The amount is calculated with the RER formula and the multipliers used in veterinary practice: weight, age, neutering and activity level. Enter your food's calorie content to get grams, not just calories.

Calculation
kg
Growing and senior animals are calculated differently.
5 is ideal. Ribs can be felt but not seen, and the waist is visible from above.
Activity
What we do with the weight
What you feed
Kibble. Usually around 3600 kcal per kilogram — the exact figure is on the bag.
Dry food is usually 3,300–4,500 kcal per kg. If the bag gives it per 100 g, multiply by 10: 380 kcal per 100 g is 3,800.
Grams of food per day267g
Per meal134 g133 g
Calories per day960 kcal
Of that, for treats96 kcal
No date of birth on file — calculated as an adult animal.
No more than a tenth of the daily allowance. A treat is balanced for pleasure, not for need, and a larger share skews the diet even when the calories add up. This is where weight is usually gained: the food is weighed, the biscuits are not.
What it costs
Switching to another food?
An abrupt switch is the most common cause of diarrhoea in a healthy animal. The new food usually gets the blame, though the speed is at fault. The daily total stays the same — only the proportions change.
