I'll share my experience here - remember, I am not a Farrier either, nor do I trim my horses feet.
I had a Farrier for about 2 years doing Nelson's feet - I never paid much attention, because he was the professional, so I trusted him.
Over this period of time, Nelson started reaching short, tracking up, landing on his toes - I didn't realize it was his feet, I thought it was because he was getting older and needed Injections.
He couldn't keep a shoe on either. He would throw a shoe within weeks of just being done. Dry Brittle Feet, thin soles, all that stuff that goes alone with incorrect angles.
This is what his feet looked like at that time - believe it or not, these pictures were taken after he threw a shoe, after a few weeks of just being done. During an 8 week period, he would have 0% growth. NO heels *my Farrier at the time said that is just how TB's are and just accept it for what it is* and very thin soles. My Farrier had no where to put new nails, beacuse of the old holes from previous nails being put in.
So - one fateful day, he threw a shoe - yet again. I called my Farrier to come and do an emergency shoeing, but he couldn't - he was on his way out of state for holiday....so I had to find another to come and put his shoe back on.
I found one, thankfully. He showed up and took one look at his feet and asked me "when were his feet last done?" I said - just a few weeks ago - and he was shocked.
He took me threw the steps of where his feet should be, the angles and the percentages of where what should be and how. From his heel to his breaking point and from his breaking point to his toes. He showed me how his angles should be in accordance to his pasturns and his shoulders and hips.
He also showed me how much pressure were in his toes. He proceeded to walk up to Nelsons left shoulder and he did some massaging - and Nelson almost collapsed due to the pain. He told me that is because of how poor his angles are.
So he started to do corrective shoeing with Nelson. When he pulled his toes back, you should of seen how much blood and bruising was built up in them from how off his angles were.
We had our 3rd session already, and are awaiting our 4th on the 1st of July. I'll get pictures of his new toes for you to see the MASSIVE difference.
Nelson now has short toes. He now has heels growing. His frogs are opened up, and his soles are thickening up with growth.
It is all about Blood Flow! I've learnt so much just from my new Farrier.
Nelson also, during the time of the previous farrier - wouldn't land on his heels, because he had none, nore did he trust them. If you watch him under saddle even to this date, he will still land on his toes because he hasn't figured out that he can trust his new growth of heels.
BUT he is now tracking up much more easier than he was before. I don't need to inject his hocks - because that wasn't the issue, it was his incorrect angles that were causing the problems.
I have a new horse because of this :) And I am very thankful and blessed to of had my eyes opened!
