I've never fed my pets iams or science diet so I can't give you any personal reviews. I have fed Royal Canin(bulldog and yorkie formulas) to my pets. They did well on both but I eventually exchanged the yorkie formula for Fromm because although my yorkie was eating the majority of his food he wasn't eating as much as I wanted him to. With the Fromm he eats every last bit! I advise you to research the brands first then decide on a formula. What may work for my yorkie may and probably won't work for the next person's. Also, online where are you looking to order from? We order all our pet food from Amazon and it comes with free shipping. I'm not sure if the free shipping is across the board or only with Prime. |
