I think it would be too hard to do that because then he wouldn't be able to flex his leg all that well, and it might come off. It's in a really hard spot to bandage...:(
I'm going back to check on him in a little while. I'll get a picture of where it is.
My neighbor's gelding will bite mine from across the fence from time to time. Once he bit him right in the hollow where the horse's barrel meets the pelvic bone. You know, where the coat flows up instead of towards the back of the horse? It was deep enough that it needed first aid, a broad deep scrape. I got some wonder dust, and this silver spray on bandage recommended to me by someone at tractor supply. It worked GREAT! It covered and protected the area, wouldn't come off w/ sweat/rain, and stayed put for a few days but not too long. Once it came off, the wound had heald almost enough to be left alone minus one section that I treated with Corona.
