My pup has been on this food since we brought him home 6 months ago. He is happy and healthy. Hill's has done more research than just about any other company out there. Also, don't get so hung up on the "chicken meal" aspect-- it is an efficient way to include chicken. Think about it-- how do these companies like Blue etc. actually include wet chicken into dry food? They don't. They process it. People knocking Hill's for including chicken meal need to get a grip. Let your common sense be your judge. This food is balanced, not over-proteined like a lot of other brands, which can actually do long term damage. My dog is energetic and goes #1 and #2 just fine. He loves his Science Diet. I don't plan on changing any time soon.
