This seems like a great product, and from a trustworthy manufacturer. I have no problem feeding it to my picky puppy, along with his normal food.My only suggestion to the manufacturer is: why not a squeeze dropper cap, so people can easily measure out how much they want to dose. As it is, its a little messy and oily, and it could be much easier. In fact, I'll probably replace my bottle with a generic dropper bottle from CVS.
