Dog Feeding Calculator
Calculate RER, starting daily energy, treat and complete-food calories, cups per day and meal, and weekly and monthly quantities. The custom bowl visual separates complete food from treats and shows the per-meal portion.

How to use Dog Feeding Calculator
- Use an ideal body weight agreed with a veterinarian and the exact food's current calorie density.
- Choose the closest starting energy factor and enter all treat, topper, and chew calories.
- Measure portions consistently and adjust from repeated body weight, body condition, stool quality, activity, and veterinary guidance.
Calculator guide
Understanding Dog Feeding Calculator
A feeding plan should begin with ideal body weight and calorie density, not only a cup measure. This calculator estimates resting energy, applies a selected life-stage factor, reserves treat calories, and divides complete food across meals.
Calculation method
How the calculation works
Estimate resting energy from ideal body weight, apply a selected starting life-stage factor, reserve an explicit treat allowance, and convert complete-food calories to cups and per-meal portions. Estimate RER as 70 × weight^0.75, multiply by the selected energy factor, reserve the entered treat share, then divide remaining calories by the food's labeled kcal per cup.
Feeding review
Use the number as a monitored starting plan
The correct portion is the amount that supports the individual dog's health over time.
Worked situations
Practical examples
- A 20 kg ideal weight gives an RER near 662 kcal per day.
- A 1.6 factor produces a starting daily estimate near 1,059 kcal.
- A 10% treat allowance leaves 90% of calories for complete food.
Better inputs
Useful tips
- Weigh food in grams when the package provides kcal per kilogram; cups are less precise.
- Count training rewards, dental chews, table food, supplements, and flavored medication.
- Make small changes and monitor trends rather than reacting to one scale reading.
Before relying on the result
Limitations and common mistakes
- Energy factors are broad starting estimates and are not prescriptions.
- Disease, pregnancy, lactation, growth, working intensity, recovery, medications, therapeutic diets, and individual metabolism require veterinary assessment.
- Cup density and label calories can change between products or revisions.
Reference
Key terms
- Ideal body weight

- Energy factor
- Multiplier used to form a starting daily calorie estimate.
- Complete food
- Nutritionally complete diet supplying calories left after treats.
Important note
Calculated from the entered values using the displayed method. Animal health, nutrition, and medication decisions require confirmation from a qualified veterinarian.
Frequently asked questions
Why use ideal rather than current weight?
Current weight can overstate or understate energy needs when body condition is outside the target range.
Can the result be used for puppies?
A starting puppy factor is available, but growth feeding should be supervised by a veterinarian.
Why reserve treat calories?
Treats add energy and can dilute a complete diet if not counted.
Is a cup the same for every food?
No. Calorie density varies widely, so use the exact label.
