One morning I noticed these black spots on him, more like gunk, I could get most of it off by brushing, but I was so confused as to what it was, I couldnt tell if it was a skin issue or if it was dirt of some kind. Then the next day I notcied more of it. Im thinking its from the homemade fly spray.
Has anyone else ever seen something similar on their horse? Maybe its from the vinager?
I had bought a bottle of Larrys concentrate and was going to make my BO's flyspray mixture, but now I don't want to since I think the vinager is causing this gunk. What can I mix in with the larry's stuff to make a flyspray that wont leave gunk? Would just water be alright?
