Dr. Tim's Metabolite Weight Management Formula uses a novel approach to taking weight off your dog by rethinking the process and turning it into a win/win lifestyle for your pet AND you. Our high levels of protein, complimentary fiber structure and moderate fat content work in tandem with your pet's natural metabolism to support weight loss. Our formula acts as a lock and key, opening one metabolic route after another to ensure your dog is optimizing their natural ability to burn calories, and also ensures you won't give up due to excessive begging. Metabolite incorporates all angles of the weight loss process, from the molecular structure of the ingredients to the psychology of the pet owner, to build and maintain your dog's healthy weight while understanding the behavioral difficulties of an overweight dog who's always hungry. Metabolite is made without corn, wheat or soy for the sensitive dog. Metabolite Weight Management Dog Food has been formulated through the combined efforts of a Ph.D. canine nutritionist and a practicing small animal veterinarian experienced in competitive dog sports.
