Yes, my dex is prescribed by the vet. I give him an update weekly/bi-weekly and we see how we can alter his medications. I spoke with him today and we'll be continuing the dex for a couple more weeks, but he will be taken off his bute provided he doesn't come up in pain a few days later. Communication is key, and he did tell me of the side-effects. He was actually more worried about toxicity rather than laminitis.
He'll most likely be weaned off the dex before he gets gelded. But due to his head injury, we'll have to work out a dex schedule a couple days before surgery. The anesthetics may cause inflammation, which may irritate his head injury so we'll have to try and get him as comfortable as possible and he'll be staying at the vet for the rest of the day to ensure a safe waking up.
There on the tips of fair fresh flowers feedeth he; How joyous his neigh,
there in the midst of sacred pollen hidden, all hidden he; how joyous his neigh
