to chronic abscessing. These are typically on various feet.

Other possibilities that can contribute to chronic abscessing (esp. if on the same foot) would be a keratoma. A keratoma is a benign growth, or a disorganized collection of keratin, that imposes on the coffin bone. They can cause lameness and chronic abscessing. These are typically visible on the solar aspect of the hoof, as they tend to create a deviation of the sole into the whiteline. Your hoof care provider should be able to identify this, though a series of radiographs and veterinarian assessment are needed to confirm. Note: not all keratomas are problematic, I have many horses on my books that don’t experience issues from them. They’re typically not a problem until they’re a problem.

Understanding Negative Palmar/Plantar Angles and Caudal Failure in Horses

Tue, 05 Aug 2025 05:56:08 GMT

Caudal failure refers to a regression in the integrity, structure, and function of the back of the foot. Not always, but typically this is associated with low or negative palmar (front feet) or plantar (hind feet) angles. NPA = negative palmar/plantar angle. In my practice, I consider low angles zero to 2-3 degrees, while anything negative obviously is below zero degrees. Ideal palmar/plantar angles range from 4-8 degrees, but this depends on the horse. I have some horses who prefer to be on the lower end of this range, while others appreciate to be at the higher end.

Another factor to consider is the hoof pastern axis (HPA). The hoof-pastern axis (HPA) is an imaginary line that runs from the center of the pastern (the area below the fetlock) down through the hoof, when viewed from the side. It's a key indicator of hoof balance and alignment in horses. Ideally, this line should be straight and aligned with the dorsal (front) hoof wall, indicating proper weight distribution and minimizing stress on the limb. Deviations from this straight line, known as broken-back or broken-forward HPA, can lead to various lameness issues and strain on the musculoskeletal system

Ideal HPA:

When viewed from the side, the pastern and hoof should form a straight line that aligns with the dorsal hoof wall. (Figure A)

Broken-forward HPA:

This occurs when the hoof angle is more sloping than the pastern. It can be seen in club feet and puts excessive stress on the toe area. (Figure B)

Broken-back HPA:

This occurs when the hoof angle is more upright than the pastern, creating a break in the line. This often results from long toes and low heels, placing excessive strain on the back of the foot, including the navicular bone and deep digital flexor tendon. (Figure C)

Often times, low/negative angles or caudal failure can be associated with a few different presentations:

A steep downward sloping down hairline with matching downward sloping lines on the caudal aspect of the wall. This suggests that the internal structures are underdeveloped, weak, and essentially collapsed. You can often see the caudal foot “spilling out the back” over the heels. This is seen on Figure 1 at the start of the article.
Prolapse of the frog. This can be seen by the deep V of the hairline. Often if the frog does not have sufficient support and is suspended (not uncommonly seen in an open heel perimeter shoe), it can prolapse (or sag) and can be proud of the heels as it seeks stimulation/contact from the earth. It can be very uncomfortable coming out of this setup. I lean on cloud boots for a few weeks when rehabbing these soft tissues back to their rightful places.

What to do?

A balanced trim to mitigate angles as effectively as possible. If this is an extreme case, radiographs are always appreciated. Trimming is a subtractive process. At times, a prosthetic (AKA shoeing) is needed to ADD to the foot to achieve balance. This is commonly seen with low/negative angles if there is not enough foot to achieve balance, or appropriate angles, with just a trim.

Ensure appropriate frog support and stimulation. This can be achieved in a variety of ways: boots, shoes (with proper frog support) or bare (if appropriate). With appropriate input/stimulation to the frog, of course paired with a heel first landing, the soft tissues (including the digital cushion) will slowly regenerate and strengthen. This is physical therapy for the distal limb. At times, a wedge pad is appropriate to build additional depth and to achieve an improved palmar/plantar angle.

If a horse is transitioning out of a perimeter shoe without frog support, and there is frog prolapse, it is recommended to boot the horse for a few weeks. This is a gentle way to guide the soft tissue back to their appropriate places before going to shoes or remaining bare. Shoes with frog/solar support offer relatively consistent input – when a horse is booted, each flight phase of the step allows momentary relief of the solar support given from the boot. Meaning the pressure is released when their foot is in flight while walking or laying down – it’s not a constant input of pressure. This consistency of a shoe is great when the tissues are in their rightful places but can be a bit much if there is prolapse.

Facilitate heel first landings via a balanced trim and appropriate shoeing package or booting to rehab the caudal foot back to health.

Consider appropriate dietary changes to better feed the hoof. Hoof quality is made in the feed room. Consider testing your hay and determining which minerals your horse may be low in. Keep an especially close eye on copper and zinc. (to be discussed in a future article)

MOVEMENT: turnout. Forage, friends, and freedom. Physical therapy is movement and movement is physical therapy.

Sit back and watch their caudal foot blossom. It does take time, but it does heal. Be patient and trust the process.

Don’t wait for the cascade of issues to amplify. Caudal failure can be rehabilitated with proper interventions. Your horse will thank you .

Poor landing. The foot is designed to land heel first. An underdeveloped caudal foot is not comfortable to land on, so they tend to land toe first. Toe first landings undermine the integrity of the caudal foot and can cause an atrophy and waning of soft tissue health, which perpetuates the pathology. This includes the frog, so watch for a thinning frog or disease (thrush). Thrush is an infection - it can hurt. If it hurts, they won’t land on it… again cue cascade of issues. (Check out The Red Mare Project podcast Episode 3 Heal Pain Heartache on Apple Podcast or Spotify)

Issues highly correlated with low/negative palmar/plantar angles:

*Please note that this is not an exhaustive list. Furthermore, each case is unique so it’s hard to determine if NPA caused the body issues or if it was the inverse – it is best practice to address all pathologies with the horse’s care team to give the horse the best chance of rehabilitation.

Pathological posture: Splayed out or camped out/under. A horse camped under is much more common. This is often referred to as “goat on a rock”. A horse camped out may be experiencing a more acute situation (laminitis) or navicular issues. Both are affiliated with a whole slew of issues (this will be discussed in another article).

Extremely thin or weak digital cushion. The back of the foot should be robust and voluminous. On a good footed horse you may have heard me call it a “Big Mac foot”, just a full digital cushion. The digital cushion is the foot’s shock absorber. Weak digital cushion = poor shock absorption, which means other structures are taking the brunt. Cue the cascade of distal limb and body issues.

Back pain, particularly in the lower back
Muscle tension
Neck and poll pain
Excess torque on distal limb soft tissue, thus making them more vulnerable to injury.
Note: Rarely do soft tissue injuries in the limb happen suddenly. It’s 1000 unbalanced steps that compound until there is failure.
Behavior changes: reluctance to go forward, inability to fully/properly engage, bracing of the neck and/or back, bolting, you name it. It depends on the secondary effects (those just listed above) from the NPA.
GI distress/ulcers from pain/stress.
Dental changes due to the change of flight pattern from poor balance. The feet and teeth are highly innervated. Dental and footwear pattern often mimic each other quite closely. (this will be discussed in another article)

Understanding NPA and Caudal Failure

The Danger of Thrush Infections in Horses

Sat, 25 Jan 2025 08:03:51 GMT

Thrush is an anaerobic bacterial infection that can cause an array of issues. Often the frog is the primary victim, though the central sulcus can be a forgotten area of attack. The central sulcus is the top/center of the widest part of the frog (at the back of the foot). Central sulcus thrush can create a “butt crack” appearance. This infection can be very painful for the horse and can even alter their landing to avoid impact on infected tissue. Landing may switch from the ideal heel first landing, to flat or toe first landings (which comes with its own myriad of biomechanical issues).

Such ambulatory/loading changes can alter heel growth (e.g., contracted heels, shown below), the overall perfusion of blood through the distal limb, caudal foot health, and the spiral continues.

These infections can be quite insidious, and can seep into the sensitive tissues, as well. It’s not uncommon for the internal structures, such as the frog spine (or frog stay) to be compromised due to infection progression.

Some Treatment Options

Soaks:

Vetericyn Hoof Soak

White Lightening soak (the gel is great, too)

EasyCare’s Clean It

Topicals:

Artimud: dress the frog generously, as you would condiments on your sandwich. This works great as treatment (can be done daily) and prevention (few times a week).

Silvetrasol Thrush Ender is a great spray formula that allows you to get all the small fissures and tissue insults. Apply as directed on bottle for initial treatment (typically a 2 week protocol to get ahead of the infection). If your horse has a central sulcus infection, simply place the nozzle head on the central sulcus and spray – this ensures getting deep into the infection. After the initial protocol, I encourage clients to follow-up with artimud or Silvetrasol Hoof and Wound as a safe step-down treatment after thrush ender.

Hoof Healing Clay is an all-natural, hand made clay which comes in a nozzle bottle for easy application to all infected areas.

Wild Hoof Equine Recommendations

I recommend irritating the infected areas with diluted chlorhexidine prior to treatment application.

But what about the purple or green stuff? I recommend the aforementioned products due to their non-caustic properties. There is a place for most products, though I’ve found most thrush products can be very drying and damaging to the healthy tissue. This can create microinsults to the hoof which often allows for bacterial reinfestation.

Other things to consider: if your horse is struggling to combat infections, despite appropriate topical and soaking protocols, it’s recommended to speak with your vet about the possibility of immunocompromising diseases, gut issues, and perhaps imaging (radiographs). And of course, check that their menu is appropriate for their needs and CLEAN (excess starch and sugar can weaken the immune system). *WHE is an advocate for forage based/species appropriate diets.

*WHE does not receive benefit from promoting these items – I just really like them because they work.

In Summary

Learn to identify thrush
Treat it with a soak (EasyCare’s Clean It, Vetericyn Hoof Soak, or White Lightening) and/or topicals (artimud, thrush ender, silvetrasol, hoof healing clay)
*all products linked above
If it won’t go away with proper protocols, speak with your vet to see if your horse may have an immunocompromising disease or gut issues.
Check their diet (excess sugar can weaken the immune system).

Learning to recognize thrush and taking proactive steps to mitigate such infections is a great move towards maintaining your horse’s soundness, health, and comfort.

No Hoof, No Horse! The Importance of Regular Hoof Care for Horses

Tue, 14 Jan 2025 08:54:42 GMT

As a horse owner, it's essential to prioritize your equine companion's hoof health. Regular hoof care is crucial for maintaining the overall well-being and performance of your horse. Neglecting hoof care can lead to a range of problems, from mild discomfort to severe lameness and even long-term damage.

Why Hoof Care Matters

Horses' hooves are made of a protein called keratin, which grows continuously throughout their lives. If not properly maintained, hooves can become cracked, chipped, or distorted, leading to pain and discomfort. Even more, the internal structures can fall victim to a myriad of pathologies. Regular hoof care helps to:

Prevent lameness: Proper trimming (and shoeing if necessary) can help prevent lameness and reduce the risk of injury.
Maintain balance: Balanced hooves support balanced wear (barring any body issues), reducing the risk of strain on joints and muscles.
Promote healthy growth: Regular trimming encourages healthy hoof growth.
Detect potential issues: Regular evaluation can help identify potential problems, such as thrush, inflammation, etc., before they become severe.

What Constitutes Regular Hoof Care?

Regular hoof care involves:

Trimming: Trimming every 4-6 weeks to maintain proper hoof shape and length.
If Shoeing: Shoeing every 4-6 weeks to provide support and protection for the hooves.
Evaluations: Regular inspections to check for signs of wear, cracks, or other issues.
Cleaning: Daily cleaning of the hooves to remove dirt and debris.

Consequences of Neglecting Hoof Care

Neglecting hoof care can lead to a range of problems, including:

Lameness: Pain and discomfort can cause lameness, making it difficult for your horse to move or perform.
Infection: Cracks and chips can become infected, leading to abscesses, white line disease, or thrush.
Long-term damage: Neglecting hoof care can lead to long-term damage, such as hoof deformities, chronic lameness, or dysfunction of the internal structures.
Coffin bone angle involvement: Studies have shown that at 4 weeks into the cycle, the coffin bone angle changes anywhere from 1.5 to 3 degrees. Shorter cycles allow for a more consistent situating of the coffin bone and internal structures.

TLDR:

Regular hoof care (4-6 week cycles) is the most efficient means to keep educated eyes on your horse’s feet and allows for more progress to be made at each trim.
Studies have shown that at 4 weeks into the cycle, the coffin bone angle changes 1.5 to 3 degrees. Shorter cycles allow for a more consistent situating of the coffin bone and internal structures.
