Below we will discuss how to fix this, but first, let’s discuss what a heel crack (Sulcus Crack) is:
A “heel crack” (an opening into the sulcus) is the number one warning sign of thrush. These cracks are not natural. In fact, they are wounds created by bacteria as it seeks a way to get inside the foot. The tissue between the heel bulbs is soft and pliable, so the bacterium burrows in and creates a breeding ground. This breeding ground is warm and moist inside, so until we completely eliminate the crack, we should expect a thrush invasion at least 3-4 times per year.
Normally people only treat for thrush when they see and smell the “black goo.” But with sulcus thrush (thrush inside the crack) you can’t see or smell the goo – so you literally don’t know it’s in there. Often, though, what you do know is that your horse is mysteriously going “off” several times a year. Perhaps you start treating muscles, hocks, and stifles, but the horse is just…well…. off!
In the case of sulcus thrush, the horse is Off because his heel is infected and he is walking with a toe-first landing. He can’t land on his heel. If he is a barrel horse or jumper, (or any sport horse), he absolutely can not perform at his best because he can’t properly plant his foot in the sand.
The result of toe-first landing???
That barrel horse will take wide crow-hopping turns, ruining your time. The racing thoroughbred must shorten his stride to avoid the pain (not good in a race!). The worst scenario is for jumpers and eventers. Every time that horse takes a jump he will take extreme impact on an improperly angled foot. That is guaranteed to cause soft tissue damage in his legs. At our Rehabilitation Centre we’ve seen dozens of incredible Jumpers lose their career due to this.
There is a solution. We can help regrow the heel back to its healthy (closed) state with NO THRUSH Powder.
Before we start the “product Talk,” let’s discuss exactly what occurs inside the Heel Crack
WHY ARE HEEL CRACKS THE PRIME CAUSE OF RECURRING THRUSH?
Simple answer… Because when we horse owners no longer see the black goo we stop treating. We think we have beaten back the thrush and we move on to other things. But the truth is, that was a temporary fix because tomorrow a whole new host of bacteria will find its way back in there. There is no way around it. Then, when moisture is introduced via rain, urine, or even water bucket slop-over, thrush has everything it needs to restart the infection process.
WARNING: If you have been using a liquid thrush product, whether you buy it or make it yourself (ie: Bleach) be sure to research the ingredients. If it is caustic, do not use it on sulcus thrush. The term “Caustic” means that the PH level is excessively high or low. If it is caustic it will, of course, kill bacteria – however, it also damages live tissue. EX: Bleach, even a 10% solution, absolutely destroys open tissue.
Now we are going to discuss how to use NO THRUSH ® Powder to solve this problem and get from point A – to – Z.
Clean the foot with your pick. If the footing is damp, use a rag to wipe off any excess moisture. Puff the powder into the clefts, around the shoe, and then brush it in with your hoof brush. MOST IMPORTANT: Puff plenty of powder into the heel crack. Don’t be shy. Use your hoof pick to wiggle and manipulate the powder all the way inside. Your horse might be sore from the infection. If so, be as aggressive as he will let you. Over the course of a few days, the lameness will lessen as the product dries up the sulcus tissue and you can get more firm with your application.
In normal circumstances, it will take 3-5 days to kill all the thrush bacteria. (No more black goo or smell.) See the photos below to see a terrible case of Sulcus thrush
DAY 1: All this thrush is internal. This is the worst because you can’t actually see the black goo. The actual frog and sole look fine. The thrush lurks below!
DAY 1: Dusting with NO THRUSH Powder. Note how the powder is wicking up the moisture inside the sulcus? It works that fast.
DAY 4: This is great progress. The crack is closing and the heel tissue is reconnecting properly. Also, his heels are much, much firmer. He is no longer lame. NOW ON TO STEP 2!
No! We are not finished. We have killed the thrush – but now we need to get the heel closed up and “healed.” If you stop now, a new troupe of bacteria will jump right back inside the crack.
Fortunately, step two is simple. Just keep dusting. Dust the frog and clefts and get the powder into the sulcus crack. Dust 3-4 times a week until the crack heals over. With a typical case, this should take 20-50 days, depending on how deep the crack was. One note on this… If you have been previously using a caustic thrush product, it will have damaged the internal tissue. This means that it will likely take a bit longer to get from A-to-Z because it takes time for that tissue to recover and become viable again. Just be a bit patient. After working with thousands of thrush cases I have never seen a sulcus crack not regrow properly. NO THRUSH® will also help the clefts regrow. A horse prone to thrush will almost always have collateral grooves that are too deep around the frog. Be sure to always dust the clefts as well as the heels. NT will help the cleft regrowth.
Thrush is not “curable.” Once a horse has thrush, he is susceptible. When we look around our barn, it’s obvious: Some horses get it, some don’t. So once we have eliminated the active thrush and repaired the heel crack, it is good practice to continue using NO THRUSH® on a regular basis (We recommend 3-4 times per month). The powder will keep your horse’s feet healthy and firm, and thrush-free.
SOME FINAL WORDS:
Once we come to recognize the patterns of thrush and frog disease and understand how the heel crack plays a crucial role, we will catch the warning signs far in advance. We will readily notice gait changes and temperament changes. In short, we will become proactive instead of reactive. This proactive attitude will save time and money. A year’s worth of maintenance is far less expensive than one call to the vet.
Thanks for stopping by. I hope this was helpful. If you are struggling with a case of thrush and have questions, we can help. Call us. I’m pretty sure we can help. With over 70 horses at our Sport Horse Rehabilitation and Reconditioning Centre, I’m pretty sure we have seen it all.
I guarantee the story below will make you Barrel Racers, Ropers, Jumpers and Eventers take a closer look at your horse’s feet. We are once again in the midst of thrush season. This is not a sales pitch, it’s a true story. It can make a difference to so many of you. The attached video is included to give you the visuals.
Long story short – if your horse has a heel crack, there is a problem.
Thrush is a MUCH bigger deal than most think.
** Early this Spring I was manning a No Thrush booth at a big barrel Race. I was chatting with a pretty young woman about how and why heel cracks are such a problem. She was clearly a big hitter in the racing world, as all the little girls nearby were goggling and pointing in rapt attention. The woman and I finished up our chat and she said she would take a look at her horse’s feet when she headed back to the barn.
A few hours go by and she stops back by the booth. “Wow,” she said, “I checked my horse’s feet and both hinds have big cracks between the heels [the sulcus area between the bulbs]. Honestly,” she added, “I’ve never noticed them before. I just thought the cracks were normal. A lot of my horses have them.”
I asked her to show me.
At the barn we picked up the front feet. They both looked great. No cracks, no problems. I asked her to push on the bottom of the heel bulbs and they were nice and firm.
We picked up the back feet and there they were. Narrow but deep cracks in between the heel bulbs. There was no visible thrush whatsoever – none of the black goo in the clefts that most people associate with thrush. In fact, she didn’t see any of the black goo so thrush was the furthest thing from her mind.
I asked her to push on the bulbs. They were soft, almost squishy. Finally, I slipped the hoof pick inside the crack and it came out black and smelly and gross.
The young woman put her hands over her mouth and her eyes went wide. In a horrified monotone she said, “I am the best horse mom on this planet. How could I have not seen this?”
She then turned even whiter, a realization hitting her, “This horse is my rock star. He’s my main horse. But for the last six weeks we have been horrible! We are nowhere near the money. Are you saying THRUSH could be the problem?”
I nodded, “Think about it. Your horse has infected heels. That means they are soft and sore. When you start your run, you are expecting him to plant that sore, infected heel into the sand and make a hard turn. He won’t do it. He can’t. Instead he will only plant his toe, which is not good enough to hold the torque of the turn. His feet will slip out of the sand. I’m guessing he is taking his turns too wide?” I asked. She gritted her teeth, blew out a frustrated sigh, nodding.
We dusted her horse’s feet twice that day, twice the next day, and once on the morning of the 3rd race. She and the horse came in third – in the money for the first time in ages.
Obviously No Thrush powder didn’t “regrow” the heel crack in 3 days. But it did absorb and eliminate the damp thrush breeding ground that had infected his heels (without damaging the live tissue because it is not caustic.) Ultimately, the heels firmed up and he was able to plant his feet properly into the sand.
Important Note. No Thrush powder is going to get rid of the sulcus thrush fairly quickly. BUT please don’t stop there. That heel crack is made by thrush. It should not exist. If you just stop treating as soon as things are firm, bacteria will head right back in there, keeping you forever in the “Thrush Cycle.” So keep dusting until that crack regrows. Take a look at the video or the photos at the No Thrush website. It is supposed to be a “Dimple” not a “Crack.” This regrowth will typically take 20-50 days, depending on the severity of the crack.
Once you get back to the dimple, you will want to dust once a week for prevention. Thrush is not curable. A thrushy horse will always be susceptible.
Another note: If you have been using caustic store-bought products, or things like bleach or peroxide to combat thrush, these products will kill live tissue as well as the bacteria. Please, please do not use these inside an open sulcus crack – and Definitely do not “soak” with anything caustic. If you do it can take many months for the deep tissue to recover and begin to grow back into the proper dimple.
Here is an example: You would not willingly put your cut hand in a bucket of 10% bleach water every day. It will sting like mad, it will damage the tissue at the edge of your cut, and the result will be a jagged, ugly scar that looks like nubby proud flesh. Not good.
No Thrush – PRO TIP – July 2015… “**Shedding Frog**” We received a private message from a woman whose horse was shedding its frog. The answer is valuable, so we thought we’d share to all….
While frog shedding is normal, if you have never experienced it, it can look scary. In fact, sometimes the entire V of the frog will shed at once, which really looks daunting.
Usually thrush is the procuring cause of the shedding.
Here is why: Thrush wants to invade and live deep inside the heel tissue, and of course you can’t see it or smell it because it is so deep. [This is why we preach so hard about eliminating the heel cracks and deep collateral grooves. These are bacteria access points.] — Anyway, when the thrush has run it course deep inside, this action can undermine the frog.
However, when active thrush is present, the frog tissue will literally hang on for dear-life. The body does not want to allow it to shed because it is the only protection for the soft, tender, and vulnerable tissue underneath. ….
So here is the No Thrush “tip.” —- If you see the frog begin to shed [ perhaps an edge, or even a big section looks to be dislodging and “flappy” under your hoof pick] get aggressive with your No Thrush dustings. Once per day is best. The powder will draw out the deep bacteria and breeding ground and take care of the “thrush” problem. If the thrush was severe, and the frog has been undermined, the rest of the frog may fully shed away. This is a good sign. This is the body’s way of breathing a sigh of relief. It no longer needs to fight the thrush, so the body allows the necrotic/dead tissue to fall away.
But you are not quite done…. Keep using your NT every few days. This will help firm up that new tender tissue and allow it to regrow properly. No Thrush is not caustic, so it will not inhibit natural grow…. As the new frog continues to grow you can slowly back off. The A-to-Z timing will be based on the speed of your horse’s natural growth rate. [usually 20-50 days] No Thrush is not “making” the tissue grow, it is “allowing” it to grow. Meanwhile the powder is protecting the new/tender tissue from being invaded by a whole new round of thrush.
Most people don’t think much about thrush until their horse’s foot is black, smelly, and the frog is mushy. Yet they wonder why the horse gets thrush 3-4 times per year. The Truth: thrush is a bigger deal than most think. Here is a brief video that gives full details about warning signs, facts, and shows exactly how the thrush bacteria breeds inside the foot. Here is a cliff Note: Look for Heel Cracks…. Heel cracks are bad!
