Hi. I just wanted to comment on this horses feet.
I see some things that could be changed to help you and the horse regain some soundness and some other things that the farrier can do to have a better foot. It may not be everything concerning soundness as we only get a small snapshot of this issue here with a few hoof photos but if you can eliminate these thngs, you can narrow the problems down.
Here is what I see...pardon the crappy drawing. I suck at paint freehand.
Firstly. I would bet dollars to doughnuts the horses unsoundness is directly influenced by a thrushy peeling of the frog and thrush holes as I circled in red at the back of the frog. All the feet pictured make me suspicious of a thrush infection in the succulous. Some look worse than others and some deeper than others. They all looks peeled and like they have been wet or trimmed alot so the frog can't callous up.
I would take a Q tip and explore and clean out those holes well of any nasties and then treat with Thrush Buster DAILY, not weekly like the bottle says. It will kill any nasties immedaiatly, dry it out if the horse is allowed time in a dry environment and keep them away while the frog grows the infection holes out. It will taek a bit of time for this to happen.
Secondly. The red circle at the toe...the farrier has commmited a pretty big sin in my book and his rasp has went past the white line and into the live sole at the toe. It isnt as bad as I have seen before but it should not have happened. Any thinning of the live sole at the toe can be problematic potantially and if he knew this horse is having lameness issues he should have been more careful. He wasnt trimming to set a shoe here.
The thin blue line is approximately where I would start a 45 degree bevel of this foot and I would keep it beveled strongly for awhile while the imbalances and flair grow out. They arent terrible but they are there.
Also the farrier committed another sin in my book by taking the heels down to clean corners and into live sole again. I bet this horse is ouchie on rocks after being dropped down onto thrushy frogs and half his frog cut away. Farrier should have left the healthy frog and opened the succulous so you could treat the infection better. Backwards. Healthy frog tissue should never be cut away as a rule. It needs to compact into a good callous over time. Unless its thrushy and infected and needs opening to treat it, leave it alone!
Diet. This horse clearly has metabolic and diet related issues. Im betting sugar somewhere, probably grass. Whats this horses weight like? Get those in hand and I see a gorgeous foot waiting to get out.
Another big thing for me...I hear you all saying don't blame the farrier..but I do. Its HIS JOB to be well informed enough to do a good job, leave the horse with a BALANCED foot and inform the owner when there is a problem like thrush starting etc. If the horse has an angular deformity or conformation issue, he should be reasonably able to tell you how it is affecting the horses hoof also so you know what is going on. This guy has had 9 months and the horse is having soundness problems and has a poopy foot that the owner is left to come here to find out about. I think its less than stellar myself and Id find a new farrier personally. This is how I came to learn to do this myself. Paying someone else to put a crappy trim on my horses and make them lame. I thought to myself, if ANYONE was going to lame my horses, it would be ME and for FREE LOL...Thus started my journey into the equine hoof and how to grow a healthy foot. My horses are now sound. I found out SO much that the farrier was not telling me including on of the worst cases of thrush I ever saw even to this date one of my mares had and I NEVER knew and was NEVER told about by any farrier I ever used. Anywas...tangent.....
I can grow a whole new foot in 9 months on my client horses. IF the owner listens to my advice and follows it generally (the ones who don't I can only do so much with of course) , I can have a pretty pathological foot looking really good and be sound in that time (usually less) easily.
This foot, 9 months later is HIS product, that is his work that produced it./... especially if he has said nothing to you about the laminitus rings, flairing and imbalance. It is his job to let you know what he sees and address these things as they appear. He is either not educated enough to know better, or doesnt care.....and in my book, THAT is his fault directly.
Im not anti shoes or anti farriers. In fact I use rubber shoes myself when I need to even tho im a bare trimmer...Im PRO healthy feet and well educated hoof care practitioners who can help owners get the best out of their horses feet whether they shoe or trim.
No foot no horse right? Its important.
JMO. Hope your horse is doing better. PM me if youd like a really detailed line drawing so you can understand what is going on with these feet.
