 I got a question. Is your dog a picky eater or maybe has bad breath, dull coat, low energy, or even some digestive issues? Greetings. I'm naturopathic Dr. Dennis Black, founder of Rough Greens. And for decades, I've taught humans how nutrition is critical for our optimal health. Well, the same is true for our furry family members, which is why I created Rough Greens. Because unfortunately, dog food is dead food.
