You'd be hard pressed to find a worse brand to pair with your raw diet than pedigree. Awful awful stuff. If you're going to fill gaps with kibble, I'd suggest picking something like Blue Buffalo Wilderness. Raw diets (done correctly, as a veterinary assistant I see them done incorrectly a lot) are a top quality source of food for your buddy, it allows you to control potential allergens and helps body condition to be more fluid. Pedigree is basically $1/lb for everything any dog has ever been found to be allergic to, plus a ton of extra filler that makes it harder for your dog to maintain good body condition.
When I moved in with boyfriend, he was feeding his husky a Purina product, and when I got my GSD mix puppy we switched her onto Taste of the Wild Salmon formula (a compromise, he didn't want to "go crazy" with an expensive food) because I refused to feed my boy that garbage. Within a week of the final switch we could tell a huge difference with her coat. I had considered going to raw, but my boss is pretty generally against it because of how commonly people screw it up, I'd never hear the end of it if I had to bring one of my dogs in for a problem she thought could be related.
