yesterday morning I found sheak in the barn with a swollen back leg. it looks like he may have gotten wrapped up in the fence or something. the inside of the hock (right in the bend) is all cut up. i was going to feel for heat but as soon as my hand got near it he drew his leg up. I stopped at the BO's house and told him what was wrong. he called his owner and I left. Well this evening his leg is still swollen and nothing has been put on the cuts. but the hose was out so maybe she cold hosed it. I'm just wondering about his leg b/c it is still swollen. could there be an infection in the joint? the cuts were mostly scabbed over today. what advice could i give her?
