I agree with all the good advice given. My dear departed mare first started showing symptoms, as seen in hindsight, about 5 years before her disease had progressed to the point that I had to euth her. Unfortunately, by the time there was an accurate diagnosis (mutliple local Vets had no clue), she was in too bad of a shape for the nutritional protocol mentioned to do much good (it had just been developed too, and apparently works better the sooner it is started). Concurrent with the onset of symptoms, Dr. K and the EC/IR list had helped me make some dietary changes as maresy was iron overloaded, per KSU iron panel and although a lean and rangy body type, was showing an IR type of cresty neck. She did become compensated IR over a 2 year period of nutritional management however.
Anyway, the symptoms, that seemed unrelated at first, included, a puffy hind fetlock, some stiffness, stumbling that was only partially helped by short and rolled toe trims. It did not help her any that my at the time 15 year old and disobedient, willful Stepdaughter who did not live with her Dad and me, decided to ride her without my permission. The ride, per boardersâ report later, was much longer than the mare was fit for and in deep sand without leg support. Said SD also weighed at least 230 lbs at the time (I hover around 100), and was/is an extremely unbalanced rider, so that was a doubly hard workout for the mare, poorly balanced weight above and bad shifting footing below. The way I found out about this the next day, God bless fellow boarders, was to hear from a few of them about her unscheduled visit and ride. Kallie also had what appeared to be, and I treated as, a suspensory strain in a front leg, surely related to that wild ride. She had to have some stall rest, standing wraps and handwalking and gradual return to work. Considering the overall systemic breakdown in connective tissue, even though she apparently returned to soundness, I strongly believe that overwork episode hastened the progression of her disorder, or at least the disorder resulted in continued weakness of the structures in that leg.
That disorder progressed, or declined, into her standing with hind legs over a period of years becoming increasingly placed farther under her body until she eventually became quite postlegged, becoming progressively over at the knee in front, more puffiness in hinds and one then the other hind fetlock began sinking. By the time one of hinds was showing signs of falling fetlock, she began doing a âbunny hopâ of both hind legs together cantering loose or on the longe, or having her hind leg or legs seem to slip out from under her, one of those times resulting in a scary fall for us both. She began lying down less, and having more trouble getting up. She had trouble holding any of her legs up long enough for hoof trims, farrier fortunately was very patient with her and let her rest as needed.
About a year after she had started stumbling, she also was showing signs of âshiversâ in which one hind leg would be held up, haunch quiver and after a few minutes sheâd put the leg down. Oddly enough, she only had that symptom for just over a year then it spontaneously stopped. By the time I euthâd her, which was probably a little later than I should have waited, she was not able to bend hind legs much at all, had become really post legged behind and over at the knee in front. Throughout this ordeal she remained cheerful, interactive, affectionate, and bright eyed, until the day she was no longer bright eyed and I sent her over the Bridge. She was a grand mare, truly my heart horse, and I miss her daily.
