Your dog’s bowl deserves better than mystery ingredients and high-heat shortcuts.
The best air dried dog food sits in a category of its own, closer to raw feeding in nutrient profile but with lower pathogen risk than raw and no freezer requirements. More pet owners are making the switch, and the reasons go beyond marketing.
This guide covers what air drying actually does to protein bioavailability and amino acid retention, how to read a guaranteed analysis correctly, which brands hold up under scrutiny, and what feeding air dried food actually costs day to day.
No fluff. Just the information you need to make a confident decision for your dog.
What Is Air Dried Dog Food?
Air dried dog food is produced by slowly removing moisture from raw ingredients with gently heated, circulating air over an extended drying period. The result is a shelf-stable product that sits nutritionally between raw feeding and conventional kibble, without the high-heat processing that changes ingredient structure.
Moisture content in finished air dried products typically falls between about 12 and 18% (Ziwi Peak guarantees a maximum of 14%, Open Farm 18%). Compare that to raw food at 60 to 80% moisture and standard kibble at around 10%, and you start to understand why air dried food sits in its own category.
Low moisture stops bacteria like Salmonella and E. coli from multiplying, and many brands add a heat or pathogen-reduction step to the drying process. That is the key practical difference from raw feeding. But drying alone is not a guaranteed kill step, so air dried food lowers the contamination risk rather than eliminating it. Dogs still get a nutrient profile close to raw, without the refrigeration requirements.
How Air Drying Differs from Freeze-Drying and Dehydration
These 3 processes get lumped together constantly. They are not the same.
| Process | Temperature | Moisture Removal Method | Key Trade-off |
|---|---|---|---|
| Air drying | Gentle heat (exact temperatures vary by brand) | Slow airflow over time | Longer process with good nutrient retention |
| Freeze-drying | Below freezing (-40 to -50°C) | Vacuum-pressure sublimation | Best nutrient retention but highest cost |
| Dehydration | Low to moderate heat (varies by brand) | Heated airflow | Faster process with some loss of heat-sensitive nutrients |
| Kibble extrusion | High heat (often above 100°C) and pressure | High-heat, high-pressure cooking | Lowest cost but greatest nutrient degradation |
Air dried food usually comes as jerky-like pieces you scoop straight from the bag. Ziwi Peak and Open Farm both use this format, and both market the same recipes as complete meals or as toppers on kibble.
One thing worth knowing: air dried is not the same as dehydrated, even though some brands use the terms interchangeably on packaging. None of these terms has a regulated definition, so read the label. If a label says “dehydrated” and the protein source is listed as a meal rather than whole meat, that is a completely different product.
What Nutrients Are Preserved in Air Dried Dog Food?
Gentler processing tends to protect nutrients that high-heat processing damages. A 2022 study published in Animals (Basel) found that dry food made from fresh chicken meat contained more essential amino acids than versions made from chicken meal, with the highest in vitro digestibility of the three formulations tested (Montegiove et al., Animals, 2022). That study compared kibbles, not air dried food, but it shows that how ingredients are processed before they reach the bag matters.
The reason comes down to heat. Heat processing can damage proteins and amino acids, especially through browning (Maillard) reactions that reduce available lysine. Air drying uses less heat than extrusion, which means the amino acid profiles in beef, lamb, and venison proteins are more likely to arrive at your dog’s bowl intact.
Enzyme and Vitamin Retention
Lower processing temperatures generally mean less heat damage than kibble extrusion.
- Some naturally occurring enzymes may survive gentle drying, though healthy dogs make their own digestive enzymes and don’t need them from food (Freeman et al., JAVMA, 2013)
- Heat-sensitive vitamins are likely better preserved than in extruded processing, although complete and balanced foods of every type are formulated to cover processing losses
- Omega-3 and omega-6 fatty acids are likely less oxidized due to lower processing temperature
- Taurine, which dogs normally make from methionine and cysteine and which matters for heart health, is guaranteed in most air dried formulas (Ziwi Peak Beef lists taurine at minimum 0.05%)
Freeze-dried raw foods showed digestibility values of 90% or higher for most essential amino acids in a University of Illinois study (Oba et al., Journal of Animal Science, 2023). Air dried products weren’t tested. In a separate 2024 Illinois feeding study, freeze-dried and frozen raw diets outperformed extruded kibble on protein digestibility.
How to Read the Guaranteed Analysis on Air Dried Dog Food Labels
This trips up a lot of people, including me the first time I switched one of my dogs to air dried.
The guaranteed analysis on any dog food label is listed on an “as fed” basis, meaning it includes the moisture content of the food. Because air dried food contains only about 12 to 18% moisture compared to wet food at 75 to 80%, the protein percentages look inflated relative to wet food but comparable to kibble.
Dry matter basis (DMB) is how you compare formulas fairly. The formula: take the reported nutrient percentage, divide by (100 minus the moisture percentage), then multiply by 100.
Example: Ziwi Peak Beef lists crude protein at 38% on an as-fed basis with 14% max moisture. On a dry matter basis, that calculates to roughly 44% protein. That is a high-protein diet by any standard. AAFCO requires a minimum of 18% protein (DM) for adult dogs and 22.5% for growth and reproduction.
What Are the AAFCO Standards for Air Dried Dog Food?
AAFCO does not regulate the manufacturing process. It sets nutritional minimums and label standards. A product being “air dried” says nothing about whether it qualifies as complete and balanced nutrition for your dog.
In 2023, AAFCO’s membership approved the first major pet food label update in more than 40 years. The new model regulations, published in the 2024 Official Publication, move the intended use statement to the lower third of the front panel and add a redesigned Pet Nutrition Facts box closer to human food labeling, with the nutritional adequacy statement at its bottom. AAFCO recommends that states give brands six years to comply.
Complete and Balanced vs. Supplemental Feeding
“Complete and balanced” means the formula meets AAFCO’s minimum nutrient profile for at least one life stage.
“Intermittent or supplemental feeding only” means it does not. Some air dried toppers and mixers fall into this category. Feeding them as a sole diet creates nutritional gaps.
There are 2 main ways a brand can substantiate a “complete and balanced” claim (FDA). First, the formula is shown to meet AAFCO nutrient profiles by calculation or laboratory analysis. Second, an AAFCO feeding trial uses real dogs over a defined period to confirm the food actually sustains health. Feeding trial substantiation is harder to achieve and more meaningful. The label will say “Animal feeding tests using AAFCO procedures substantiate that [Product Name] provides complete and balanced nutrition” if a trial was conducted.
Life Stage Coverage in Air Dried Formulas
AAFCO has 2 nutrient profiles for dogs, growth and reproduction and adult maintenance. A food that meets the growth and reproduction profile can be labeled for all life stages.
- All life stages: Meets the highest nutritional bar, covering puppy growth requirements. Ziwi Peak Beef carries this designation with the exception of large breed puppies (over 70 lbs. as adults), while Ziwi’s Lamb, Venison, and Mackerel & Lamb recipes include large-size growth.
- Adult maintenance: Meets minimums for adult dogs only. Not sufficient for puppies.
- Growth: Formulated specifically for puppies and pregnant or nursing females.
The National Research Council (NRC) publishes the nutrient requirement research that AAFCO’s profiles are built on, and AAFCO updates its profiles periodically. When comparing air dried brands, check whether the AAFCO statement reflects formulation compliance or an actual feeding trial.
What Ingredients Separate the Best Air Dried Dog Foods from Average Ones?
You can learn most of what you need to know about an air dried dog food from the first 5 ingredients and the synthetic additive list. Everything else is detail.
Minimally processed formats are growing fast. In NielsenIQ data for U.S. pet retail, sales of 100% freeze-dried dry pet food grew 7.5% in the 52 weeks ending June 2024, while traditional kibble declined 1.8% (NielsenIQ, reported by Petfood Industry, 2024). That growth has attracted a lot of brands into minimally processed formats, including air dried, and ingredient quality varies widely.
Organ Meat Content: Why It Matters in Air Dried Formulas
Organ meat is not a filler. It is one of the most nutrient-dense ingredients in any dog food formula.
- Liver delivers preformed vitamin A, B vitamins, and iron in highly bioavailable forms
- Heart is one of the best natural sources of taurine and CoQ10
- Kidney provides B12, riboflavin, and selenium
- Spleen contains high levels of iron and vitamin C
Ziwi Peak’s beef recipe lists beef, beef tripe, beef heart, beef lung, beef liver, and beef kidney as its first 6 ingredients. That organ inclusion helps explain how the formula hits 38% crude protein on an as-fed basis without relying on any plant-based protein sources.
Brands that use generic “meat meal” as a primary protein source are using a rendered ingredient, meaning it was processed at high heat before the air drying stage. The end product is not the same as a formula built on whole fresh meats and organs.
Synthetic Preservatives to Avoid
Finding BHA, BHT, or ethoxyquin in an air dried dog food is a red flag. These synthetic antioxidants are used to extend fat shelf life in lower-quality formulas.
BHA (Butylated Hydroxyanisole) is listed by the National Toxicology Program as reasonably anticipated to be a human carcinogen, based on animal studies. BHT (Butylated Hydroxytoluene) is not on that list, but it is a closely related synthetic preservative that many owners prefer to avoid.
A well-formulated air dried product uses mixed tocopherols (natural vitamin E) and citric acid for preservation. Ziwi Peak uses exactly this approach. The low moisture content of air dried food itself acts as a natural preservation mechanism. You do not need synthetic preservatives in a properly air dried formula. If you see them on the label, the formulation was compromised somewhere in the process.
Also watch for carbohydrate sources. Sweet potato and chickpeas are not harmful in small quantities, but some brands use them to bulk out formulas and reduce per-serving meat content. Tapioca starch adds calories with little else. Ziwi Peak recipes contain no grains or potatoes, which keeps carbohydrate content very low.
What Are the Best Air Dried Dog Foods Available?
These rankings are based on 5 criteria: protein source quality, AAFCO life stage designation, ingredient integrity (organ meat inclusion, absence of synthetic preservatives), caloric density, and country of manufacture. Price per day is calculated for a 30 lb neutered adult dog eating about 700 to 800 kcal a day, using brand-site prices in 2026.
Best Air Dried Dog Food for Overall Quality
Ziwi Peak Air Dried consistently tops comparisons for ingredient quality. The beef recipe guarantees at least 38% crude protein and 30% crude fat on an as-fed basis, which works out to a dry matter protein of approximately 44%. The recipes we checked list organ meats in the first 6 ingredients.
- 96% meat, organs, seafood, and bone by formulation
- No grains, potatoes, rendered meals, or synthetic preservatives
- AAFCO all life stages (the Beef and Chicken recipes exclude large breed puppies; Lamb, Venison, and Mackerel & Lamb include them)
- Manufactured in New Zealand, with no FDA-listed recalls that we could find
- Cost: approximately $7 to $10 per day for a 30 lb dog fed Ziwi as a complete diet
Took me a while to get used to how little you feed. Because it is calorie-dense at around 4,900 kcal/kg for the beef recipe, the daily portion looks small compared to kibble. That is normal. Do not free-feed air dried food.
Best Air Dried Dog Food for Small Breeds
Small breed dogs have faster metabolisms and higher caloric needs per pound of body weight. They also tend to have more sensitive stomachs, which makes the short, meat-first ingredient lists of most air dried formulas a practical advantage. Small dogs also eat small portions, which keeps the daily cost of a premium air dried food manageable.
Open Farm Air Dried is a strong option here. The Pollock & Lamb recipe carries an AAFCO all life stages designation (including large-size growth) and is built on wild-caught pollock, lamb, and lamb organs, with bone broth and a fruit and vegetable blend.
| Brand | Protein (as-fed) | AAFCO Statement | Best For | Price/day (30 lb dog) |
|---|---|---|---|---|
| Ziwi Peak | 38–44% | All life stages | Overall quality and sensitive stomachs | $7.00–$10.00 |
| Open Farm | 29–40% | Adult maintenance / all life stages | Transparency-focused buyers and ethical sourcing | $9.00–$13.00 |
Ziwi Peak Beef and Chicken exclude large breed puppy growth (70+ lbs. adult weight); Ziwi Lamb and Open Farm Pollock & Lamb and Chicken include it. Open Farm Surf & Turf is for adult maintenance only.
K9 Natural, Stella & Chewy’s, and Orijen often appear on air dried lists, but their shelf-stable raw lines are freeze-dried, not air dried.
Best Air Dried Dog Food for Large Breeds
Large breed dogs need controlled calcium-to-phosphorus ratios to support bone development and joint health. Some “all life stages” air dried formulas exclude large breed puppies specifically because of this, so check each recipe.
Ziwi Peak Lamb is a strong large breed option for adult dogs and growing puppies alike, since it is labeled for all life stages including growth of large size dogs. Open Farm’s Pollock & Lamb and Chicken air dried recipes carry the same large-size growth designation.
For large breed adults, look for formulas with naturally occurring glucosamine and chondroitin from joint-rich tissues. Ziwi Peak lists chondroitin sulfate at minimum 3,000 mg/kg and glucosamine at minimum 1,000 mg/kg in the lamb recipe. That comes from the inclusion of ground bone and cartilage, not an added joint supplement.
Best Budget Air Dried Dog Food
There is no true budget air dried food when you feed it as a complete diet. Open Farm’s bags cost a little less than Ziwi Peak’s, but its recipes carry fewer calories per kilogram, so the cost per day ends up similar or higher.
Using air dried food as a high-value topper on a quality kibble base is a realistic middle ground. You get the palatability boost and partial nutrient upgrade without the full cost of air dried feeding.
How Does Air Dried Dog Food Compare to Raw and Kibble?
A 2024 University of Illinois Urbana-Champaign study found that extruded kibble generally had the lowest digestibility values compared to frozen raw and freeze-dried raw diets, and kibble-fed dogs produced more feces (Geary et al., Translational Animal Science, 2024). That research did not include air dried food, but its lower processing temperatures suggest it falls closer to freeze-dried than to kibble on the nutrient preservation scale.
Pathogen Risk Comparison: Air Dried vs. Raw
This is where air dried makes a practical argument over raw feeding.
Salmonella prevalence in raw pet foods has ranged from 0 to 80% across studies published since 2002 (Dhakal et al., Comprehensive Reviews in Food Science and Food Safety, 2024). In an FDA Center for Veterinary Medicine study, 15 of 196 raw dog and cat food samples tested positive for Salmonella and 32 for Listeria monocytogenes, while Salmonella turned up in only 1 of 480 dry and semi-moist samples (FDA).
Air drying lowers moisture enough to stop Salmonella and E. coli from multiplying, and brands like Ziwi say they combine a pathogen-reduction drying process with finished-product testing. That makes air dried food meaningfully safer than raw while retaining most of the nutritional advantages. It is not risk-free, though: the same review lists recalls of raw dehydrated dog food for Salmonella, so wash your hands and the bowl as you would with raw. The FDA’s position is that raw pet food carries inherent pathogen risk, and air dried is the format that sits closest to raw in nutrition with a lower risk profile.
Cost Per Day: Air Dried vs. Kibble vs. Freeze-Dried
Premium kibble is still the most cost-effective complete diet. And the cost gap is bigger than most people expect, even after accounting for smaller feeding volumes.
- Traditional kibble (premium): about $1 to $2 per day for a 30 lb dog
- Air dried (e.g., Ziwi Peak): about $7 to $10 per day
- Air dried (e.g., Open Farm): about $9 to $13 per day
- Freeze-dried (e.g., Primal, Stella and Chewy’s): often $10 to $15 or more per day
- Raw feeding (DIY or commercial): varies widely depending on protein source and whether you make it yourself
NielsenIQ data from June 2024 shows freeze-dried dog food averages $35.23 per pound at retail versus $2.52 per pound for traditional kibble and $4.22 per pound for kibble-plus formats (NielsenIQ, 2024). Air dried, at roughly $24 to $28 per pound for 2 lb bags of Ziwi Peak or Open Farm, sits between kibble-plus and freeze-dried on a cost-per-pound basis.
One important note: because air dried food is calorie-dense, you feed less volume per day than you would with kibble. A bag lasts longer than the per-pound price suggests at first glance.
What Are the Health Benefits of Air Dried Dog Food Backed by Research?
The research base for air dried dog food specifically is still developing. Most studies compare kibble to raw or freeze-dried, not air dried directly. Given the shared low-heat processing philosophy, those findings may point in the same direction, but that hasn’t been tested.
Gut Microbiome and Digestibility
A 2024 study from Oklahoma State University and the University of Florida published in Frontiers in Veterinary Science found that dogs fed a raw meat-based diet had higher fecal IgA, IgG, and intestinal alkaline phosphatase (IAP) than kibble-fed dogs, while blood markers of inflammation were similar in both groups. IAP is a key marker of intestinal barrier function and gut health (Frontiers in Veterinary Science, 2024).
That matters practically. A well-functioning gut barrier supports nutrient absorption, and in the 2024 Illinois study, dogs fed frozen raw and freeze-dried raw diets had firmer stools and less fecal output than dogs fed kibble.
A separate study in Comparative Clinical Pathology found that dehydrated natural dog food was linked to better fiber and mineral digestibility and stronger antioxidant and immune markers compared to extruded dry kibble, though dry matter and fat digestibility were lower and fecal volume was higher (Cecere et al., 2025). Dehydrated and air dried share the same core low-temperature moisture-removal approach.
Skin, Coat, and Weight Management
Omega-3 and omega-6 fatty acid preservation is one of the clearest nutritional differences between air dried and extruded kibble.
Heat and oxygen exposure can oxidize fats, and oxidized fats are less useful nutritionally. Air dried processing uses less heat, which is why omega fatty acid content in a well-formulated air dried food is likely closer to the source ingredient profile, though storage and antioxidant protection matter too.
For coat health: The omega-3 content in Ziwi Peak’s Mackerel & Lamb recipe comes from whole mackerel and New Zealand green mussel, both minimally processed before drying. The taurine content from naturally occurring sources in heart muscle supports cardiac function as a secondary benefit.
On weight management: air dried food is calorie-dense, so small portions carry a lot of calories. Some dogs feel more satisfied on high-protein meals, which can help with portion control, but it is just as easy to overfeed a dense food. This is your mileage may vary territory — it depends on the individual dog and how strict you are with portion control.
How Much Air Dried Dog Food Should You Feed Per Day?
Air dried dog food is calorie-dense. That is the first thing to understand before you calculate portion sizes.
Standard premium kibble runs roughly 3,300 to 4,000 kcal per kilogram. Ziwi Peak Beef runs 4,900 kcal/kg. That difference means your daily portion of air dried food will look noticeably smaller than what you were feeding in kibble, and that is correct.
59% of dogs in the United States were classified as overweight or obese in the Association for Pet Obesity Prevention’s 2022 survey. Overfeeding air dried food is easy to do precisely because the bag looks barely touched compared to a kibble bag.
Daily Feeding Amounts by Dog Weight
These figures are based on an average spayed or neutered adult dog at maintenance activity, using the standard veterinary estimate of 1.4 to 1.6 times resting energy requirement (Merck Veterinary Manual) and Ziwi Peak Beef at 4,900 kcal/kg. Foods with fewer calories per kilogram need proportionally more grams.
| Dog Weight | Approx. Daily Amount (air dried) | Approx. Daily Calories |
|---|---|---|
| 5 lbs | 37–42g | 180–205 kcal |
| 10 lbs | 62–71g | 305–350 kcal |
| 25 lbs | 124–141g | 605–690 kcal |
| 50 lbs | 208–238g | 1,020–1,165 kcal |
| 75 lbs | 282–322g | 1,380–1,580 kcal |
These are starting points, not fixed targets. Weigh your dog every 2 to 3 weeks during the first 2 months and adjust up or down based on body condition score. Our dog calorie calculator can give you a personalized daily calorie target to divide by your food’s kcal/kg.
Active working breeds, nursing females, and dogs recovering from illness all need more. Senior dogs with reduced activity typically need 10 to 20% less than the maintenance range above.
Transitioning from Kibble to Air Dried Dog Food
Never switch cold turkey. The high protein and fat content of most air dried formulas hits differently than kibble, and a sudden change causes digestive upset in most dogs.
A 7 to 10 day transition works for most dogs.
- Days 1-3: 25% air dried, 75% kibble
- Days 4-6: 50% each
- Days 7-9: 75% air dried, 25% kibble
- Day 10+: 100% air dried
Some dogs with sensitive stomachs need 14 days. If you see loose stools that persist beyond day 3 on a given ratio, hold at that ratio for an extra 2 days before moving forward.
Rehydrating air dried food with warm water is worth trying. It slows eating pace, aids digestion, and increases palatability for picky dogs. Add a little warm water and let it sit for 3 to 5 minutes before serving.
Is Air Dried Dog Food Safe for Puppies and Senior Dogs?
Life stage matters significantly when choosing an air dried formula. Not every product covers every stage.
Air Dried Dog Food for Puppies
AAFCO requires a minimum of 22.5% protein (dry matter basis) for growth, which most premium air dried formulas well exceed. Ziwi Peak Beef sits at approximately 44% DM protein. That is not the concern.
The calcium-to-phosphorus ratio is. AAFCO sets acceptable Ca:P ratios at 1:1 to 2:1 for growth stage diets.
Large breed puppies (adult weight 70+ lbs) have stricter requirements. A study published in the Journal of the American Veterinary Medical Association found that calcium concentrations exceeded recommended limits in some dry maintenance foods labeled for all life stages, underscoring why large breed puppies need formulas specifically validated for their size (JAVMA, 2013).
Check the AAFCO statement carefully. A label reading “formulated for all life stages except for growth of large size dogs” is not suitable as a sole diet for a large breed puppy. Ziwi Peak Beef carries this exclusion, while Ziwi Lamb and Open Farm’s Pollock & Lamb and Chicken recipes are labeled for growth of large size dogs. If you’re unsure, contact the brand directly about calcium and phosphorus values before committing.
Air Dried Dog Food for Senior Dogs
Senior dogs do not have an AAFCO life stage category. There is no regulatory requirement for “senior” formulas. Any product labeled “adult maintenance” or “all life stages” technically qualifies for senior feeding.
The real concern for seniors is phosphorus. Dogs with chronic kidney disease (CKD) cannot filter phosphorus effectively. As phosphorus builds up in the blood, it accelerates kidney damage and can pull calcium from bones.
Air dried diets are high in organ meat and ground bone, both of which add phosphorus. For a healthy senior dog, this is fine. For a dog with diagnosed kidney disease, it is not. AAHA’s 2023 Senior Care Guidelines note that IRIS recommends phosphorus control for dogs with kidney disease, with protein restriction considered at IRIS Stage 2 and recommended at Stage 3.
For seniors without diagnosed kidney or liver conditions:
- Air dried food is appropriate and often beneficial due to high protein retention
- Joint support from natural glucosamine and chondroitin in bone-inclusive formulas is a practical bonus
- Reduced portion size accounts for lower activity and slower metabolism
If your senior dog has any diagnosed organ condition, get a vet consult before switching to a high-protein air dried formula. That is not optional.
What Do Veterinary Nutritionists Say About Air Dried Dog Food?
The veterinary nutrition community supports careful, complete and balanced feeding of healthy dogs in many formats. But there are specific concerns about minimally processed diets worth knowing.
The WSAVA Framework and Where Air Dried Brands Land
The WSAVA (World Small Animal Veterinary Association) publishes a framework of questions for evaluating pet food manufacturers, not a list of approved brands. The key questions concern whether the company employs a qualified nutritionist (a PhD in animal nutrition or board certification by the ACVN or ECVCN) and who formulates the recipes, whether the label claim is backed by feeding trials or formulation, and what quality control processes exist at the manufacturing level.
Few air dried brands publish answers to WSAVA’s manufacturer questions in as much detail as Hill’s, Purina, or Royal Canin. That does not mean the food is nutritionally inadequate. It means the transparency layer differs.
Before you commit to any brand, it is worth emailing the company the WSAVA questions. How quickly and specifically they answer tells you a lot.
Common Veterinary Concerns About Minimally Processed Diets
A review in the Journal of the American Veterinary Medical Association led by board-certified veterinary nutritionist Dr. Lisa Freeman of Tufts University concluded that most claimed health benefits of raw meat diets have not been scientifically evaluated, while the evidence for infectious disease risk is of better quality (Freeman et al., JAVMA, 2013).
Air drying reduces that specific concern, though the same review notes that raw dried treats carry bacterial risks similar to raw diets. And 3 other professional concerns remain relevant:
- Long-term feeding trial data: Most air dried brands use nutrient formulation compliance rather than AAFCO feeding trials. Real-world multi-year outcome data is limited.
- High fat and caloric density: Dogs predisposed to pancreatitis are at higher risk on high-fat formulas. Breeds like Miniature Schnauzers and Cocker Spaniels need closer monitoring.
- Protein load in compromised dogs: High protein does not cause kidney disease in healthy dogs, and AAHA notes healthy pets don’t need protein restriction. But protein and phosphorus need managing in dogs with existing kidney impairment (AAHA, 2023).
Well, here is the practical takeaway from all of this: if your dog is healthy, air dried is a well-supported choice. If your dog has a diagnosed condition affecting the liver, kidneys, or pancreas, get a board-certified veterinary nutritionist involved before switching.
Where to Buy Air Dried Dog Food and What It Costs
Availability has expanded significantly. Air dried dog food is now easy to find at mainstream pet retailers, part of a broader shift toward minimally processed formats that saw 100% freeze-dried food sales grow 7.5% in the year to June 2024 while traditional kibble declined (NielsenIQ, 2024).
Retail and Online Availability
Chewy carries one of the widest online selections of air dried dog food in the US, including Ziwi Peak, with free shipping on orders over $49.
PetSmart and Petco both stock premium air dried brands in-store and online. Petco’s Repeat Delivery program has offered 35% off a first order (with a cap) and about 5% off ongoing orders, so check the current terms. Subscription pricing is the most practical way to reduce the ongoing cost of feeding air dried long-term.
Brand direct-to-consumer purchasing (Ziwi Peak US, Open Farm) often includes subscription options and sometimes free shipping above a spend threshold. Worth checking each brand’s site before defaulting to a marketplace.
Price Tiers and Real Cost Comparison
A few things to factor in that make the per-bag price less alarming than it looks at first.
Air dried food is nutrient-dense. A 2.2 lb bag of Ziwi Peak Beef lasts a 30 lb dog roughly 6 to 7 days when fed as a complete diet (about 140 to 160 g a day), and larger bags cost less per pound. That math is very different from how quickly a 2 lb bag of kibble disappears.
| Source | Selection | Subscription Option | Notes |
|---|---|---|---|
| Chewy | Widest online range | Yes (Autoship, about 5% off repeat orders) | Free shipping on orders over $49 |
| Petco | Strong in-store range | Yes (capped first-order discount, about 5% ongoing) | Price matching available |
| PetSmart | Good mainstream selection | Yes (Autoship) | In-store pickup available |
| Brand direct | Full product line | Varies by brand | Best for loyal single-brand buyers |
For storage: once opened, keep air dried food in its original sealed bag at room temperature, away from heat and light. Ziwi Peak’s own guidance is to feed it before the best-before date and within 8 weeks of opening.
Dogs with sensitive stomachs transitioning to air dried sometimes do better with a slow rollout over 14 days rather than the standard 7 to 10. The high fat content is typically the adjustment factor, not the protein. If you want to compare options across healthy dog treat categories while you transition, keeping treats low-fat during the switch helps the digestive adjustment.
And if you are figuring out what to feed a dog that does well on beef heart specifically, most premium air dried formulas already include it as a named ingredient. You get the nutritional benefit without sourcing it separately.
Breeds with known specific feeding requirements like the Bullmastiff, or large working breeds such as the Great Dane or Rottweiler, need portion calculations based on their maintenance energy requirements rather than the generic weight-based charts on packaging. These breeds’ higher adult body weights put them in a different caloric bracket than the averages suggest, and our Rottweiler feeding chart shows how much those numbers shift with age and weight.
FAQ on Best Air Dried Dog Food
Is air dried dog food better than kibble?
It can be. Air drying uses less heat than extrusion, and studies of minimally processed diets, mostly raw and freeze-dried, show higher digestibility and different gut markers compared to standard kibble (Translational Animal Science, 2024; Frontiers in Veterinary Science, 2024). Research on air dried food itself is still limited, and a complete and balanced kibble remains a sound diet.
What is the difference between air dried and freeze dried dog food?
Air drying uses gently heated, circulating air to remove moisture. Freeze drying uses sub-zero temperatures and vacuum pressure. Both preserve nutrients better than kibble. Freeze dried retains slightly more heat-sensitive compounds but costs significantly more per pound.
Can dogs eat air dried food every day?
Yes, provided the formula carries an AAFCO “complete and balanced” statement. Products labeled “intermittent or supplemental feeding only” are not suitable as a sole diet. Ziwi Peak and Open Farm air dried recipes are formulated as complete and balanced meals.
How much air dried dog food should I feed my dog?
Less than you expect. Air dried food is calorie-dense, often 3,400 to 5,000 kcal/kg. A 30 lb neutered adult dog eating Ziwi Peak Beef needs roughly 140 to 160g per day. Always calculate from the food’s actual kcal/kg figure, not kibble portion habits.
Is air dried dog food safe for puppies?
It depends on the formula. Look for an AAFCO “all life stages” designation. Large breed puppies (adult weight 70+ lbs) need formulas specifically validated for large breed growth due to stricter calcium limits.
Does air dried dog food need to be refrigerated?
No. The moisture removal process makes air dried food shelf-stable. Store in the original sealed bag at room temperature, away from heat and light. Once opened, follow the brand’s guidance; Ziwi Peak recommends using it within 8 weeks.
What are the best air dried dog food brands?
Ziwi Peak and Open Farm are two of the best-known complete air dried lines, and both rate well on ingredient quality and AAFCO compliance. Ziwi Peak leads on organ meat inclusion and protein density across its range, while Open Farm offers recipes labeled for large breed puppy growth.
Is air dried dog food good for dogs with sensitive stomachs?
Often yes. Limited ingredient profiles and single protein sources reduce common allergen exposure. The high digestibility of air dried protein can also mean less fermentation in the colon, which helps dogs prone to gas, loose stools, or food sensitivities.
Can senior dogs eat air dried dog food?
Healthy seniors do well on air dried food. Natural glucosamine and chondroitin from bone-inclusive formulas may support joint health. Dogs with diagnosed kidney disease need vet guidance first, as high organ meat and bone content increases phosphorus intake significantly.
Why is air dried dog food so expensive?
Ingredient quality and processing time drive the cost. Whole named meats, organ meat inclusions, and slow low-temperature drying are more resource-intensive than kibble extrusion. Per-day cost is lower than the bag price suggests due to the high caloric density requiring smaller portions.
Conclusion
Air dried dog food is one of the most practical upgrades you can make to your dog’s diet without the complexity of raw feeding.
