Dr. Tim's Pet Food Company offers All Life Stages grain-free dog food, a complete meal for dogs with sensitivity to grain-based carbohydrates. The product is based primarily on the animal proteins pork meal and salmon meal, which are rich in proteins, vitamins and omega 3 fatty acids. Dr. Tim's slow cook method produces a kibble that is extremely digestible, highly palatable and affordable, according to the company. Prebiotics, externally applied probiotics and natural antioxidants help promote a strong immune system. To minimize allergic reactions, the grain-free formula features a carbohydrate blend of tapioca, peas and white potatoes.
