Debs,
There was a woman on this site that told me about it (sorry don't recall who it was) and she said her vet swears by it. I'm a beliver now too! They have a website and I believe it's www.underwoodhorsemedicine.com. If that's not it, do a search and you'll be able to pull it up that way. I was going to order it from Mr. Underwood and actually placed my order on-line. The medicine was $16, but he called cause the shipping was going to be $10. He said there was some stores in my area that sold it and that I could probably get it cheaper. I thought it was very, very nice of him to call and save me some money when I'm sure a lot of people wouldn't have let me know where I could buy locally. You could call Mr. Underwood and ask him if there's anyone in your area that sells it and he can let you know. I ended up paying $19 for it and it's well worth it. Pixie is nearly healed and I still have a lot left for future emergencies. I figure it'll work on dogs and cats too.
