Today after church, I went to get my horse from the back pasture and I noticed that he has a small wound on his lip. At first it looked like a large pimple or something. I squeezed it and something popped off/out(skin or something???) and it bled a bit. I was scared that he might have been shot with a bb gun or he poked himself? He dosnt mind me looking at it. He is due for his tetanus shots. This is what it looks like. Sorry it's blurry.
