How Much to Feed Your Dog Calculator
Estimate daily calorie needs and cup-equivalents based on your dog's weight, age, and activity level.
Estimates use the RER × DER formula (70 × kg0.75) used by veterinary nutritionists. Adjust by ±10% based on body-condition score. Consult your vet for dogs with health conditions, pregnancy, or lactation.
Frequently asked questions
Are these calorie estimates accurate?
They use the standard veterinary formula (RER × DER, where RER = 70 × kg0.75). The result is a starting point — actual needs vary by metabolism and body condition. Adjust portions up or down by 10% based on weight changes over 2-3 weeks.
How many meals per day should I feed my dog?
Puppies under 6 months: 3-4 small meals. Puppies 6-12 months: 3 meals. Adults: 2 meals (morning and evening). Seniors: 2-3 smaller meals. Free-feeding is generally not recommended because it makes portion control and weight monitoring harder.
What if my food's calorie count isn't on the bag?
Look up the food brand + formula on the manufacturer's website — they're required to publish kcal/cup or kcal/kg. Most dry kibble runs 300-450 kcal/cup. Don't guess — even 50 kcal off per day adds up to significant weight changes over weeks.
