Dr. Tim's Premium All Natural Pet Food lines have been formulated as a complete wholesome meal for your pet. Leveraging the science and knowledge we gained from working with sled dogs like Dallas Seavey’s winning Iditarod team, we’ve developed diets that benefit all pets, regardless of their activity level. Our formulas are made up of the highest quality, low ash protein ingredients, along with the right blend of carbohydrates, fats and fibers allow your animal to lead a hale and hearty life. Our slow cook method produces a kibble that is extremely digestible, highly palatable and affordable. Externally applied probiotics, prebiotics and natural antioxidants help keep your pet's immune system strong. To minimize allergic reaction, corn and soy products are not used in Dr. Tim's Premium All Natural pet food products.These pet foods have been formulated through the combined efforts of a Ph.D. canine nutritionist and a veterinarian experienced in athletic and competitive dog sports.
