Dog Calorie Calculator
Estimate daily calories from weight and activity using standard RER and MER formulas. Use adult-dog multipliers unless your vet specifies a different plan.
Results
How Does This Calculate?
RER = 70 × Weight (kg)0.75
MER = RER × Activity Multiplier
Resting Energy Requirement (RER) is the base calories needed at rest.
Maintenance Energy Requirement (MER) covers normal daily activity – use your dog's true lifestyle!
Frequently Asked Questions
What’s the difference between RER and calories from food?
MER is the true target: RER × Activity. Only use RER for disabled, seriously ill, or recovering dogs.
Can I use this for puppies?
No, puppies need more. For puppies, multiply RER × 2–3 times. Check with your veterinarian.
What if my dog is overweight?
If your dog is overweight, calculate using the ideal weight, not current weight. Always consult your vet for weight loss plans.
