Rated 5 out of 5 by from Great product, just hard to get ordered! I ordered it online and shipped it to the store. The store had to refund the purchase price and resell it to us because the online could not get the TAX EXEMPT. The store worked the problem and we got the product. it is great stuff!!!. We use it on our horses on the instructions of our VET. It does what it says it does and does it well.
