The dosage for a horse
is 25mg (one tablet or caplet). My vet prescribed this and it was
confirmed for me by Heidi Smith at ROTR. My mare eats hers in her beet
pulp.
It works real well
when she is being driven crazy by gnat/midge hatches.
You must discontinue
feeding 3-4 days before a ride.
Apple cider vinegar and
garlic also help a lot with keeping the gnats/midges
away.
She also gets fresh
ground flax seed which is a great antioxidant.
