Good luck with everything you’re trying to accomplish! I have replaced bute with Absorbine “buteless bute” at the recommendation of a natural hoof care farrier. She told me that in her experience it was a valid substitute. I don’t know for sure since she also trimmed my horse’s sore club foot at the same time, but for whatever reason my horse is walking much better. This was an abscess rather than a laminitis situation but just wanted to share the bute info. -- Susan H TX 2021
