Why is the feeding chart on the specific bag of food essential, given variations in food type?

Answer

It is calibrated for that product's specific energy content (kcal)

Not all commercial dog foods provide the same energy density, even when measured using the same volume, such as one cup. Calorie density varies substantially between different preparations, including dry kibble from various brands, wet food formulations, and raw diets. Because of this inherent variability, the kilocalories (kcal) per unit of measurement differ greatly. Therefore, the feeding chart printed directly on the specific package of food being used is vital because that chart has been calculated precisely according to the energy content of that particular product, making it the most accurate guideline for that specific food item.
