Cold-pressed, kibble, fresh, and raw: what dog food processing actually means
Eight bags on a shelf, eight different words on the front, and no obvious way to tell which differences are real. Here is what each process actually is, what the difference does and does not tell you, and the checks that beat the marketing language.
How each type is actually made
The words on the front of the bag mostly describe a manufacturing process. Here is what each one means in plain terms, process only.
Extruded kibble
Ingredients are ground into a dough, then cooked under high heat and pressure and forced through a shaped opening called a die. The sudden drop in pressure makes the dough expand, which is why kibble is light and porous. The pieces are then dried and usually coated with fats or flavor toppings. This is the most common process on the shelf, and it produces a shelf-stable, low-moisture food.
Cold-pressed
Ingredients are ground and then compressed into a pellet at a lower temperature than extrusion, typically with brief heating rather than sustained high-temperature cooking. Because the mixture is pressed rather than expanded, the result is denser and does not puff up the way kibble does. It is still a dry, shelf-stable food.
Fresh or refrigerated
Ingredients are cooked at comparatively gentle temperatures, then chilled or frozen and shipped cold. These foods keep much of their moisture, which is part of why they look and smell like food rather than pellets, and it is also why they need refrigeration and have a shorter open life.
Freeze-dried and raw
Raw ingredients are frozen, then placed under vacuum so the frozen water leaves as vapor without the food being cooked. That produces a dry, light product meant to be rehydrated or fed as is. Frozen raw skips the drying entirely and is sold and stored frozen. Neither is cooked in the way kibble or canned food is. Raw diets carry documented food-safety handling considerations for the household as well as the dog, and the FDA publishes handling guidance for pet food generally.
Canned
Ingredients are sealed into the can and then heat-sterilized inside it, which is what makes an unopened can shelf-stable for a long time. Canned food is high in moisture by design, typically far wetter than any dry format, which matters later when you compare cost.
What the processing difference does and does not tell you
This is the part the packaging will not tell you plainly, so here it is.
Processing describes how a food was made. It does not describe what went into it. A carefully formulated extruded food and a poorly formulated cold-pressed one are not ranked by their process, and two foods sharing a process can differ enormously in ingredient quality, formulation, and the expertise behind them. The process word on the front of the bag is a manufacturing fact, not a quality grade.
The process word on the front of the bag is a manufacturing fact, not a quality grade.
It is also worth being straight about the evidence. Direct head-to-head research comparing long-term health outcomes in dogs across these processing methods is limited. Marketing language often moves well ahead of what has actually been demonstrated. No processing method has been established as medically superior to the others for dogs generally, and this article is not going to imply otherwise.
What does carry a defined meaning is whether a food is complete and balanced for a life stage, which is a nutritional-adequacy standard applied to the finished food no matter how it was manufactured. That standard, described below, is a far more useful comparison point than the process word.
The checks that actually matter
These are the questions worth asking of any brand, including any brand this site ever links to. They are more informative than the word on the front of the bag.
- Is there an AAFCO complete-and-balanced statement, and for which life stage? The Association of American Feed Control Officials publishes the nutrient profiles most pet foods are formulated against, and the statement on the label tells you whether the food is intended for growth, adult maintenance, all life stages, or is for intermittent feeding only. Large-breed puppies have a separate growth qualifier worth looking for. AAFCO explains how to read this statement.
- Does the company employ a qualified nutritionist? Ask whether formulation is done by someone with graduate training in animal nutrition or board certification in veterinary nutrition, and whether that person is on staff or an occasional consultant.
- Where is the food actually manufactured? Some companies own their plants, others use contract manufacturers. Neither is automatically better, but a company that will not answer the question is telling you something.
- Were feeding trials run? A label can say a food was formulated to meet a nutrient profile, or that it passed AAFCO feeding trials. The second is a higher bar and a different sentence on the label. Both appear in the adequacy statement.
- What is the recall history? The FDA maintains a public recalls and withdrawals database. A past recall is not automatically disqualifying, but how a company handled it is informative.
If a brand cannot answer these five questions clearly, the processing word on the front is not going to make up the difference.
Cost: per pound and per meal, not per bag
Bag prices are close to meaningless for comparison, because bag sizes differ and, more importantly, so does calorie density. A dense food may feed a dog for more days per pound than a light, airy one, and a high-moisture food is partly water by weight.
Two numbers make comparison honest. First, price per pound, which normalizes different bag sizes. Second, and better, price per meal or per day: take the feeding guide for your dog's weight, work out how much of that specific food it calls for daily, and divide the cost accordingly. The calorie content per cup or per kilogram is usually printed on the label or the product page, which is what makes this arithmetic possible. A food that looks expensive per bag can land mid-range per meal, and the reverse happens too.
Because a dog may simply refuse a food regardless of how it was made or what it cost, this is also the point where small quantities are worth more than a bulk price.
A cold-pressed line, shown as an example rather than a recommendation
To make the category concrete rather than abstract, here is one cold-pressed brand you can look at and run the section-three checks against yourself. Nextrition is cold-pressed at a lower temperature than extruded kibble, sold as four single-protein recipes, with trial packs available so a dog can try a food before you commit to a full bag.
- Variety trial 4-pack, which covers all four proteins in small sizes
- Trial packs if you would rather start with one protein
- Full-size single-protein recipes: chicken, beef, lamb, and salmon
Running the first check ourselves: each of these four recipes carries an AAFCO statement reading that it "is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for All Life Stages including growth of large size dogs (70 lb. or more as an adult)." That is the complete-and-balanced statement described above, at the broadest life stage. The manufacturing location is not stated on the product pages, which is exactly the kind of question worth asking the company directly. Pricing changes, so check the current figures on their pages and run the per-meal arithmetic above.

Transitions and picky dogs
Trial sizes exist because dogs are individuals. A food can be well formulated, well made, and correctly priced, and a particular dog can still turn away from the bowl. Buying a small quantity first is a practical way to find that out without a large bag going to waste.
When you do switch, switching gradually is the standard advice: mix a small proportion of the new food into the current one and increase it over roughly a week, watching how the dog handles each step. An abrupt change is more likely to upset a dog's stomach than a slow one. If your dog has a medical condition, is on a prescribed diet, or shows any symptoms such as vomiting, diarrhea, appetite loss, or weight change, talk to your veterinarian before changing foods rather than working it out from a label.
Questions people ask
Is cold-pressed better than kibble?
Neither has been established as medically superior for dogs generally, and direct comparative outcome research is limited. They are different manufacturing processes. The more useful comparison is the complete-and-balanced statement, who formulated the food, where it is made, whether feeding trials were run, and recall history.
What does "complete and balanced" actually mean?
It means the food is intended to meet an established nutrient profile for a stated life stage, such as growth, adult maintenance, or all life stages. The statement appears on the label and names the life stage, and AAFCO publishes the profiles behind it.
Why is price per bag misleading?
Bag sizes and calorie density both vary, and high-moisture foods carry water weight. Price per pound is better, and price per meal, using the feeding guide for your dog's weight, is better still.
How slowly should I change foods?
The common approach is to blend increasing proportions of the new food into the old across about a week. If your dog has a medical condition or reacts badly at any point, check with your veterinarian.
