Bests & Worsts Reviews from Amazon

This product is great and works however buying it off Amazon not so good. When opened my dog got sick. I smelt it one day when giving it to my dog it had a bad smell like something was rotten. Called the number on the bottle. They said we weren't the first to complain about this and all were bought off Amazon. Company is sending us a new bottle. Not saying this product is bad just buy it from the actual company and not here.
