I've seen it in mares--well, not scabs, but particularly for mares in heat, when the stickier discharge comes out and stays in contact with the skin for a good while, I've seen hair loss and irritation. But I've never seen that develop into a secondary infection, nor a fungus, nor have I seen a gelding that urinated on himself to the extent described, unless he were dying or something. Even if he did
pee on his legs, it should, theoretically, bead right off and not cause any problems....
