I've dealt with this and still am for different reasons on the same horse
I don't know why such a sweet/willing/compliant/in-your-pocket horse has to be the one frought with so many problems.
You know the saying "If I had a duck it would drown"? That would be Joker
Those strained tendons from the heels being cut too short are most likely something you will have to deal with, the rest of your horse's life. That means standing over top the farrier, no matter how good that person is or how much you trust them. They need constant reminder to NOT cut those way down because cutting heels way down is what they do -- just like the beautician who cuts your hair too short after you've warned them not to
^^^Joker never could have an excessive amount of heel come off, in one strike, because he has a fractured sacrum that affects his way of travel ---- on those slightly sickle-hocked legs that do better barefoot because he twists himself right out of a pair of shoes, after about three weeks
Joker sees a chiropractor 2 - 4 times yearly, depending how many times I can afford.
^^^Joker also has torn (I MEAN torn) tendons on the front from the nice re-hab farrier (serious founder) taking too much heel in one strike. The very angry vet did ultrasounds - very angry because he spoke to the AFA certified farrier, regarding how he wanted this horse trimmed.
I ended up flat on my back in April, could not get to the barn to save my soul. That meant ^^^Joker did not get his foundered hooves rasped every few days to keep his heels low and his tendons "un-strained". My trimmers come every four weeks but that horse still needs his hooves rasped 2 - 3 times weekly.
When the trimmers came in early May, the brother who trims Joker took off what was needed to keep Joker at what is normal for him.
Well guess what, Joker pulled up two legged lame due to too much strain on the tendons. He is that sensitive.
Meaning, if I don't keep his hooves filed and those heels shaved a couple millimeters 2 - 3 times weekly, Joker will end up lame with tendon issues. He will live with that the rest of his life.
I can't ride anymore and he is not ridable for the kind of riding I like to do. Even if we were both able get out on the trails, I would not shoe him. He wears Boa trail boots to pasture, and he'd wear them on the trails.
Shoes or boots, it's whatever works for you in your environment. All I'm sayin' is be prepared to deal with this forever after as there are some horses that shaving just one or two millimeters extra off the heels is going to cause them to come up sore or lame
If your horse puffs up, Animalintex pads work great or the cheaper but more laborious route would be Sore-No-More cold poultice of bentonite clay and arnica. It can be vet wrapped - I've vet-wrapped it for the last two years not only on ^^^Joker but on my heart horse with hock/ankle arthritis.
Leave it on at night, cold hose in the AM, slather some Gel-Flex from Cox Laboratories, on for turnout and the horse is "limping better" for at least 20 minutes
I'm not trying to sound crass -- lol lol lol This stuff gets old and frustrating with enough passage of time
Joker is not going anywhere but, mercenary that I am, I can at least be grateful he just turned 19 instead of nine
<sigh> Bute <sigh> be careful of ulcers. ^^^Joker now deals with mild ulcers from all the bute he had when he first foundered but, his founder was a real doozy - it's a wonder he didn't sink on the LF.
