Foot Focus Webinar Series - From Shod To Barefoot With David Greenwood, Sarah Logie & Mark Trussler
I thought Iโd give it a listen. I knew it wasnโt going to sway heavily barefoot with the guests being farriers.
A few things I picked out:
(bold the point, not bold my views)

Thatโs if they even trim them at all. So many just say โah theyโre fine they can wait until next timeโ yet that is leaving the hoof unbalanced. In my experience it takes the farriers I have seen about 30 seconds to trim a barefoot, compared to 5-10 minutes with somebody who specialises just in barefeet.
- ๐๐จ๐ง๐๐จ๐ซ๐ฆ๐๐ญ๐ข๐จ๐ง interesting that barefoot wasnโt a big no no but more about the horse itself and whether barefoot or shod would be best for the horse.

- '๐๐จ ๐ฒ๐จ๐ฎ ๐ก๐๐ฏ๐ ๐ญ๐ข๐ฆ๐ ๐ญ๐จ ๐ญ๐ซ๐๐ง๐ฌ๐ข๐ญ๐ข๐จ๐ง ๐ฒ๐จ๐ฎ๐ซ ๐ก๐จ๐ซ๐ฌ๐ ๐๐ฌ ๐ข๐ญ ๐๐จ๐ฎ๐ฅ๐ ๐ญ๐๐ค๐ ๐ฎ๐ฉ ๐ญ๐จ ๐ ๐ฒ๐๐๐ซ?' If you want to go barefoot then you need to be aware transitioning takes time, even for the more straight forward horse. It all depends on diet, current state of hooves, what surface you can offer, any injuries, implications, management and exercise. It takes roughly 9 months for a new hoof to grow.
- '๐๐ก๐๐ญ ๐ข๐ ๐ฒ๐จ๐ฎ ๐ญ๐๐ค๐ ๐ฒ๐จ๐ฎ ๐ก๐จ๐ซ๐ฌ๐ ๐๐๐ซ๐๐๐จ๐จ๐ญ ๐๐ง๐ ๐ญ๐ก๐๐ง ๐ฅ๐๐ญ๐๐ซ ๐ข๐ญ ๐ ๐จ๐๐ฌ ๐ฅ๐๐ฆ๐?' (๐๐๐ซ๐ค ๐๐ซ๐ฎ๐ฌ๐ฌ๐ฅ๐๐ซ ๐ซ๐ก๐๐ญ๐จ๐ซ๐ข๐๐๐ฅ ๐ช๐ฎ๐๐ฌ๐ญ๐ข๐จ๐ง) I hope that like any other time when a horse goes lame when shod you get the vet? I think he was suggesting that youโd need to put shoes back on, but is this just covering a lameness and not getting to the root cause? Now I canโt say for sure thatโs what he meant, but what an odd thing to say/ask.
- '๐
๐จ๐จ๐ญ ๐ฌ๐จ๐ซ๐ ๐๐๐ง ๐๐ ๐๐๐๐๐ฎ๐ฌ๐ ๐จ๐ ๐ญ๐๐ค๐ข๐ง๐ ๐ฌ๐ก๐จ๐๐ฌ ๐จ๐๐, ๐ซ๐ข๐๐ข๐ง๐ ๐ข๐ญ ๐ญ๐จ๐จ ๐ฆ๐๐ง๐ฒ ๐ญ๐ข๐ฆ๐๐ฌ ๐๐ง๐ ๐๐ก๐๐ง๐ ๐ ๐ข๐ง ๐๐ง๐ฏ๐ข๐ซ๐จ๐ง๐ฆ๐๐ง๐ญ' Zero mention of diet for this point which I believe itโs probably the number one reason why horses become or are foot sore. The foot also adapts to the environment it is in, so if the horse is always kept on grass or in a stable then its more likely their feet will be soft too and not the rock crunchers weโd desire. It can take years to develop โrock crunching hoovesโ and this is done through diet and expose to different terrain and surface.
- ๐๐ข๐๐ญ โ๐ ๐ญ๐ก๐ข๐ง๐ค ๐ฌ๐จ๐ฆ๐๐ญ๐ข๐ฆ๐๐ฌ ๐ข๐ญ ๐๐๐ง ๐ข๐ฆ๐ฉ๐ซ๐จ๐ฏ๐ ๐ฌ๐ญ๐ฎ๐๐, ๐ข๐ง ๐ฆ๐ฒ ๐๐ฑ๐ฉ๐๐ซ๐ข๐๐ง๐๐ ๐ข๐ญ ๐๐จ๐๐ฌ๐งโ๐ญ ๐ฆ๐๐ค๐ ๐ฆ๐ฎ๐๐ก ๐๐ข๐๐๐๐ซ๐๐ง๐๐. ๐๐จ๐ซ๐ฌ๐๐ฌ ๐ ๐จ ๐ฎ๐ฉ ๐๐ง๐ ๐๐จ๐ฐ๐ง ๐ข๐ง ๐ญ๐ก๐ ๐ฌ๐๐๐ฌ๐จ๐ง๐ฌโ. It is well documented that diet plays a huge role in hoof health. This can easily be seen by event lines in horse hooves which correlate to change in feed, change in grass or even when a wormer was given, not to mention the integrity of the white line. To keep a hoof healthy, sugars and starch should be kept low - this is a well known fact now. Diet plays a massive part in the horseโs health, hoof quality and behaviour.
- '๐๐ซ๐๐ฏ๐๐ฅ ๐ ๐๐ญ๐ญ๐ข๐ง๐ ๐ฌ๐ญ๐ฎ๐๐ค ๐ข๐ง ๐ญ๐ก๐ ๐ก๐จ๐จ๐' Yes, this happens, itโs happening right now to my horse. After he escaped on nice grass and was on it for several weeks in winter without restriction the outcome was weeks later his white line became stretched allowing stones to creep in (he also became footy so I used Trinity Consultants L94). Itโs part of the life of being barefoot, figuring out what works and what doesnโt and what triggers changes in the feet. But thereโs things that can be done starting with diet and keeping that white line tight, the use of hoof boots, and of course hoof armour or vettec which got no mention.
The good bits - which were all from the same farrier, Sarah Logie. A farrier that was very open minded, and put the horse first.
-' ๐๐ซ๐๐ฌ๐ฌ๐ฎ๐ซ๐ ๐๐ซ๐จ๐ฆ ๐จ๐ญ๐ก๐๐ซ ๐ฉ๐๐จ๐ฉ๐ฅ๐' now this swing both ways but I think itโs important to not let others around you pressure you into methods you donโt think is right for your horse. โWhat youโve got to do is up to you to make best of it, you donโt need to feel guilty because it doesnโt sit in the ideological boxโ.
- ๐๐ก๐๐ง ๐ฌ๐ก๐จ๐๐ฌ ๐๐ซ๐ ๐ง๐๐๐๐๐ Sarah used one of her own case studies where the horse was barefoot but had gravel runs and therefore to help fix the problem the horse needed shoeing but once the problem was eradicated, the shoes were removed. The horse then had another injury so was shod appropriately but once healed went back barefoot and is now out competing BE90 barefoot.
- '๐๐๐ค๐ข๐ง๐ ๐ก๐จ๐ซ๐ฌ๐๐ฌ ๐ฌ๐ก๐จ๐๐ฌ ๐จ๐๐ ๐ข๐ ๐ญ๐ก๐๐ฒโ๐ซ๐ ๐ง๐จ๐ญ ๐ข๐ง ๐ฐ๐จ๐ซ๐ค ๐.๐ . ๐๐จ๐ซ ๐ฐ๐ข๐ง๐ญ๐๐ซ ๐จ๐ซ ๐ซ๐๐ญ๐ข๐ซ๐๐' I like this idea but I feel like its something of old times, do horses really have seasons off these days? I know several people with retired horses but they choose to keep them shod.
I felt like Sarah is the kind of farrier we need more of!
It was a shame that some of the questions the questions the public put forward werenโt answered or were muffled out. I donโt feel like this webinar was a true โShod to Barefootโ it didnโt represent both sides fairly. It was also a bit shorter than I thought but I do appreciate itโs a Monday night webinar and they are farriers not vets, body workers, etc. But hats off to BHS (Scotland) for acknowledging barefoot is more common now and for trying to educate on it.
๐คHorse Shoes: Do they shut down the natural hoof mechanism?
And even if they do, do we actually care?
Well YES - we absolutely SHOULD care!
That is of course, as long as you understand what the natural hoof mechanism really is, and why its correct functioning is so VITAL to the horse.
And only then will you fully understand why metal horse shoes ALWAYS have a negative affect on the hoof properly functioning.
This cadaver hoof shows how by removing the shoe and setting the hoof up with a natural trim, with natural toe lengths etc, could have set this horse up to heal, by engaging the natural hoof mechanism.
๐If you think shoes have absolutely NO affect on the horse whatsoeverโฆthen perhaps you should read on!
What is THE HOOF MECHANISM?
The hoof mechanism can be defined as the hoof naturally contracting and expanding, whilst it goes through the weight bearing (support phase), and the non weight bearing (flight phase).
It happens on EVERY single step your horse takes.
Or at least IT SHOULD! ๐ณ
The correct functioning of the hoof mechanism is incredibly important for the efficient circulation of blood, not just through the foot, but through the leg and entire body.
When it is all working correctly, it helps blood flow back to the heart, against gravity - and the more efficient it is, the less strain the heart is under.
Good BLOOD FLOW is absolutely essential - without it, the structures within the foot, and within the body, will simply begin to sufferโฆ.
โฆ probably way before YOU are even ever aware of it.๐
Every step your horse takes, is either bringing health - or bringing pathology - closer and closer.
The correct hoof mechanism is also incredibly important for the LYMPH SYSTEM to do its job correctly too - removing waste from cellular activity, moving important molecules around the body, and of course helping the immune system to fight off infection.
๐งSo what happens when you add a metal shoe to the hoof?
A metal shoe is a rigid structure. That goes without saying, right?
It is applied to the hoof in its most contracted state (the non weight bearing flight phase) - with the foot in the air!
As soon as the shoe is applied, nailed into place, and the horse then puts the foot down, the natural expansion and โspreadingโ of the hoof to facilitate shock absorption is immediately impaired.
โผ๏ธIMMEDIATELY impairedโผ๏ธThat is serious.
Consequently, when the hoof is then lifted off the ground, entering back into the flight phase again, the venous return of the blood back up the leg, is markedly reduced.
One relies upon the other.
Unlike humans, horses have no help from the skeletal muscle โpumpโ from the knee or hock down - because the horse has no muscles there to help that blood flow back to the heart.
Or the lymph to function correctly.
๏ฟฝThat is why it is absolutely ESSENTIAL that the horse keeps on MOVING.
๐We are astounded that this salient fact is simply MISUNDERSTOODโฆ
โฆ or worse - IGNORED!๐คทโโ๏ธ
Whenever we talk about the debilitating effects of the rigid metal shoe to the horse, and how it affects the hoof mechanism so profoundlyโฆ
โฆ some people just donโt WANT to listenโฆ or they tell us we have no clue what we are talking about!
They will even tell you that putting a shoe on a horse helps with caudal supportโฆ supporting the pathological hoof to give the horse that much needed comfort.
From a metal shoe that disrupts the vital hoof mechanism? ๐คฆโโ๏ธHmmm.
The problem with that way of thinking is that they simply ignore all the serious problems the shoe causes.
๐If you believe, wholeheartedly, that disrupting this vital natural hoof mechanism, is not of any concern, then tell that to the 1000s upon 1000s of horses with navicular and caudal hoof pain.๐คฅ
So many horses have been successfully rehabbed by taking the debilitating metal shoe off, and going barefoot, with the right diet and management. And we highlight such successes in The Barefoot Horse Magazine in every issue.
We have a MANTRA:
โ ๏ธโDo unnatural things, and expect unnatural things to happen.โโ ๏ธ
Donโt go it alone, and keep listening to misleading โadviceโ.
For instance: a โremedialโ rocker shoe helping a laminitic hoof is an oxymoron.๐ตโ๐ซ
Weโve seen this cycle so many, many times.
Disrupt the hoof mechanism - and it is only a matter of time before you DO begin to notice the effects - don't let it be too late!

COPPER - IS IT SAFE TO FEED OR NOT?
I have been asked to write a post about feeding copper to horses. Working as a minerals analyst, I see more horses with copper deficiencies than excesses.
COPPER IS AN ESSENTIAL TRACE ELEMENT. That means it is necessary for the health of your horse. Copper is needed for enzyme production in the heart, the synthesis and maintenance of tendons and ligaments, mobilises iron stores, melanin production - dark coloured horses required more, normal skeletal growth, cell production for energy stores.
It's easier to understand why is is so essential if I explain deficiency symptoms which include: orange tinge to coat, poor coat, hoof problems, pale skin around eyes, more susceptibility to worms/parasites, hormone issues such as irregular cycling, unexplained lameness, ostochondritis and osteochondrosis in young horses, fertility issues, greasy heel, seedy toe, wind sucking, weak tendons and ligaments. NOTE: CHEWING TREATED PINE POSTS IS A SURE SIGN YOUR HORSE REQUIRES COPPER. Treated pine uses copper as a wood preservative and arsenic so chewing or licking treated pine posts also gives your horse an unhealthy dose of arsenic!
IS COPPER TOXIC? There has been a recent study in Journal of Equine Veterinary Science, Nov 21 which investigated the deaths of horses in Brazil. 15 horses were affected by copper toxicity, death recorded in some. The cause was found to be chicken litter used as a fertiliser and crops sprayed with a copper product. According to KER" most cases of copper toxicity in horses is from environmental exposure" (KER Sept 21).The upper limit of copper for horses is 250mg/kg daily (NRC guidelines) This is a lot of copper! Interestingly, horses are more tolerant of copper excess than sheep or cattle.
HOW MUCH COPPER to add to your horse's feed? This is dependent upon the workload, iron stores, soil type and colour of your horse. Some minerals such as zinc and iron affect copper absorption. For example, many horses in Australia have an excess of iron mostly due to soil type and this can reduce copper levels. If your horse is getting a zinc supplement be aware that zinc and copper need to be in balance. A safe estimate provided your horse is not getting any other copper in a mineral mix and without testing to be sure is to add approx. 1/4 of a measuring teaspoon once per day per feed or approx 1.5 grams. Other sources of copper in hays, pastures, grains etc are minimal as most Australian soils are low in copper and that is why it is ESSENTIAL to add to feeds.
WHAT FORM OF COPPER? It is stated to never inject copper unless under strict veterinary supervisions and advice. Otherwise all copper supplements should be added to feeds. There are a few debates about which forms of copper are best. Copper sulphate (bluestone) which is what all us oldies ever used for decades without any ill effects. Copper carbonate which is a stronger form and not recommended. Copper oxide which is very inexpensive and less absorbable. Chelated copper more expensive and some views that it is hard on the liver and a seaweed derived copper which has varying levels of elemental copper.
COPPER EXCESS In many years of testing horses, I have only tested 3 that has an excess of copper which is not the same as copper toxicity. On investigation these horses were exposed to copper via the spraying of vines and fruit trees with a copper solution called bordeaux. All 3 horses had copper induced anaemia, severe liver stress, off feed, lethargic yet spooky behaviour, unexplained scouring and gastrointestinal distress. I also am of the view that copper in excess is mostly caused by environmental exposures.
Many horses I test ARE DEFICIENT IN COPPER and present with all the symptoms of copper deficiencies. It needs to be added to the diet as it is An ESSENTIAL TRACE ELEMENT at a dose required for your horse. Do not be led astray by relying on adequate copper levels in mineral mixes which are not reliable and rarely provides your horse with the amount of copper it needs. IT IS SAFE TO FEED and vital for your horse's health. BEST TO TEST FOR ACTUAL DOSAGES REQUIREMENTS for your horse on your property.
