A couple of weeks ago my horse got caught up on something (we assume either a branch or wire), and he got a lateral cut on his right-front pastern. My dad and I treated it as best we could over time (i.e cleaning it, putting on cut-heal wound ointment, ichthammol, and wonder dust) but it's still not fully healed.
There is no swelling, he's not favoring that leg, I'm able to clean the hoof without an issue, and it is not oozing any fluid. However, the wound is constantly caked with dried mud. If/when I clean the mud off, I end up reopening it and the healing process starts all over. For the past 4-5 days, I have just left it alone and kept an eye out for any obvious signs of trouble. The flies still swarm on the area where the wound is, and there is still the caked dirt on the area where he was injured.
My question is, should I continue to leave it alone to let it heal? Or should I scrape the wound clean daily and risk reopening any healed tissue? Any advice would be helpful!
Oh, and we've tried to keep him corralled to prevent the wound from getting dirty, but out here (in AZ), it seems it's an impossible task.
