How many days will my dog food last?
Add different daily portions for each dog to estimate when the remaining dry food runs out and when to reorder.
Formula and assumptions
The result is stock duration if each dog's current amount continues. For ordering, subtract delivery lead time from the earlier high-use run-out date.
Why the result can vary
Growth, activity, weight-management changes, switching food, treat share, scoop error, and spills alter the rate stock falls.
Example
Order food for two dogs
Inputs: 10kg food, first dog 300g/day, second dog 200g/day
Outcome: At 500g total a day, that is about 20 days before accounting for waste.
Cautions
- This calculator does not prescribe an appropriate portion or weight-management plan.
- Use product guidance and the dog's health needs; consult a veterinarian when changing a feeding plan.

Frequently asked questions
Can the dogs have different serving sizes?
Yes. Enter daily grams separately for each dog and the calculator uses their sum.
Will it recommend a portion from body weight alone?
No. Calorie density and each dog's needs differ, so it does not invent a serving. Enter an amount from the label or veterinarian.
Can I use this for wet dog food?
The duration formula works when stock and daily use share a mass unit, but opened-product storage limits must be checked separately.
