There is no vaccine for horses for clostridia, but although there is a test that can be done, most vets look at foals with diarrhea at her age and guess clostridia -- and treat for it. They don't even test for it, because diarrhea in foals can be so life threatening they don't wait for the results.
I think I'd have another discussion with the vet -- because she is not having diarrhea at all, since the initial problem, and I'm kind of surprised that if she truly had the disease, I would think her diarrhea would continue past her 1 or 2 episodes. Instead, she's not pooping.
Something just doesn't make sense to me and I can't quite put my finger on it, as they say.......
I'm encouraged by the different poop behind all the black, tarry poop. I'm hoping we'll see more of that tomorrow -- it will certainly make me feel better. The enema should have made her feel better in the tummy, and hopefully some of her tail wagging will have stopped.
I would suggest that tomorrow you call and question the vet to discuss these past few days since she's been on medication, and let her know the diarrhea completely stopped after the first day, and she is not pooping but once every other day (in huge quantity), and then today with the enema (and describe it). Let them know she has good energy, is nursing well, is playing well, has no fever, etc., and see if they want to continue treating her for the clostridia -- or perhaps these past few days may shed some light on something else for them. I would speak to the equine vet, however, and
what I would do is prepare a "time line" on paper with the different things that have been going on -- and make sure you make them understand you are giving them the timeline of events so they can see how she has been reacting to the medication.
I'm thrilled that she continues to do so well, and that you are so attentive to her changes. You have saved her life, and we will work through this problem.
Talk to you tomorrow! I'm here if anything changes.
