Not to mention the generic label "animal fat"! Even worse, the "animal fat" is preserved with BHA/BHT - possible carcinogens. Then you have wheat mill run which is an extremely low-grade filler, wheat flour - another filler, SALT (dogs don't need that added salt in their kibble), natural poultry flavor (again, dogs really don't need this!), caramel color (dogs don't care what color their food is), etc. etc. Yuck yuck, I haven't looked at the ingredients list for Pedigree in awhile, but that's just ick.

Like it was mentioned before, it does not matter what kind of food you feed your dog provided s/he does well on it. My neighbor's cat is approaching her 17th birthday and she lives off a mix of Fancy Feast and Iams. She doesn't know that she isn't eating Felidae or Wellness. The point is that she has energy, she's healthy, and the food is working for her. That's all that matters

If you would really like to switch, I would recommend any of the following brands:
Blue Buffalo
Canidae
Wellness
Wysong
Pinnacle
Fromm
Innova/EVO (I adore Innova and EVO)
California Natural
Karma
Azmira
Flint River Ranch
Chicken Soup for the Dog Lover's Soul
Natural Balance
Solid Gold

There are plenty more but these are just off the top of my head.
ETA: To switch your dog's food, do so gradually. For the first few days, feed her 75% old food 25% new food. Gradually, wean her onto 50% old food 50% new food, 25% old food 75% new food. Soon, she'll be eating 0% old food and 100% new food.
