Pedigree sucks, unless you want to feed your dog the nasty parts of an animal that no one else will use, like the bits and pieces with cancer and tumors and infection. It's made of pure filler - not good for dogs, but cheap.
Any of the affordable brands that you can buy in the grocery store are awful, filled with nasty fillers, and nothing that a dog would eat naturally. Although Purina has surprised me with their Beyond® label - meat and vegetables with no grain or fillers! I'm impressed that they have jumped on the natural feeding bandwagon! Bravo!
On the Drools website, you really have to hunt for an ingredients list which is not a good sign, but I think it's a "natural" product with no fillers, with chicken advertised as the first main ingredient in the adult dry dog food.
The best dog food to feed your dog is the most expensive natural meat based diet without grain that you can afford. You will save a heck of a lot of money in the long run on vet bills such as teeth cleaning, parasite control and more serious issues. Dogs' digestive systems are not designed to ingest grains as a main diet. That's why you see so many "natural" dog foods on the market these days, with the mass market producers like Purina getting with the program and producing meat based grain free diets. They want to compete in the marketplace that is producing dog food according to the latest research! Meat based and grain and filler free!
So, do the best that you can, which may involve a little research in the beginning (like you're doing with this excellent question!), and you will have a healthy dog that will be your partner for many healthy years!
I wish you (and your wallet) the best of luck!
