Dog Calorie Calculator

Estimate daily dog calorie needs with RER = 70×kg^0.75 and educational MER life-stage factors—planning math, not a medical diet order.

RER + MER

How to Use the Dog Calorie Calculator

Enter the fields below, then review the educational estimate.

1

Enter weight and unit.

Body condition matters

Two dogs of equal weight can need different calories. Ideal weight and BCS scoring belong with your veterinarian.

What This Calculator Estimates

Returns RER, the selected MER factor, and maintenance kcal/day for educational planning.

Worked Examples

10 kg neutered adult

Inputs

weight:10
weightUnit:kg
lifeStage:neutered_adult

Result

629.8 kcal/day MER (RER 393.6)

70×10^0.75 ≈ 393.6; ×1.6 ≈ 629.8.

When to call a veterinarian

Appetite changes, rapid weight shifts, lethargy, vomiting, or suspected toxin exposure need professional care—not another calculator.

Frequently Asked Questions

Formulas & Assumptions

Transparent educational arithmetic. Not a veterinary exam, diet prescription, or toxicity tool.

Metric:RER ​=​ 70​×​kg0<​/​sup>.75; MER ​=​ RER​×​factor

Formula

RER ​=​ 70​×​kg0<​/​sup>.75; MER ​=​ RER​×​factor

Scientific Background

Allometric RER equations and MER multipliers appear throughout companion-animal nutrition education. They are starting points, not individualized prescriptions.

Sources & review

Dog Calorie Calculator documents the references behind its formulas and assumptions. Always treat results as educational estimates, not personalized professional advice.
