I really ditto, ditto, and ditto everything "Loosie" said.
My 17 yo TWH is insulin resistant and finally fell off the founder fence the second week of March because we had a few nights of frost, with sudden morning warmups and plenty of sunshine. I did not get the muzzle on him in time.
He rotated 8 - 9 degrees on the LF and 5 degrees on the RF.
While there is debate about my next comment, I will say it is working for this horse.
Boots --- trail riding boots with partial pads in them.
He WAS going out on 22 hilly acres every day, wearing his boots & pads, and a grazing muzzle. He was rehabbing fantastically.
Then the trimmer got chop happy and cut too much toe & heel off at once. The result was (the vet's words here) "severely strained flexor tendons".
I fired that barefoot trimmer and hired a very expensive and well schooled guy the vet gave his blessing on.
Once again, the first two trims were GREAT and the horse was on his way to healing. Thennnn, just like the barefoot trimmer this guy saw fit to REALLY chop my horse's toes off and take the heels too low.
A $208 dollar vet bill later, the ultrasound and x-rays confirmed a TORN ligament on the RF and sesamoiditis in both fetlock joints.
That was on July 21st. This horse is now relegated to the only flat place we have which is the half acre side yard by the barn. I don't know if he will ever heal up enough to go back out on the big hills with his herd mates.
My point is two-fold:
1. Trail riding boots with partial pads DO help ease the discomfort of the founder.
2. Educate YOURSELF a little bit on trimming procedures, pray you get a farrier that clearly takes the time to look at the entire horse and trims those hooves accordingly, so it doesn't suffer further damage.
My horse is one in a thousand that just cannot have his toes cut too short (the live sole is STILL exposed from the butcher job on July 19th) and due to his pre-existing fractured sacrum, he can't have his heels "lowered to spec" either.
When the equine chiro came on August 14th to work on this horse, she was really aghast at how he had regressed. I pulled Joker's boots so she could see the shreds of his toes. Her very quiet and emotional comment was "my poor Joker cannot take one more insult".
My only saving grace is that I know how to trim. Due to old age, plenty of arthritis and feeling like this horse needed a lot more expertise than mine, I trusted other, better schooled people than me to help him.
These folks are well-schooled/certified professionals but, they evidently didn't believe me or the vet when we said THIS horse cannot be trimmed to the standard short trim, you tend to do.
Evidently neither of them had ever run across a horse like Joker before, so they didn't listen and now I am left to pick up the pieces and pray this horse will at least heal enough for my niece to take a 15 minute ride whenever she comes to visit
Sadly, the trimming is back on me; with Mr. WTW's help, I trimmed this horse, ever-so-little yesterday. He isn't trimmed like the pros would trim him but he is trimmed to how HE wants his hooves to be.
While I now have to trim all four horses instead of just two, I get another $120/month back in my checkbook to spend on the medical supplies I need to poultice/wrap this horse every-day-twice-a-day for Lord only knows how long.
While I did get off on a big vent here, my point is, especially since you don't know the entire health history of this horse, to please do some reading on founder. Be explicit that the farrier does not take too much toe/heel all at once.
Lowering her too much, too fast, can possibly result in those strained flexor tendons my horse suffered with the barefoot trimmer.
It's really important the farrier isn't so arrogant that eventually he/she stops listening to you and the vet. They know a lot but, just like all the rest of us, they don't know it all; even if they think they do
