Buying dog food in bigger bags
We sell to pet owners, not trade — there's no separate account or minimum order here, just the same bags any customer can buy. Buying a bigger bag is still the most reliable way to bring the price per kilo down, though we won't pretend one shop undercuts every other on every recipe. A 14kg or 15kg sack works out cheaper per kilo than the same food in a 2kg bag almost every time, which matters most if you've got a large dog, more than one dog, or you'd simply rather not be back on the site every fortnight.
Why the bigger bag is usually the better price
A bag of dog food costs money to print, seal and box up whatever size it is, and that cost is spread over fewer kilos in a small bag than a large one. That's the whole reason a 15kg sack of the same recipe almost always beats a 2kg bag on price per kilo — you're paying for less packaging relative to the food inside it.
It isn't automatic, though. Some brands price their smaller bags as an introductory size and their mid-size bags as the real value option, so the very biggest bag on the shelf isn't always the cheapest per kilo of everything that brand makes. Dividing the price by the weight on any two sizes of the same recipe takes seconds and tells you straight away which is genuinely better value for how you actually feed.
How far a big sack actually goes
A large adult dog gets through a bag of dry food a great deal faster than a small one, and a multi-dog household faster still — that's the sensible reason to buy a 14kg or 15kg sack rather than replacing a 2kg bag every week or two. The feeding guide printed on the bag is the right place to work out roughly how long a given size will last your dog, since it's written for that specific recipe rather than dog food in general.
The other side of the sum is freshness: a sack that sits half-full for months because it was bought too big for one small dog isn't actually a saving. If you're feeding a single small or medium dog, a mid-size bag that gets finished within a few weeks is often the more sensible buy than the largest sack on the shelf, even at a slightly worse price per kilo.
Which of our dry food ranges come in a big bag
We carry a good number of complete dry dog foods in 14kg and 15kg sizes, including ranges like James Wellbeloved, Skinner's Field & Trial, Chappie, Burns and Harringtons, alongside several own-brand and working-dog lines built specifically around bigger bags for households that get through food quickly. Puppy and senior recipes are generally sold in smaller sizes, since the dogs eating them tend to need less food or grow out of a bag before it becomes the better buy.
Not every recipe on the site comes in every size — some smaller-batch and grain-free foods top out at 12kg or less. The size options for a given food are shown on its own product page, so it's worth checking there rather than assuming every bag scales the same way.
Comparing price per kilo across sizes
The only reliable way to compare value is price divided by weight, done on the exact same recipe rather than across different foods. A 15kg sack at one price and a 2kg bag of the same recipe at another will usually show a clear gap once you do that sum, and it's worth doing it on the product page rather than trusting that bigger always wins.
It's also worth comparing across brands at the size you actually need rather than chasing the single cheapest bag in the whole range — a 15kg sack of a food your dog won't eat happily isn't good value at any price. Match the size to what your dog actually gets through, then compare price per kilo within that shortlist.

Common questions
- Is the biggest bag of dog food always the best value?
- Usually, but not always. Some brands price a mid-size bag as their real value option rather than the largest one, so it's worth dividing the price by the weight on a couple of sizes of the same recipe before assuming the biggest sack wins on price per kilo.
- How should I store an opened sack of dog food?
- Keep it somewhere cool and dry, fold or clip the top down tightly between uses, and consider decanting it into an airtight container if the bag itself doesn't reseal well. Kibble left open to the air loses its smell and appeal to a dog faster than most owners expect.
- Will a 15kg bag go stale before my dog finishes it?
- It can, if you've got a single small dog eating a modest amount each day. A big bag is better value on paper for a large or multi-dog household that gets through it within a few weeks; for a small dog on their own, a mid-size bag that's finished sooner is often the more sensible buy.
- Can I switch straight from a small bag to a bigger one of the same food?
- Yes, as long as it's genuinely the same recipe — the size of the bag doesn't change what's in it. If you're changing recipe at the same time, introduce the new food gradually over several days rather than swapping the whole bowl over in one go.
- Can I buy dog food from Giddy Pets in bulk?
- Yes — the bigger bags on the site are simply the largest size each brand makes, priced and sold the same way to every customer. We're a retail shop for pet owners rather than a business account setup, so there's no separate pricing tier or minimum order to unlock a bigger bag.
