If he needs longer term pain relief, I had success using B-L pellets on my mini mare with laminitis issues. It comes in pellets, paste and solution; I use the pellets as they are easy to add to their daily feed. [Your fellow is a boy, so the don't give to pregnant mares precaution isn't a problem for you.] My girl was uncomfortable enough that she needed bute for a week before switching her to the B-L pellets, which she was on for 6 months (she was doing so good, I was afraid to take her off them, but finally did and she was just fine).
