We bought a horse 7 months ago. Poop was good when we got it. We wormed it a month after we got it. It started having diarrhea not long after that. We used proboics. It got better but not like the poop was when the horse got here. The horse got a infection. We used penicillian. THe horse, of course got diarrhea. Used probois. About 3 montha ago the horse still had diarrhea. The vet came out, did fecal check and blood work. The only thing was no bacteria in the gut. I understand, makes sence. He said use oats, and probois for 3 months. We have done this for the last 3 weeks. The poop did start to get like cow patties about 1 week later. Now the horse started eating grass 1 and 1/2 weeks ago. Pure liquid. We are still using probois. Nothing is working. We were just told today by our farrier to use beet pulp. PLease help, our horse is wasting away. He still eats and drinks fine. Please HELP!!
