I found this forum by doing a search on the internet for this topic. My gelding rolled and got a piece of cactus in his hock. A 3/8" piece worked it's way out but the exit spot is still oozing. He has been on antibiotics but those are done now.
I saw someone had this same problem but it was back in 2004 and the links didn't work.
Any suggestions, ideas greatly appreciated. We are now in Washington state and my local vet may not be that familiar with AZ cactus injuries.
Thanks in advance
