helpHow to use this result?

1. Adjust Food Amount

Look at your pet food label for "kcal/kg" or "kcal/cup". Divide your DER by the food's calories to find the daily portion.

2. Monitor & Adapt

RER is a starting point. If your pet gains weight, reduce calories by 10%. If they lose weight, increase by 10%.

RER = (30 × 12.5) + 70 = 0

Factor = 0 (adult, dog, normal)

DER = 0 × 0 ≈ 0

helpFrequently Asked Questions

Why is this different from the feeding guide on my pet food bag?expand_more
Bag guidelines are broad averages. This calculator uses WSAVA veterinary formulas tailored exactly to your pet's unique age, neuter status, and activity level.
What is RER vs. DER?expand_more
RER (Resting Energy Requirement) is the baseline calories needed just to exist. DER (Daily Energy Requirement) is the total calories needed including daily activity.
Why does neutering decrease calorie needs?expand_more
Neutering/spaying alters metabolism and hormones, typically reducing total daily energy requirements by about 20-30%.
