 Healthy my dogs are. One of the reasons is the food my dogs eat. 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 joints are more flexible, their teeth are cleaner, and their coat shinier. And why they seem more youthful 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.
