Is a bigger bag of dog food always better value?

Not automatically. A larger bag often has a lower price per kilogram, but only if you can store and use it before it goes stale, and only if the per-kilogram figure is actually lower once you check rather than assume. Compare the real cost per kilogram rather than the headline price.

How can I compare dog food prices fairly?

Divide the total price by the pack weight to get a cost per kilogram (or cost per 100g for wet food), and compare that figure across products rather than comparing headline prices, which can be misleading between different pack sizes and calorie densities.

Where can I see your delivery costs?

Our current delivery charges and any free-delivery threshold are shown clearly at checkout before you confirm your order, so you can see the full total including delivery rather than discovering it afterwards.

Does a cheaper dog food mean lower quality?

Not necessarily — price reflects ingredients, formulation and brand positioning rather than a single quality scale. What matters more is whether the food is complete, suits your dog's life stage, and agrees with them, which price alone won't tell you.

Dog food with free delivery

Delivery cost is worth checking, but it is only one part of what a bag of dog food actually costs you — the price per kilogram, or per portion for wet food, tells you far more about real value than the delivery line alone. Our current delivery charges and any free-delivery threshold are shown clearly at checkout before you pay, rather than buried in the small print.

Why price per kilogram matters more than the sticker price

A cheaper bag is not automatically better value if it is also a smaller bag, or if your dog needs to eat more of it to get the same nutrition as a more calorie-dense food. Dividing the total price by the pack weight, and comparing that figure across brands, gives a much fairer picture than comparing headline prices alone.

The same logic applies to wet food: comparing cost per pouch ignores that pouches vary in size and in how much of a dog's daily needs one pouch actually covers. Cost per 100g, or cost per typical daily portion for your dog's weight, is the more honest comparison.

How delivery actually factors in

A heavier bag of dog food costs more to deliver than a lighter one, which is part of why larger sacks are not always proportionally cheaper once delivery is accounted for. It is worth checking the full basket total, including delivery, rather than just comparing product prices in isolation.

Our delivery costs and any current threshold are set out clearly at checkout, so you can see the full total before confirming an order rather than discovering it at the end. We would rather show that plainly than lead with a headline that does not reflect what you will actually pay.

Buying sensibly for your dog and your freezer or cupboard

Buying a larger bag can bring the per-kilogram cost down, but only if you can store it properly and use it within a reasonable time — dry food loses freshness once a bag has been open a while, so a huge saving on paper is not worth it if a third of the bag goes stale.

For most households, matching pack size roughly to how much your dog eats in four to six weeks strikes a reasonable balance between value and freshness, whatever the delivery terms on any individual order happen to be.
