Outstanding. We recently purchased two Italian Greyhounds last summer, they are still puppies. Having heard about Ruff Greens as one of the sponsors I regularly listen to I purchased some right away. However, the dogs were young and small and I was unsure about how much to give them daily. I called customer service and was immediately connected with an ACTUAL PERSON who answered all my questions. My dogs won't eat food without it. They are strong, active, and their coats look amazing! Great product and excellent customer service. It's a product we will continue to use for their lifetime.
