I used this product in the puppy formula and our 5 month old puppy really seemed to like it. It was as if he couldn't get enough. He did have some gas when we first put him on it but other than that it was really good. It has really helped optimize his growth. The main downside to this product is that it is a little pricey. Although it is made specially for puppies so I guess the price is worth it if you have the money.
