I usually gave my horses the Intervet Prestige V or just the Prestige V. If the vet is there, just ask him what he recommends or the minimal vaccinations he recommends to be show legal. I would definitely get the equine infuenza shot, hands down.
Thanks for dragging Raina down from the pasture for me. I would have loved to make it and ask questions but it was during work hours and no work = no horse! Let me know what he says :)
