Bringing Veterinary-Grade Precision to Every Puppy’s Bowl.
We built Puppy Feeding Calculator (puppyfeedingcalculator.com) to solve one of the most stressful questions every new dog owner faces: “How much should I actually feed my puppy today?”
Why Generic Dog Food Bag Charts Fall Short
Most commercial puppy food bags print broad, one-size-fits-all feeding tables with wide weight brackets (such as “5 to 10 kg: feed 110g – 240g”). For a growing puppy, a 100-gram daily error can quickly lead to rapid overweight gain, digestive upset, or—in large and giant breeds—excessive skeletal stress and Developmental Orthopedic Disease (DOD).
Even worse, standard bag charts rarely account for mixed wet-and-dry feeding, training treat deductions, spay/neuter metabolic shifts, or the difference in energy density (kcal/100g) between brands like Royal Canin, Purina Pro Plan, Harringtons (UK), The Farmer’s Dog, or raw BARF diets.
Metabolic Scaling Formula
Every calculation starts with the peer-reviewed Resting Energy Requirement equation RER = 70 × (Wt_kg)^0.75 and life-stage Daily Energy Requirement (DER) multipliers.
Global Metric & Imperial
Whether you weigh kibble in grams (`g`/`kg`) in the UK and Europe or measure in `lbs`, `oz`, and standard 8-fl-oz cups in the US, our workbench converts every ration in real time.
Zero Paywalls or Sign-Ups
Your puppy’s saved profiles and weekly weight logs stay privately in your browser’s local storage—no account registration, email walls, or subscriptions required.
