You’ll never believe what worked for me. After struggling with this for over a year and trying all kinds of supplements, my vet put my guy on a 30-day course of Metronidazole. The issue resolved quickly and hasn’t come back. He’s still doing great and will be 20 years old in just a few months.
A number of the horses at my barn had the same issue. I think most – if not all – cleared up with Metronidazole. Although, some required a 60-day course.
On it’s own, Metronidazole is pretty bitter. She went through a compounding pharmcay who mixed it with something that would make it more palatable. We just added to his feed every morning and he ate it up.
Not sure why it worked, but I’m so glad it did!
