Just as you require a proper, well balanced diet to stay fit and healthy, so does your dog. In order to stay healthy and function well, your dog requires an appropriate amount of protein, carbohydrates, fats, vitamins, minerals and water every day. The pet food manufacturers make sure to produce all such dietary products that provide everything your dog requires daily. They create food products to cater the nutritional need of puppies, adult or older dogs. They also design food products to control specific health conditions that a dog may suffer with.
