Dog-years age done honestly, daily food portions, puppy schedules, exercise needs, vet-cost budgets, insurance maths and warm practical guides — ask a dog question and get a straight, careful answer in seconds. The full detailed report costs less than a cup of coffee: $2.95.
Feeding by guesswork is how dogs end up overweight — and most pet dogs are. This calculator starts from the standard veterinary formula: resting energy needs of about 70 × weight in kg to the power 0.75, multiplied by a life-stage factor (roughly 2.1× for growing puppies, 1.35× for seniors, and 1.0-2.0× for adults depending on activity). You enter your dog's weight, pick a life stage and rate daily activity, and get a daily calorie figure, the equivalent grams of a typical dry food, and cups — all split into the right number of meals. The verdicts keep it honest: this is a starting point, body condition is the real test, and puppies and seniors get their own specific guidance.
Estimate your dog's daily calories and dry-food portion from body weight, life stage and activity — a science-based starting point (resting energy needs) you then adjust to body condition.
Start from the resting energy formula — about 70 × (weight in kg)^0.75 — then multiply by life stage: growing puppies roughly 2.1×, adults 1.0-2.0× depending on activity, seniors about 1.35×. The calculator does this for you and converts the result into grams of typical dry food.
Grams. A 'cup' of one kibble can differ from another by 30-40% in calories because kibble density varies by brand and recipe. Weighing the daily portion on a kitchen scale is the single most accurate feeding habit you can adopt.
Cut the daily portion by 10-15% and re-check body condition after two weeks: ribs should be easy to feel under a thin layer, with a visible waist from above. Also count treats — if they exceed about 10% of daily calories, meals need to shrink to match. If weight changes are sudden or unexplained, ask your vet.
Every tool answers instantly from our own knowledge and calculators — no AI wait, no account. Honest estimates built on widely used dog-care rules of thumb, always warm, practical and educational — never a substitute for your vet. If your dog is unwell, injured or behaving oddly, ask a vet: we signpost, we never diagnose. Want the deeper, personalised version? Each has a $2.95 full report.
