 You've heard me say it, dog food is dead food. Truth is, naturopathic Dr. Dennis Black created Rough Greens because of his love and concern for dogs. By the way, he's an amazing man. A former airborne ranger, green beret, and helicopter pilot, but now Dr. Black has a new mission, to help us do what's best for our furry family members. I am so glad he created Rough Greens to help dogs who suffer from itchings.
