3. Factor in an 'Appropriate Multiplier'
Appropriate multipliers include such things as whether or not the pet is neutered or intact, whether the pet requires weight gain or weight loss, and a variety of other factors. For example, a 10kg (22lb) adult neutered dog of healthy weight needs RER = 70(10kg)3/4 ≈ 400 kcal/day. You then multiply 400 times 1.6 (the appropriate multiplier for a neutered pet), which equals 640 kcal/day, or the MER. However, this calorie count should only be viewed as an estimate. Your veterinarian will use this information as a piece of the puzzle; also taking into account a pet’s lifestyle, age, activity level, etc.
