I honestly am not 100% positive what exactly my mare ran into, as she got hurt several years before I got her, but my vet was pretty positive that someone put her behind barbed wire fence, and she tried to jump out. The wire cut her left front leg just below the knee, in the front, and seriously scarred up both her hind legs, surprisingly just in the front. She had criss crossed scars running from her hocks down to her fetlocks. Fortunately for her, she was a dark bay, so the scars didn't show up much until you looked closer, though there was one place where the hair had grown back, but it had grown in white. Normally I would actually put Gall Salve on any cuts my horses got, and it always seemed to work well, but again, I've never had any serious cuts. Just really bad punctures, and one horribly torn tendon. My mare was a pro at puncturing her legs, as well as her hip once. Where it is, being right below her fetlock, I personally wouldn't wrap it, but like others have said, def. ask your vet.
