Calcolatore di Porzioni per Cani (Calorie e Tazze)

Calcola le kcal giornaliere e la porzione in tazze/grammi per il tuo cane in base a peso, età (cucciolo/adulto/anziano), livello di attività e densità calorica del cibo. Include preimpostazioni per marca.

Come funziona il calcolo

RER (energia a riposo) = 70 × (peso corporeo in kg)^0.75. MER (fabbisogno giornaliero) = RER × moltiplicatore per fase di vita: cucciolo 2–4 mesi ×3, cucciolo 4–12 mesi ×2, adulto intero ×1.8, adulto sterilizzato ×1.6, anziano ×1.4. Cani attivi +20%, obiettivo di perdita peso ×1.0 del RER, aumento di peso ×1.6.

1 tazza standard di crocchette secche ≈ 100 g (varia tra 90–120 g in base alla dimensione delle crocchette). Per maggiore precisione, pesa sempre il cibo con una bilancia da cucina. Regola la porzione del ±10% ogni 2 settimane in base al punteggio di condizione corporea (dovresti riuscire a sentire le costole senza vederle).

Come funziona il calcolo

Daily calories start from Resting Energy Requirement, RER = 70 × (body weight in kg) raised to the 0.75 power. That is multiplied by a life-stage factor — Puppy 2–4 months ×3.0, Puppy 4–12 months ×2.0, Adult ×1.6, Senior ×1.4 — and then by an activity factor: Sedentary 0.9, Normal 1.0, Active 1.2, Very active / working 1.4. An intact adult uses 1.8 rather than 1.6. Cups are simply the resulting calories divided by the kcal-per-cup figure, and grams follow from cups.

The kcal per cup value matters more than most owners expect. At 20 kg on the defaults, moving from the generic store brand at 350 to Purina Pro Plan at 410 changes the portion by about 15 percent for exactly the same calories, so set Food to Custom and enter the number printed on your own bag. Weight goal is the other big lever: Lose weight drops intake to RER alone, while Gain weight raises the multiplier.

Grams come from a fixed assumption that one cup of dry kibble weighs 100 g, and real kibble runs roughly 90 to 120 g per cup depending on piece size — weigh one level cup on a kitchen scale and trust grams from then on. The intact adjustment applies only to the Adult stage, and Lose weight discards age and activity entirely. None of this substitutes for a body condition score or veterinary advice.

Domande frequenti

How many calories does a 20 kg dog need per day?

Resting energy is 70 times 20 to the 0.75 power, about 662 kcal. A neutered adult at normal activity multiplies that by 1.6 for roughly 1059 kcal a day, which at 370 kcal per cup works out to about 2.86 cups of food.

Why does my portion change when I switch food brands?

Because the cup figure is calories divided by calorie density. The presets run from 350 kcal per cup for a generic store brand up to 410 for Purina Pro Plan, so the same dog needs noticeably fewer cups of the denser food.

How do I feed a dog that needs to lose weight?

Selecting Lose weight sets intake to resting energy exactly, discarding the age and activity multipliers altogether. That is an aggressive target, so use it under a vet-supervised plan with regular reweighing rather than running it indefinitely on your own judgement.

Should I split the daily amount into two meals or three?

The table under the result shows two, three and four meals with kcal, cups and grams for each. Splitting does not change the daily total; it mainly affects hunger between meals, and matters most for puppies, who carry the highest multipliers here.

Is one cup of dog food really 100 grams?

That is the fixed conversion this tool uses, and it is only an average. Real kibble runs roughly 90 to 120 g per cup depending on piece size and shape, so weigh one level cup of your own food once and use the gram figure instead.
