I have a mare that poops - a lot! She poops nearly constantly while being ridden. She will poop at least 10 times on an hour long ride. She sometimes only poops out one ball, but it always has gross juice with it. I've never had a horse that pooped so dang much. Is this normal at all?
Activity stimulates the system, even in a horse w/out a never problem -- if your horse has nerves as well, then you have elimination overdrive. The fact that her poos are passing in single balls and have a juice factor is overactive elimination, not just normal activity stimulation. Overall, it's not a big problem - if/when it becomes excessive enough that her hydration and nutrition suffer from the excessive elimination, then it's time to worry about it.
