Has anyone had a horse with this?  If so how did you treat them supplement wise?

Bump

It’s a genetic defect in the collagen, so there isn’t much that supplements can do. You can try an extended heel shoe, but we’ve seen them get ripped off the hoof more frequently than not.

What is it exactly, L?   I know I can look it up and I know I've read on here what it is, but I'm asking you instead!!!!

Degenerative suspensory ligament desmitis- it’s a genetic condition affecting the whole body of the horse, but most outwardly evident in the hind suspensories (it affects the collagen/connective tissue, causing the breakdown of the ligaments) which leads the horse to drop significantly at the fetlock, some to where they almost (or do) touch the ground. It most commonly affects Paso Finos, but can be seen in other breeds. There’s no cure unfortunately, and they haven’t linked it to any specific genes yet- but there’s still a lot of research being done on it!

That's what I thought but wanted to make sure I remembered correctly.  I wondered the first time I read about it if my mare could have it. . . 

Well hopefully she doesn’t have it, but if she does I hope it isn’t too bad yet! DSLD can lead to issues further up the leg (hock, stifle,etc.), and they’re even finding a correlation between certain metabolic disorders and DSLD (still not sure how it all links together though). If you look up videos of Paso Finos, you can see some great examples.

There is a product called AAKG that is a amino acid that some are using to treat it.  Google treatment for dsld

Yes I have read, read, researched consulted with Dr. Kellon who is doing research on DSLD and have looked into some products.  Presently I am trying 3 products from forloveofthehorse.com .  I give dosage morning and night, have been on the Arthritis formula for a year.  Now I give 3, the Arthritis formula, the Tendon formula and the Pain formula.  Both horses have the DSLD (or so I have been told by my farrier).  Still not sure this is what they have.  Their ankles and fetlocks do not look like what I have seen pictures of.  But both horses hind end fetlocks are swollen and kind of lumpy.  I cannot get the swelling to go down and it gets worse in this heat and humidity as they don't move around much, just stand in the barn in front of fans.  They are on pasture 24/7 and come in for their grain and supplements.  The formulas I give have to be given an hour after they eat their grain because they have other supplements in their grain.  This is done morning and night and it is becoming a pain.  When the weather is cooler I do see them moving around more and they seem to move better.  Before they were dragging their toes in the hind end and when they would step down they were stepping toe first.  Mine just started showing this in the past 3/4 years.  They did not show this when I was still riding them.  They are both retired. One is a 30 year old gelding and one is a 24 year old gelding.  Both were barrel and rope horses and were hauled most every weekend to a show or a roping.  Both were started as 2 year olds.  Way too young in my opinion which I think has caused some of this.  From my research still not sure it is heredity.  I think a lot of it could be from improper shoeing from too long of a toe and dropped heel.  My opinion only.  They both have issues when getting up from laying down and they have to stand for a while before they start walking.  They generally walk out of it but my 24 year old still acts a lot more sore (actually in the sole) of the foot than my 30 year old.  Both eat good, weight is good, hair coats are really good and nice and soft and shiny.  No processed grain, they are on Renew Gold, Omega alfalfa cubes, Bluebonnet Stride 101 vitamin/mineral supplement and Stride Rewind.  I have also been in touch with Dr. Schell from CurOst people and have ordered a new product which is Cell Repair ATP & NRF2.  They also have another new product called CurOst Sole & Tendon topical therapy I am considering but want to see how this Cell Repair works.  According to Dr. Schell DSLD can be hopefully halted.  Not sure about cured as what I have read there is no cure.  So I will probably be looking at some point in time if they don't get better on putting them down but for now I don't want to think about that as they don't seem to be in much pain.  I only cringe when they get up from laying down.  Sorry this is so long.  Also if there are any Farriers on here I would like to know if they have run into this and if so did they do anything different on trimming as to maybe pulling the toe back so it will turn over quicker.  

My vet has asked for roller shoes on back, along with a little heel support on the shoe. My farrier knew exactly what was needed so it must not be completely uncommon. I've seen rollers up front (on the same horse many years ago for a club foot) but never on rears. Something new every day, right?
