I can't find much online about it, so I figured I'd ask you guys!
My mom has a 26 y/o Appy mare. I believe she has acquired contracted tendons in both of her hind legs since instead of angling back her pasterns angle forward. She has had it for a long time in one of them, and when I asked my farrier and vet about it they brushed it off as the way she was standing (it was very slight). Now it is very noticeable in both hind legs.
They don't seem to bother her, she is still sound and moves no problem, I just don't want them turning into a problem. (I took her on a little trail ride today and she was a complete spit fire). When she moves or shifts her weight (like when I pick her hind feet out) her pasterns flex fine like they are supposed to, it's just when she is standing they kind of buckle forward.
Does anyone know what the possible causes/treatment/prognosis of something like this would be?
