Wet Weather Hoof Care

Hooves didn't evolve to thrive in wet, squishy, muddy footing. Hooves can certainly adapt but you cannot expect peak performance during times when there is excessive rain. Hoof management becomes even more imperative during wet weather.

Here are a few tips and things to look out for, for owners and for owner trimmers.


An otherwise healthy hoof that has a thrush infection taking hold in the collateral grooves and all across the sole and laminar line.

Thrush is the #1 issue that hooves deal with in the wet. Thrush is a general term for anaerobic organisms that thrive in a wet smelly hoof. It is that stinky, black paste you can get on the tip of your hoof pick. Healthy hooves don't smell! If your horse's feet smell, it is probably thrush.

It eats away at hoof tissue - mainly in the frog and the collateral grooves (beside the frogs). Some horses can present with significant lameness due to an active thrush infection - some horses will loose their healthy heel first landing because the thrush infection makes the back of the hoof tender. Thrush infections can lead to abcesses and seedy toe/white line disease. If left, it can even eat away at the sole, causing a thin sore sole that can't protect the pedal bone.

The best way to deal with thrush is to be vigilant in wet weather with thrush prevention. This mainly includes topical treatment with a substance that somehow makes the environmental conditions in the hoof not ideal for thrush growth. I recommend spraying apple cider vinegar (just the supermarket stuff, not the expensive supplmenent stuff from the feed store, although this works too!) onto a clean picked hoof every day when it is wet. Make sure your horse has somewhere dry to stand, at least some of the time. This could be a shelter with sand, or a high spot with good drainage, turnout in a dry indoor arena, or even a stable with dry bedding where they can spend a few hours to dry out their feet. Giving the hooves a chance to dry out can often be the only way to help prevent thrush.

Once thrush takes hold though, I have noticed (in Sydney, at least) that ACV just doesn't do the trick to treat a thrush infection that is already established. My clients have had success with straight iodine sprayed &/or scrubbed onto the frog and collateral grooves every 2-3 days, along with picking the hooves daily to keep them free from the (normally helpful) dirt plug and having that dry spot to stand. Remember, thrush is anaerobic, which means it thrives in low oxygen. That is why it seems to take hold in deep crevices in the frog.

There are other products out there that I have seen work with varying amount of success - but the common factor in successful treatment doesn't seem to be what you treat with, but more how often the treatment is administered. Keep treating until there is no sign of thrush left - then start with preventative treatment if weather conditions still haven't dried up.

For trimmers, ensure there are no tags or flaps of frog that the organisms can hide under. I advocate minimal frog trimming except in cases where thrush may be an issue. Just open it up enough that the thrush cannot hide and you can treat it with ACV or iodine or your topical of choice. Sometimes you may find little pockets of thrush starting to eat away - or even find that your whole frog is about to peel off! Use your judgement - mostly with my clients I will leave as much frog as possible and advise treatment, and will return to trim again within a week or two.

Don't freak out if you see this! Just be aware that you need to treat it and provide hoof protection while the new frog toughens up.
Most of the time you will only need to remove little flaps near the central sulcus and along the sides of the frog. Don't remove any more than is absolutely necessary - we don't want pretty, we want functional!

Here is my own horse Allie - see the minimal trimming of the frog to open up the thrush infection?

Seedy Toe

A resection is a job for a proffesional - if you are an owner trimmer, get your mentor in to do this for you!

Seedy Toe or White Line Disease is where thrush or other bugs invade the tissues in the inner wall. It can spread all over the hoof, all the way to the coronet. Seedy toe can lead to serious abscessing that may even lead to pedal bone infection if left unchecked. It is a serious case that needs a professional in when it requires resection, but during your maintenance trims you can keep an eye out for signs of it starting and nip it in the bud before it becomes a problem. If, while trimming, you see small (or even large) black lines that cross the laminae line, take your knife and nick them out.

Click to embiggen - see the line there circled in red? This is what seedy toe can look like at the beginning.

If you have someone else trim your horse and they perform a resection, don't panic! It can look fairly invasive but it isn't. A resection allows treatment - ask your trimmer for specific instructions and follow them exactly. Your horse shouldn't need to have their workload altered unless there is a significant resection required. I have performed many many resections like the one shown above, and have not had one horse go sore because of it. There is a minor chance of a stick becoming lodged in the hole, but other than that it is life as per normal for the horse and yourself. As it grows out, just keep it dry and treated!


It is quite common for a horse to come up lame in wet weather due to an abscess. I hope you can see why after reading the above - your horse shouldn't abscess if he has been on a nice short trim cycle for some time and you are doing your thrush prevention.

If your horse is presenting as lame, and you suspect an abcess, I recommend calling in a vet to diagnose the abscess first and foremost. Your vet may use hoof testers to pinpoint the seat of infection. Some horses will not put their hoof on the ground if they have an abcess - but this is also a symptom of a broken bone. You need to rule out something more insidious first before you treat for an abscess.

For most cases, an abscess is a "wait it out" deal. You can poultice and your trimmer or vet may want to have a little dig with a hoof knife to try to relieve the pressure if the abscess is close to the surface, but most of the time the abscess needs to work its way out via the path of least resistance. Normally they burst at the coronet or the heel bulbs.

It can be very distressing watching your horse deal with an abscess - the pressure in the hoof can feel like when you slam your thumb in a door - very painful! Bute often slows down the proccess - being an anti-immflammatory. Give your horse somewhere comfortable to stand and lay down. Obviously, don't work him. You can poultice and use a therapy boot if you wish to speed up the process. Most of all, once the abscess blows, ensure you keep the area clean and free of thrush.

If after 2-3 days the abscess doesn't resolve, consult your vet.

Other Tips

During wet weather, your horse may have soles that are soft or even washed out and thinner than usual. You cannot expect your horse to have a level of soundness on par with dry times. Cut him some slack - if you are going riding on rough or rocky ground that he is normally ok with, take boots with you and put them on if he feels less forward than normal. Ride him on the verge where there is a little grass. Ensure you don't compromise that heel first landing. A horse landing toe first because of sore feet is doing damage to the navicular area.

Keep up the preventative treatments. A little bit of effort now will save you more effort and heartache later on down the track!

Shorten his trim cycle but take less off - leave a couple of mm of hoof wall above his sole for protection and grip in the wet. Check the weather over the next week before you trim - if it looks like periods of rain, give him a wet weather trim. If it is going to be dry, trim him for hard ground. You can always take more off if the rain doesn't eventuate, but it is very difficult to put some wall back on if he needs it in the wet!

Beware the flush of grass after spring or summer rains! This is a laminitis risk for horses that are prone. If you have a horse with a known issue, keep him off the grass!

The Future of The Glorious Hoof

For all you blog only readers, the last 12 months have been the busiest 12 months of my life. There has been some major learning going on, with 2013 being the year of Hoof School (also known as the College of Equine Podiotherapy in Victoria, Australia) and 2014 bering the year of Uni (I started a 6 year Bachelor of Equine Science at CSU).

My own horse has also had some major struggles over the last 8 months. Initially coming up lame overnight, she suffered a suspensory injury that actually caused a stress fracture of her left hind cannon bone. Recovery was slow. She was on box rest for a total of 2 months plus another 6-8 weeks (it is all a blur) of being stuck in a very small yard. But this was nothing compared to what was going on inside her face. We were starting canter work again when she got a bleeding nose one night, which led me to take her to the vet for diagnosis. It turned out to be a very rare form of dental tumour, called a complex odontoma. It had a huge impact on her sinus and teeth and was potentially untreatable, which meant euthanasia. After a CT scan, it was determined that the tumour was operable and so we went to surgery. It was a major surgery that happened 40-something days ago and we are looking at a possible second surgery due to some difficult complications. I still don;t know if I will get my mare back.

Last year, while studying, I picked up a huge amount of clients - I think at one point I was looking after something like 60 horses. Along with study and a full time job (not to mention my poor horse) there wasn't much room left for writing blog posts. But I realised, through Allie's illness, that life is short, precious and you don't know what is going to happen in the future. So I have drastically reduced my business to a much smaller number of horses and I have realised what it is I want to contribute to the hoof world.

I want to empower owners. I want them to be armed with knowledge, armed with rasps and know how to use them. Locally, I can help owners who want to trim their own horses, I can run clinics and I can share information on my Facebook page. But this blog has been grossly underused and I would love to write more articles for the owner who wants to know more about their horse's feet from a scientific background.

I promise to be as transparent and as unbiased as I can. I promise that the information presented on this blog will have scientific background or alternatively will have significant anecdotal support. I promise to keep the language as simple as possible. I don't want to sound smart - I want you to understand.

So what do you want to read about? What concepts do you find difficult to understand or what would you like to see ellaborated on?

Well well - this looks interesting!
Have a little read of this article then pop back over and let me know what you all think? (I'm on my iPhone so can't hyperlink, please copy and paste).

I would love to see them in action. I think I like them? Might have issues with thrush or keeping them clean and actually attached in wet weather. Would be great in dry conditions.

They look to be weight bearing in all the right places - sole, inner wall, frog (well, most of it), heels. Is this the holy grail the hoof industry is after? That elusive compromise between shod and boots/barefoot?

I must say I would prefer this over traditional shoes. I hope they live up to the claims.

Laminitic Pony

Just a quick one - below is the left hind of a laminitic pony I'm trimming right now. I suspect he has high ringbone too on this hoof.

Not only has the toe shortened dramatically, but the heel bulbs are of a much better quality.

What else do you see?

Owner Trimmers

I wanted to ask a general opinion of my readers here (yes, even you lurkers!) I this post.

Owners trimming their own horses - good or not ok?

We all know how I started trimming. I was 12 and my mother bought me a rasp. My pony had great feet and was in a LOT of work so he really was a great candidate for owner trimming.

When (if at all) is it ok and not ok for an owner to trim their own horse?

Discuss. I will post my full opinion soon.

Minor Coronary Band Injury

Here is something interesting. I am in the middle of trimming one of my own horses, Allie. About six months ago she had a knock to her coronary band that caused a wound that wasn't too major, so I thought nothing of it. Today while trimming I pulled my knife over it gently and the 'hoof' that seemed to be plugging it popped out. I think it was actually a piece of wood that had gotten stuck, or possibly it had been the cause of the injury and had not quite been removed by the body. Anyway, behind it was minor infection, but quite deep. I had to take my small knife and clear it out. Then I made the hole bigger so nothing else gets clogged in there.

It should be ok, but it is worrying as it is quite deep. There is no reason to pack it, I will just keep it clean and might give it an apple cider scrub every other day or so.

I won't make any changes to her work load, as her hoof wall is very strong and thick. I will keep the walls rolled and take care as it grows out.
