So I went to go give Skip hay this morning, and he was hobbling around. I got out there and his fetlock is larger than normal (not severely swollen) and slightly warm. I gave him 3 tablets of bute mixed into his grain w/ maple syrup to get him to eat it. Im skipping school today to go get him some sawdust, and check on him throughout the day. When I walked him in, he would put weight on it as soon as we got out of his pasture (its covered in snow, w/ some ice from friday underneath) Im going to stop @ the vets when I go to get sawdust, and Im going to call my friend and see if I can borrow her digital camera to take some pics of it. Do you guys have any ideas what might be going on?
