Corn is the main ingredient in Pedigree foods. It made my dog's poop very soft and soggy and light-colored. It also made his eyes form eye-boogers every day. I have since switched to another brand that does not have corn in it, and his poop is now a healthy, solid, darker-colored poop. And his eyes do not produce nearly as many eye-boogers. I am very disappointed in my experience with Pedigree. I don't like that they try to pass their product off as natural and healthy for dogs, when a lot of dogs are sensitive to that much corn in their food. Heck, a lot of people would sensitive that much corn product in their food.
