Air-dried and freeze-dried dog foods use different drying processes, but the buying decision starts with the same checks: is the exact product complete, how much should you feed, what preparation is required and what will it cost per day? Neither processing name proves that a food is the best choice for your dog.
Both categories include products that can look remarkably similar in a shopping result while serving different purposes. A bag of complete meals and a small bag of meat treats should never be compared as interchangeable main diets.

Understand the processing description
ZIWI describes its air-drying process as using circulating warm air. Natures Menu explains freeze-drying through removal of moisture from frozen food under vacuum. Those descriptions tell you something about manufacture; they do not by themselves establish nutritional superiority or a particular health outcome.
Read the manufacturer’s explanation for the product you are considering. Words such as raw, dried, gently prepared and complete refer to different aspects of the food and should not be treated as synonyms. Ask the manufacturer when a description leaves its preparation or handling unclear.
Texture also varies between recipes. Before committing to a large order, consider whether the pieces can be served as directed and whether your dog can eat them comfortably. A photograph cannot establish their hardness, size or behaviour after water is added.
First separate meals from treats and toppers
Check for a complete-feed statement and the intended life stage on the exact pack. Complementary products need an appropriate wider diet; they are not automatically suitable as the sole food. A brand may sell both categories, even with similar meat names and packaging colours.
Natures Menu’s current UK freeze-dried range includes Complete & Balanced products. Be especially careful to distinguish these from its treat products when searching. ZIWI’s UK range includes Original Air-dried Mackerel & Lamb as a complete-meal option. Verify the label on the size and recipe you actually buy.
| Pack detail | Why it matters |
|---|---|
| Complete or complementary | Establishes the intended role in the daily diet |
| Life stage | Checks whether the recipe is intended for your dog |
| Daily quantity | Allows a useful cost comparison |
| Water instructions | Shows whether and how to prepare the food |
| Storage after opening | Helps you choose a pack you can finish correctly |
Compare the portion you will actually serve
Drying removes water, so bag weight is a poor shortcut for comparing these foods with wet meals. Start with each product’s feeding guidance for the same dog, then seek individual advice where needed. Do not transfer the gram amount from an existing wet food to a dried product.
For an illustrative calculation, a £30 bag lasting 15 days costs £2 per day. A £24 bag lasting eight days costs £3 per day. These are invented prices and durations, not brand quotes or recommended rations. Add any necessary companion food when the product is used as a topper.
If instructions require adding water, use the specified preparation method. The water changes the served weight and texture but does not add another bag’s worth of nutrients. Keep fresh drinking water available and ask your vet about any individual hydration or feeding concerns.
Current UK examples to investigate

Find ZIWI air-dried Mackerel & Lamb dog food on Amazon UK if you want to investigate ZIWI’s air-dried format. Check that the listing matches the Mackerel & Lamb dog-food recipe and the required bag size. Brand names alone can return treats, cat food and different processing ranges.
Find Natures Menu Complete & Balanced freeze-dried chicken dog food on Amazon UK for a freeze-dried meal example. Look for the Complete & Balanced chicken food rather than chicken treat bites. These are item-specific search links; they do not guarantee an available listing, seller or price.
The useful comparison is between two suitable exact recipes, using their labels and your dog’s needs. Our main dog food guide includes other formats if neither dried option fits the budget or routine.
Ask about handling as well as convenience
Cupboard storage does not mean you can ignore hygiene or expiry instructions. Follow the pack’s directions for sealing, storage, utensils and any prepared leftovers. Keep the original label and batch details, especially if you transfer a bag into an outer container.
Where a product is made from raw animal ingredients, ask the manufacturer about its processing and handling guidance. UKHSA and APHA advise that raw pet products can carry harmful bacteria and require appropriate hygiene. Do not interpret drying alone as a verified sterilisation claim.
Discuss dietary changes with your veterinary team if your dog has medical needs, or if someone in the household needs additional infection precautions. Choose a manageable pack, introduce the food according to suitable advice and record the quantity served. That provides a clearer basis for judging suitability than paying extra for a processing label without checking the rest of the pack.
