Premium foods also feature high quality carbohydrate sources like rice, one of the most digestible grains. Due to the nutrient density and quality of ingredients, the average premium food is more digestible than the average standard food. This results in less backyard clean up for you. Since the ingredients are of higher quality, the cost of premium foods tends to be higher on a per pound basis. However the fact that they are of higher nutrient density and digestibility means the amount of food fed is less, so while overall feeding costs are higher it's not as much as you may think.
Some people leave food out all day long for their dog.
Dry pet food can be left out all day as long as your dog does not overeat and gain excessive weight. Even when given food all day, most dogs will generally only eat once or twice a day. However, if your pet gains too much weight, it's a good idea to feed your dog using discrete meals once or twice a day. Once your dog adjusts to a particular food, the dog's system, including the bacteria that live in the gastrointestinal, establish a careful balance. Because different foods contain different ingredients and nutrients, too quick a change can upset his system.
