My new horse has been at my barn now for about 4 weeks. Initially was pooping “normally,” but has since started having diarrhea. Is getting orchard grass, locally grown and not much different from what he was getting at his old barn. Lots of watery projectile before formed poop. Has been vetted, dewormed and is otherwise a happy camper. BTW a few of the other horses in the barn are also poopy right now. Summer grass is pretty eaten down, so not likely from that. I’ve started probiotics daily.
Is there anything anyone has tried that works or do I just wait it out? Vet says “wait and see.” Horse came to me slightly underweight and unfit. Is gaining nicely and in 5 day/week training program. Stalled at night and on turnout all day. He doesn’t seem uncomfortable, is amiable to workload and eats hay and ration balancer/flax meal enthusiastically.
