Outlaw Thrush Stuff

Outlaw Thrush stuff was made out of necessity because no other product on the market was working for my clients.

I am a farrier of thirty two years and have been telling clients to pick out the feet and use thrush medicine that just wasn't working. I was fooling myself thinking it was lazy client or just dumb luck that certain horses are prone to thrush because of hoof conditions or stall conditions which is also environmental conditions. So I made it my mission to make a product that works not sometimes but every time. This is how Outlaw Thrush Stuff was made. I have been using it for twenty years and recommending it for twenty years. Now I have the opportunity to offer it to everyone and their horses.

Example of Treating a Horse with Severe Thrush

Why you need Outlaw Thrush Stuff. First off, horses with Thrush can be extremely uncomfortable or even in pain. Horses are extremely stoic not showing how much they hurt. A horse uses the frog as a support structure for weight bearing and to pump blood in the hoof which stimulates hoof growth. Compromised blood flow in the hoof inhibits growth. If the frog or heel is riddled with thrush every time that hoof touches the ground it will cause pain. Their whole personality and demeanor is affected if you hurt you would be grumpy also. It is our job as caregivers to do everything possible to help identify and treat infections in the hoof. That's where Outlaw Thrush Stuff comes in. We are effective at all stages of thrush. Thrush Stuff will treat the worst cases of thrush or gentle enough for routine maintenance of the hoof. As an antiseptic it treats the root cause and as an astringent it changes the moisture in the hoof tissue to stop reinfection of the compromised tissue. This allows healthy tissue to grow in creating a sound and functional hoof. Outlaw Thrush Stuff will not burn or sting the Sensitive tissues of the frog or heels. Which makes it easier to apply to sore feet. Outlaw Thrush Stuff should be your go to thrush treatment. Every conscientious horse owner should have a bottle of Outlaw Thrush treatment on hand.

Factors to Creating Thrush in Horses

There are many factors that go into the correct conditions to allow thrush to thrive in a horse's hoof.

Let's go over some of them.

Thrush, also known as Black Hole, Seedy Toe, Wall Fungus, or Gravel Pockets.

Thrush is an anaerobic bacteria that lives in all dirt. This is the absence of oxygen that this bacteria will thrive in and moisture is key. Ok now we know what it is and how it can grow in a hoof.

Simple horses stand in manure and urine along with dirt which gets packed into the hoof. A well functioning hoof just by walking or running during a ride or turnout will shed the dirt that packs in the hoof allowing oxygen to kill the surface thrush that is exposed. Standing in the stall there is not enough movement to clean the bottom of the hoof and oxygenate the tissue. This is why farriers say pick out your hoof regularly. I have been asked why my horse has thrush. His stall is clean and extremely dry, what is it that is causing him to have thrush. Simple you ride in dirt and a horse's hoof has internal moisture and you have the perfect combination for thrush.

Unique Design

Outlaw Thrush Stuff was uniquely designed as a treatment that will not sting or hurt the sensitive tissues of the horses hoof. When thrush is present it compromises the tissue of the frog, sulcus of the hoof, plantar cushion and possibly all aspects of the hoof function. The hoof is extremely sensitive at this point to cleaning, pressure, and picking out manure. Extreme caution should be made not to injure the sensitive tissues any further. The active ingredients of Outlaw Thrush Stuff have been used in dermatology for decades with great results and no sting or ill effects. We have formulated Outlaw Thrush Stuff to be gentle, non-stinging and effective for horses hoofs in all stages of infection. It can be used on open raw tissue without hurt or sting to the horse or minor cases that just need a little help. When your horse needs treatment the only one to turn to is "Outlaw Thrush Stuff" a product that has been tested, proven gentle and effective.

Conditions of Thrush in Horses

Thrush problems for horses are essentially fueled by poor hygiene, moisture and dirt. It's difficult to realize the seriousness of something that appears so subtle, but due to the horse's hoof construction, it can be dangerous if not dealt with properly with Outlaw Thrush Stuff. Horse hoof thrush can cause excruciating pain and lameness.

Characteristics of Thrush in Horses

Thrush is fairly easy to diagnose based on the telltale dark, blackish discharge and foul odor similar to yeast odor or bad bread rising odor. This is the bacteria breaking down the hoof tissue that can lead to pain in the hoof capsule, bruising and general discomfort for the horse.

If you smell a foul odor while picking your horse's feet, chances are he has contracted hoof thrush, a frog-eating, anaerobic bacteria. You need to treat the thrush in the horse's hooves as soon as you notice the first sign of this menace. With Outlaw Thrush Stuff.

Understanding the Horse's Hoof

As a farrier trimming the sole and frog is very important it allows the hoof to work properly shedding dirt and manure also allowing access to the hole frog and heels of the hoof to place Thrush treatment in reaching the infected sites not just treating the manure packed in the hoof.

Preventing Thrush in Horses

Move your horse to a dry, clean area. The first step in treating thrush is to remove your horse from the environment in which thrush tends to flourish. If you keep your horse in a wet or dirty environment the thrush is likely to return, no matter what treatment options you use.

Contributing Factors of Thrush

Thrush is usually developed on damp or dirty ground, whether in a stall or a field or pasture. Pick out urine, manure and dirt on a daily basis. Horse wastes can be a contributing factor in developing thrush in the hoof.

Try spreading gravel or shavings on the ground. This will allow your horse to keep its hooves dry, even if the floor of the stable or paddock is wet. Trim the frog of the hoof. Once your horse is in a clean, dry area, you'll need to have the frog trimmed on the infected hooves. This will get rid of the affected area and permit better air circulation across the hoof, also allowing access to apply Outlaw Thrush Stuff. This will also improve the chances that the thrush will not return.

Understanding Benefits of a Clean Hoof

The use an antiseptic and astringent to clean the affected area. Now that you've removed the visible dirt and debris from your horse's hooves, you'll want to clean the affected area and treat it with Outlaw Thrush Stuff. Others suggest treating thrush with bleach. However, it's worth noting that harsh chemicals can dry out your horse's hooves, which may make them prone to further injuries and afflictions. Outlaw Thrush Stuff is not harmful to the hoof tissues. Thrush Stuff is formulated to penetrate the hoofs nooks and crannies of the necrotic tissue not sit on the surface like some powders do.

Maintenance of the Hoof

After trimming the affected area of the frog, you're ready to clean the hoof. Cleaning the hoof should become a daily part of your horse maintenance going forward, as it will help prevent injury and reduce the chances of thrush returning in the future. Be careful, though, as the horse may be in considerable pain, and cleaning out its affected hoof may frighten or anger your horse.

1) Use a hoof pick to pick out any larger debris from the affected area.

2) At this point you can pack the affected area with cotton.

3) Then apply Outlaw Thrush Stuff by squirting it into the sulcus of the hoof, which are the V-like indentations that make up the "valley" of the hoof's frog.

How to Apply Outlaw Thrush Stuff - Video

Always use clean gauze or cotton balls to the sulcus to cover the medication. Use a hoof pick to pack the gauze as deeply as possible into the sulcus without hurting the horse.

Change the packing every day for one to two weeks. The only times you should not have any medication or packing on the sulcus is during exercise or riding sessions.

Depending on the severity of the infection, it could potentially take several weeks for the hoof to completely heal. Be patient and keep the hooves clean and treated with Outlaw Thrush Stuff.

Suggestions After Thrush has Healed

We also recommend the use of a bar shoe after the thrush has healed. If you were previously using a standard horseshoe or no shoe at all on your horse's hooves, you may want to consider switching to a bar shoe once the affliction has healed. In some cases, using a bar shoe has helped the frog regenerate after being trimmed and treated with Outlaw Thrush Stuff.

1) A bar shoe is a horseshoe with joined heals. It forms a continuous loop, usually made of either aluminum or steel.

2) Bar shoes can help improve ground contact, protect the hoof, and stabilize the overall hoof. This type of shoe should only be used in severe cases. Look for signs of pain. You can usually tell when a horse has hoof thrush based on the way it walks and reacts when you clean the hoof. A horse afflicted with thrush will show pain whenever pressure is applied to the area, which may result in limping or even lameness in severe cases.

3) In really advanced cases of thrush, the lower limb may swell up in response to the infection. If this happens, you will need to treat the thrush aggressively to ensure that your horse can fully recover. Always consult a Veterinarian when lameness is present in your horse.

Give Your Horse Some Dry Footing

Give your horse some dry footing. Wet and/or dirty footing is one of the leading causes of hoof thrush in horses. If you keep your horse outside in an enclosure and the ground is constantly wet, let your horse come into a barn or stable stall from time to time to allow the hooves to dry out. You should also keep the stable and paddocks clean and as dry as possible.

1. Muck out manure from the stalls and clean or dig out the urine spots on a daily basis.

2. Spread gravel or shavings in the paddocks or on the floor of the stable so that your horse can stand on dry footing, even when the ground underneath is wet.

3. Exercising your horse regularly along with function anatomy of the hoof.

Regular exercise can help prevent thrush in horses. That's because movement expands and contracts the hooves, which can push debris out of the grooves in the hooves.

Even if you can't turn out your horse in an enclosure, hand walking your horse or going for a ride on dry ground can significantly reduce the chances of thrush developing.

How Thrush Affects a Horse's Frog

Thrush is a bacterial infection that occurs in the tissue of the frog, the V-shaped structure located between the sole, wall and bars in the heel area of the hoof. The disease begins when bacteria penetrate the outer horn tissue of the frog. As it progresses, the frog tissue deteriorates, looking uneven and ragged and producing a smelly discharge and odor. In severe cases, the bacteria can reach the inner tissue of the frog, this is the sensitive tissue beneath the frog, causing pain and lameness. You may even notice blood on the end of the hoof pick when cleaning the frog. The frog has two distinct layers: the horn tissue and the corresponding vascular layer of tissue is called the sensitive corium. Beneath the sensitive layer lies a pad-like shock absorber that reduces concussion for the horse's hoof and his entire limb, called the deep digital cushion. A healthy, well-formed frog is broad and fleshy.

A healthy frog shares the load-bearing function with the other structures of the hoof and helps to absorb concussion. This in turn stimulates ongoing frog health. A well-shaped frog also has a natural self-cleaning mechanism. When it comes into contact with the ground, it expands, pushing accumulated dirt and debris out of the frog sulci, the grooves on either side of the frog.

An unhealthy frog is recessed, shrunken inward from the surface level of the rest of the hoof and is smaller in size than it should be. This can occur for a variety of reasons, including genetic abnormalities such as a clubfoot, and farrier issues such as a horse with sheared or high low heel sindrom. The fundamental problem usually involves the frog and heels of the hoof capsule not being on or close to the same plane. This limits the frog's contact with the ground and can reduce the stimulation from the ground surface, causing the frog to atrophy.

The recessed frog does not share in supporting the horse's weight, so it shifts too much of the load bearing back onto the heels of the hoof capsule. Initially, your farrier will also treat the thrush much like a dirty wound, trimming away the loose, diseased frog tissue and applying Outlaw Thrush Stuff. Once the frog is back on the same plane with the rest of the hoof, it will become healthy and should heal quickly.

Thrush is likely to take over a hoof that is left in unsanitary conditions. A wet environment that consists of urine and acidity from decomposing manure is a breeding ground for the anaerobic bacteria that are attracted to any dead compromised tissue that exists on the horse's frog. The bacteria will form deep seated pockets and literally drill into the frog and dead tissue, eating away at the remaining healthy tissue.

Despite what some people think, thrush is not caused directly by unhygienic conditions. It only develops in horses with unhealthy frogs or compromised hoofs.
