Kibble, Raw or Freeze-Dried? How the Three Formats Actually Differ

Extrusion, a cold chain and a vacuum chamber produce three very different bowls of food. Here is what each process does to cost, shelf life and handling — and why most customers end up feeding two of them at once.

We stock all three, which means we have no reason to sell you one. That is the whole basis of this article. A brand that only makes kibble will tell you raw is a hygiene problem. A raw company will tell you extrusion cooks the life out of everything. Both are arguing their inventory. Ours has kibble, frozen raw and freeze-dried sitting in the same room, so the honest answer is that they are different manufacturing processes with different trade-offs, and the right one depends on your freezer, your budget and how much handling you are willing to do.

Here is what actually separates them.

Kibble: cooked under heat and pressure, then dried

Kibble is made by extrusion. The ingredients are ground into a dough, pushed through a machine under high heat and pressure, and forced out through a die — that is where the shapes come from. The pressure drop at the die makes the pieces puff, then they are dried and usually sprayed with fat and palatants on the outside, because the cooking itself strips a lot of the aroma a dog is looking for.

That process is why kibble does what it does. It is shelf-stable at room temperature for months, it is cheap to ship because most of the water is gone, it needs no thawing, and it can be measured with a cup. Cooking also handles pathogens on the way through.

The cost is that heat is not selective. Some heat-sensitive nutrients degrade during extrusion, which is why brands add them back in after cooking. Baked foods like Carna4 Duck take a slower, lower-temperature route to the same shelf-stable end point, and they sit on the same dry food shelf as the extruded bags. Neither is a scandal — it is just what happens when you cook something twice at industrial scale.

Extruded kibble is dried to roughly ten percent moisture, which is what makes a bag last months in a cupboard.

Frozen raw: never cooked, so the cold chain does the work

Raw food is ground, portioned and frozen, and it has to stay frozen from the plant to the freezer case to your car to your kitchen. Nothing was cooked, so temperature is the only thing holding it stable. That single fact drives every practical difference.

You need freezer space — a real amount of it, since raw is mostly water by weight and you are buying and storing that water. You need to thaw in the fridge rather than on the counter, and feed within a couple of days once thawed. You wash the bowl, the utensil and your hands the same way you would after handling raw chicken for yourself, and you do not leave a portion sitting out.

What people feeding raw are after is food that has not been through a cooking step at all. Our raw and frozen freezer runs a bit over a hundred products, from full meals like Primal Dog Raw Pork to smaller topper formats.

The part we will not spin

Raw feeding is genuinely debated, and we would rather say so than pretend the argument is settled. Public-health bodies have raised concerns about bacterial handling with raw pet diets — for the people in the household as much as the dog, since raw food and anything it touches can carry bacteria around a kitchen. If anyone in your home is immunocompromised, undergoing treatment, elderly or a very young child, talk it through with your veterinarian before you start. That is a real conversation to have with a clinician, not a shop.

We are not going to tell you raw is superior, and we are not going to tell you it is dangerous. We will tell you it demands more of you than a scoop from a bag, and that plenty of our customers do it carefully and happily for years.

Freeze-dried and dehydrated are not the same thing

These two get used interchangeably on shelf talkers and they are different processes.

Freeze-drying freezes the food first, then pulls it under vacuum so the ice turns straight to vapour without ever becoming liquid. No meaningful heat is involved. The structure stays largely intact, which is why a freeze-dried nugget holds its shape, crumbles dry, and rehydrates back toward something like its original texture when you add water.

Dehydrating and air-drying use gentle warm airflow over hours to evaporate the moisture out. There is heat, just far less of it than extrusion, and the result is denser and chewier rather than crumbly — think of the difference between a freeze-dried strawberry and a dried apricot. Zeal Air-Dried Salmon & Duck sits on the air-dried side; a bag of Pure Protein Dried Sardines is dehydrated whole fish and nothing else.

Both routes remove water, so both are shelf-stable and light. Freeze-drying is the more expensive process to run, which is a large part of why freeze-dried food carries the highest price per calorie of anything in the store. You are also paying for the water you removed and will add back at home. What you get for it is a food you can keep in a cupboard, throw in a bag for a weekend, and feed on a plane trip or at a cabin with no freezer.

The three side by side

Format How it is made Storage Handling Relative cost per feeding
Kibble Extruded under heat and pressure, then dried Cupboard, months Scoop and go Lowest
Frozen raw Ground and frozen, never cooked Freezer, thaw in fridge Wash hands, bowls and surfaces; do not leave out Middle to high
Freeze-dried Frozen, then water removed under vacuum Cupboard, months Feed dry or rehydrate Highest
Air-dried / dehydrated Gentle warm airflow over hours Cupboard, months Feed as is Middle to high

What most people actually end up doing

Almost nobody who walks in asking this question leaves feeding one format exclusively. The common landing spot is kibble as the base with a topper on top — a scoop of raw or a crumbled freeze-dried nugget stirred through the bowl.

It works because it splits the trade-off. The base keeps the cost per feeding and the convenience roughly where kibble puts them. The topper adds smell and texture, which is usually what a bored eater is actually responding to, and it lets you try raw with two square feet of freezer instead of a whole shelf. Toppers are also the cheapest way to find out whether your dog even likes raw before you commit to a month of it.

Practical notes if you go this way: a topper is food, not a garnish, so take the calories off the kibble side rather than adding them on top. Introduce it over several days like any diet change. And if you are adding frozen raw, the handling rules still apply to the small amount — same hands, same bowl, same fridge.

Our dehydrated and freeze-dried shelf is close to three hundred items, which is more useful for this than it sounds: most of it doubles as a topper or a training treat depending on how you break it up.

One thing worth knowing about all three

Canada has no mandatory nutritional standard for pet food. The Canadian Food Inspection Agency regulates animal health and the import and export of animal products — it does not routinely verify what is in a bag sold domestically. AAFCO nutrient profiles, the benchmark most brands cite, are voluntary here.

That applies equally to kibble, raw and freeze-dried, so it is not an argument for any of them. It is an argument for reading the nutritional adequacy statement on whatever you buy, and for knowing whether a product is a complete meal or a topper. Many toppers are not formulated as complete diets and are not meant to be one — that is on the panel, and it is the single most common mix-up we untangle at the counter.

Come argue with us

Bring the bag you are feeding now, or a photo of the back panel, and we will go through it with you at 2637 W 4th Ave in Kitsilano, open daily 9 am to 7 pm. If you want to test a format without committing, ask — the smallest size of most of these exists for exactly that reason. And anything clinical, a dog losing weight, itching, or bringing food back up, goes to your veterinarian first. We cannot diagnose, and we will say so.
