Well, I had a good long conversation with the vet - on the phone. He's slammed. Talked about when he could come out and spend a good long while diagnosing and ended up not till Monday. He is repairing a broken leg all day tomorrow that he was called into today, he's doing a knee surgery Wed, and so on and so on. Given that kind of schedule it sounds like he doesn't really need my money this week either ;~D LOL.
We ruled out laminitis that would mean he has to come out right away... doesn't make sense, and he's taking my word for it on the symptoms. (doh! should have asked for his email, I could have sent the video)
Here's what we decided to do: Medicate the heck out of him this week as if it's his Navicular and see what he does. Give him 20 Isoxuprine twice daily [he's been getting 14 in the morning only] ~and~ two Bute tabs twice daily every day this week. Give him nothing Monday and he'll be by to see him at 1:00. If he's relatively sound after all those meds, then evaluate whether he should be xrayed, continue to be treated with meds, talk about different shoing options, or maybe even the injections to his foot, and whatever other options make sense. If he's not sound after all those meds then it's not his navicular.
I think it's good that by then, my shoer will be coming the same week anyway, if changes there need to be made.
I'm glad to hear you reached the vet and that he okayed meds for him. Did he say anything about cooling his feet?
