So far we've been pretty lucky, its about 100 a month per horse. I'm stocked up on wormer, bute, and mineral blocks. I shop sales religiously. Grass hay is now 16$ a bale for the best horse hay around. This crap keeps them fat n happy. Nutmeg gets grass and then grass/alfalfa + vitamins. Give shots myself most of the time, and I don't call the vet out unless I really need to. Farrier is 40$ a trim per horse.
