Dog Food vs. Dog Food

I've always fed my baby a Lamb and Rice dog food and been happy with it but her weight is on the upside and we've fought a battle with it for months. Today while on the phone with another DGer I looked at the Iams website and freaked at the high amount of fat the the low quality of ingredients in the food. If this is a top quality food I'd hate to see Old Roy! Look at this list and the fat content, no wonder she was turning into a little piddle.
