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.
The resting metabolic rate (RMR) is the number of calories the body requires at rest. It is important because any calorie intake above this resting metabolic rate (RMR) is stored as fat by your body.The RMR is a good estimate for those of us without access to complex laboratory testing of oxygen consumption and carbon dioxide gas production. The basic formula for estimating RMR at rest is:our resting metabolic rate is approximately one kcal per kilogram of body weight per hour. (To find your weight in kilograms, divide your weight in pounds by 2.2.) If you weigh 132 pounds, or 60 kilograms, you will burn 60 kcal an hour.
