Review on Diamond Naturals Premium Large Breed Formulas: Real Meat Protein, Superfoods, Probiotics & Antioxidants for Adult Dogs and Puppies by Becky Burnett

I have a 7 year old Great Dane who was raised on Diamond Natural Food. It is a high quality food that provides good nutrition. My vet always talks about how fit and healthy he is for a giant dog. I always fed him for free which allowed him to consume his 8 cups of food throughout the day rather than in one sitting. He is still cheerful and full of energy despite having reached retirement age. He's never had digestive issues and I feel good about giving him a product without useless fillers. Edit 5/2021: My mastiff has eaten this food all his life. We just had to put him down last month. He was 10 years old. Joint pains drove him to the end. The vet said he was in excellent health aside from severe arthritis. I attribute that to his diet. I firmly believe in the quality of this food brand.
