Thanks.... it would seem if timing were important, though, it would be pretty clearly spelled out.
Or it could be that I'm just an idiot. :)
I found this in my Equine Science textbook:
As soon as signs of laminitis are noted in a horse, a vet should be called. The horse is usually treated with drugs to decrease the inflammation. Special pads are put on the sole to support it. Early in the course of laminitis, special shoes can be put on the feet to elevate the heel and take pressure off the deep flexor tendon that is responsible for the rotation of the coffin bone. Hot and cold water soaks are often used to increase circulation to the lamina and cool the feet. This also helps make the horse more comfortable. The stall should be deeply bedded to help cushion the feet.
