OMG, I don't think I've ever seen something like that. Wow, they just sprayed some crap on there and left it? Whew, I had an emergency vet call when my filly got a very clean gash about 1 inch wide, 6 inches in length. I would be in shock if I walked out to find my horse in that condition!!! Although, Im pretty sure any savvy horse owner wouldn't have left a horse tied to a FENCE in the first place. Poor thing, I hope the owners are brought to justice, although horray for them giving the horse to someone who was willing to spend the time on him!
