Our cocker spaniel is now nearly 10 years old, and the solid gold food I'd been feeding him suddenly changed its formulation over a year ago(with no notice on the packaging), and he became subject to unexplained stomach upsets. After the contaminated food scare even tho Solid Gold was not recalled, I decided to switch, and this formulation is perfect for him to not gain too much weight. Newman's own is a brand I totally trust and have bought snacks for my human baby as well for years. After a year on this food, my dog is doing fine, but I do notice a need to supplement with fish oil for a healthier coat. That may be age related as well. But the stomach upsets have stopped. And I feel better knowing I am not exposing him to additional pesticides and hormones by going mostly organic with this formula.

Nothing easier. Nothing better. Even beats grandmother's white gravy recipe. Already peppered for you. You do nothing but mix it with water. Takes only a minute or two. I highly recommend this gravy mix. It will not disappoint.
