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.
Be calorie smart 400-600-600. Calories are a measure of the amount of energy in food and drinks. Knowing how many calories are in your food can help you balance the energy you put in your body with the energy you use, which is the key to maintaining a healthy weight. The calorie rule of thumb is simple! 1  Just eat around 400 kilocalories (kcal) for breakfast (including any drinks and accompaniments) 2  600kcal for lunch (including any drinks and accompaniments) and another.  600kcal for your evening meal (including any drinks and accompaniments)
