This table is based upon a dog's Resting Energy Requirements or RER. The RER is the basic amount of energy that a dog would use in a day while remaining at rest. The formula to calculate RER for animals between 2 and 45 kg (5 - 99 pounds) is: RER in kcal/day = 30(body weight in kilograms) + 70. Any activity or variable other than rest will require an increase in energy (RER) and an increase in calories to meet the energy needs. Realize that these numbers are not a reflection of maintenance calories but of resting energy levels.
