I’ve been feeding my dogs Super Essentials for the past two years. I have 4 rescue dogs and all my dogs have medical issues in some form due to their original pasts. In addition to raw foods, including meaty bones, I supplement with Super Essentials. The Spirulina is helpful for the arthritis and the Clay and Nettle are also good for detoxing from toxic chemicals. All ingredients are organic and non-GMO. My holistic veterinarian recommended this product, and I am forever grateful.
