How much to feed
How much should I feed a 70kg dog?
Last updated 23 September 2026 · How we write and check this
Short answer
A 70kg dog, an exceptionally large giant breed, typically needs about 700 to 725g of a standard dry food a day, almost always split into two or three meals. At this size, a kitchen scale that reads accurately in large gram amounts and a food storage plan that keeps a big bag fresh for several weeks both matter more than they do for any smaller dog.
The calculation
Resting energy for a 70kg dog is around 1,693 kcal, and a typical neutered adult at normal activity needs close to 1.6 times that, about 2,710 kcal a day. At 350 to 400 kcal per 100g of dry food, that comes to roughly 700 to 725g a day.
That is over 21kg of food a month, a genuinely large ongoing cost and volume to plan for.
Why this weight needs its own plan
Many household scales are not accurate or even usable much past 5kg per reading, so weighing out a 240g meal is fine but tracking your dog's own body weight monthly usually means using your vet clinic's scale instead.
A vet familiar with giant breeds is worth involving early to confirm the calculated amount suits your specific dog, since individual variation at this extreme size can be larger than the general formula accounts for.
Feeding practicalities
Split the daily total into at least two meals, and consider three if your dog seems more comfortable with smaller amounts at a time.
Store food in a sealed, airtight container and buy in a quantity you can realistically use within a few weeks, since freshness matters for both taste and consistent calorie content. Keep the storage bin somewhere cool and out of direct sunlight, which helps preserve quality for the full length of a large bag.
Key takeaways
- A 70kg giant breed dog typically needs about 700 to 725g of dry food a day.
- This is over 21kg of food a month, worth budgeting and storing for deliberately.
- Use a vet clinic scale for body weight tracking if a home scale is not accurate at this size.
- Split food into at least two meals and involve your vet in confirming the amount.
