My older mare, who is Insulin Resistant and heading
into her 23rd year, has had what looked like black poop on her butt and back
legs for about 10 days. She seems normal, her poops look good and I
can't figure out what's the problem. Tried to hose it off today and the
texture was like a thick, tarry substance. She gets only grass hay and
plenty of it and is supplemented with beet pulp ( a pound) and maybe an ounce
at most of rice bran, daily. No grazing, carrots, nothing. Her
energy level was normal on our ride today (3 hours--beautiful, sunny
day!). So, any ideas? I'd sure appreciate your thinking.
