I already asked "fred" about this since shes' a farrier but thought i'd put it out here for a bigger population. Ok so I have a 3 year old colt that has locking stiffles. Last fall we had a very very muddy wet fall up here and He was locking up A LOT. to the point i really thought he was either going to have to be put down or have SOMETHING done. It was like every few steps he'd lock up and he'd have to fight with it or drag it around for a little bit. I gave him some "time" because i know it can be somewhat age related... Then winter hit and it seemed to go away almost immediately and he's been fine ever since. I was excited thinking maybe he'd outgrown it or something was just going "right" for him. I assumed it was the mud was causing him to slip and maybe make the ligaments in the stiffle malfunction. Well yesterday I trimmed his feet and he's a little bit of a turd and and likes to try to pull his feet away from you so i just held on. I felt the stiffle pop. He was locking up after and today. Since this i've got to thinking i did his feet in the fall i think before all this happend so badly. I don't remember him "popping" but maybe that irritated it.. ANYWAYS one way or the other i was wondering if having their feet trimmed and having their legs picked up in that possition causes it to flair up more or whatnot. Anyone observed anything like this?
