How Much Dog Food Does Your Dog Need Per Month?
Knowing how much your dog eats in a month helps you pick the right bag size, compare the real cost of each food and reorder before you run out. These are estimates for a healthy adult dog with normal activity. The feeding table on your bag always comes first.
Quick answer
- A 10kg dog eats about 5kg of dry food a month.
- A 20kg dog eats about 8.5kg a month.
- A 30kg dog eats about 11.5kg a month.
- A 40kg dog eats about 14.5kg a month, close to one 15kg bag.
Monthly dry food by dog weight
| Dog weight | Per day | Per 30 days | A 15kg bag lasts |
|---|---|---|---|
| 5kg | about 100g | about 3kg | about 5 months |
| 10kg | about 170g | about 5kg | about 3 months |
| 20kg | about 290g | about 8.5kg | about 7–8 weeks |
| 30kg | about 390g | about 11.5kg | about 5–6 weeks |
| 40kg | about 480g | about 14.5kg | about 4 weeks |
These figures use a standard estimate of daily energy needs for a neutered adult dog and a food with about 3,700 kcal per kg. Foods with more or fewer calories change the amount, so a richer food can last longer than a cheaper one. Small dogs do better with a smaller bag, because an opened bag is best used within about six weeks.
What changes the amount
- Activity: working and very active dogs need more, while quiet indoor dogs often need less.
- Body condition: if your dog is gaining weight, ask your vet before cutting food sharply.
- Age: puppies, seniors, pregnant and nursing dogs have different needs, so this table does not apply to them.
- Treats: keep treats under about 10% of daily food.

Monthly cost multiplies today’s price per kg by 8.5kg, so it changes with prices and sales. It is a comparison, not an exact bill.
How to weigh a daily portion
Weigh one day of food once on a kitchen scale, then mark that level on a cup. Split it into two meals. Change foods over about 7 days, and always leave fresh water out.
Questions
How much should a 20kg dog eat per day?
About 290g of dry food a day for a healthy adult dog, or about 8.5kg a month. Check the feeding table on your bag, since calories differ between foods.
How long does a 15kg bag of dog food last?
About 7–8 weeks for a 20kg dog and about 4 weeks for a 40kg dog.
Is a bigger bag cheaper?
Usually the price per kg is lower on bigger bags, but compare the price per kg for your food. Heat and humidity also matter: keep opened food cool and dry, and use an opened large bag within about six weeks.
Does this work for puppies?
No. Puppies need a puppy food and the amount on its feeding table, based on age and expected adult weight.
How fast do you deliver dog food?
Orders inside Beirut arrive the next day, and orders outside Beirut take 2-3 days. You pay cash on delivery.
