I think it was around the caves and cliff update that my horse starts looking like this. The horse texture looks like that in the based game. Even if you have texture pack on, the horse texture still look like a glitch. I tried searching for others who is suffering like mine, but I guess I'm the only one experiencing this. Please help me fix this, I would like to play Minecraft without a glitchy texture.
