 Dr. Marty's Nature's Blend is a premium freeze-dried raw dog food designed to support your dog's health, happiness, and lifespan. Their jaws are more flexible, their teeth are cleaner, and their coats shiner. And why they seem more useful even as they age. I'm veterinarian Dr. Marty Goldstein. I've helped countless dogs thrive with one simple concept. Your dog needs a high meat diet similar to what their ancestors ate in the wild.
