Have a look at your bag of dog food, and find the nutrition analysis. It will give you a figure for metabolisable energy, expressed in kilojoules or calories. Some ingredients, such as fiber, do add to the energy content of the food, but it’s not easy for your dog to digest. This means that it’s not readily available for your dog. Metabolisable energy is the amount of energy in your dog’s food that he can actually use. Dogs who run need more metabolisable energy than a sedentary dog.
