The only fluid your dog needs is water, and that's all. And I support what everyone else has mentioned about Pedigree...I myself used to feed this food, and while nothing really awful resulted from it, my dogs have done SOOOO much better on Canidae. They have nicer coats and skin, have lost some a lot of unnecessary weight, and therefore have a lot more energy. It's an excellent food, and you'll find that your dog will eat quite a bit less, as it's more nutrient dense, so the cost will definitely balance out over time. I swear by it, and also treat them with the Canidae All Life Stages canned food a couple nights a week for a bit of variety.
