I'm currently reading my much-abused copy of How to be Your Own Veterinarian by Ruth B. James, DVM, and learning a whole lot. Regarding the treatment of leg injuries that require stall rest, blistering/firing is mentioned, and to me, it seems completely pointless. I can't see why you would fire a horse and am in shock that it's considered acceptable by some vets.
Opinions? Experience with it? I'm very curious to learn more.
