This information is published by the National Research Council of the National Academies (NRC) or the Association of American Feed constipation Control Officials (AAFCIO). These councils publish everything you need to know when it comes to proper dog nutritional requirements, including the protein, carbohydrate, fat mineral, vitamin, and water needs of your dog.
Proper nutrition for your dog requires keeping the amount of protein in your dog's diet between 21% and 26%, as this is the proper percentage and the variation in the percentage should be weighed against whether you have a low-active, light, or active dog. The protein will also help your dog develop his bones, blood, and muscles more efficiently, so the protein level is very important.
Feeding your dog the proper amount of protein may be expensive, however; it is important for the dog to maintain proper nutrition. If you want your dog to get the best source of protein, make sure that the protein is of high quality.
