Hi Anthony
Dog food is made up of protein, fat, and carbohydrates. If you lower protein, then fat and/or carbs must go up. Usually, fat level is tied to protein level, so if protein goes down, so does fat. It’s carbs that usually go up. Dogs don’t need carbs and you have to feed more of them to make up for the fact that fat has double the calories. That is a lose/lose for dogs that were made to feed off of fresh protein.
