No problem! It's very well possible it could be worms! Are goats will tend to be like that when they have worms so! :D

Well I say call a vet because you never know what people say on the internet.

Plus there is the health issues. Diarrhea can lead to dehydration. Constipation can lead to impaction colic. If he is impacted or dehydrated a vet can put a hose down his nose into his stomach and pump him full of water or something along the lines of castor oil which would help loosen things up.

And being that there is such a quick dramatic change, I would be calling the vet if this is my horse. A horse poops approximately every 15 minutes. Are you going to be available to constantly help him poop? If the answer is no then he is more than likely going to get impacted.

I understand what you're saying and I agree. This forum was more for advice other than the obvious take him to the vet. We are friends with his owner and know that he has been to the vet before and we will continue to take him if he doesn't get better. But so far the vets he's been to haven't helped so I was looking for more out side the box thinking. But thanks for your concern :)

When our foals get constipated, rare occurrence but does happen, we usually give a warm water enema to loosen things up. We don't out enough in there to hurt, but enough to help get things moving. If he's tried a lot of different medication, the constant changes had probably weakened his digestive system. I would try giving probiotic paste to see if that helps. I wouldn't deworm if he's sick because the poison may hurt him when his immune system is compromised. If he's switching between diarrhea and constipation, then his gut is pretty messed up. I will try to get him straighten out there before worrying too much about his weight. As long as he isn't losing any, I'd focusing on lining out his digestion.
