⚡ Daily Energy Requirement (DER)
Input your dog's weight and lifestyle details below to compute their target daily kcal budget.
Understanding Your Dog's Caloric Intake
A dog's daily calorie requirement is not a one-size-fits-all metric. It is built upon their Resting Energy Requirement (RER)—the energy needed to perform basic life functions such as breathing and cell maintenance—multiplied by an activity factor representing their metabolic demand.
Our calculator implements the industry-standard metabolic formulas endorsed by the Waltham Centre for Pet Nutrition and the National Research Council (NRC):
RER (kcal/day) = 70 × (Weight in kg)^0.75
Factors such as age, neutering status, and activity levels scale this RER up or down. For example, a working border collie has higher muscular exertion requiring an activity multiplier of 2.5, whereas an aging senior dog with lower muscle mass utilizes a multiplier of 1.4.
