How Many Calories Does My Dog Need?
Your dog’s daily calorie requirement is calculated using the veterinary RER (Resting Energy Requirement) formula: 70 xd7 (body weight in kg)^0.75, then multiplied by a life stage factor to get the MER (Maintenance Energy Requirement). Our dog calorie calculator does this instantly.
