A decade ago, most of us were content to reward our dogs with whatever biscuit came out of a cardboard box. Today, we scan labels the way a sommelier studies a wine list—scrutinizing sourcing, production methods, and ethical impact. Enter New Zealand’s air-dried category: a quiet revolution that preserves raw nutrition without artificial preservatives while championing pasture-to-pal transparency. Among the brands accelerating this shift, Ziwi stands out for its tight supply chain, regenerative farming partnerships, and gentle 18-hour air-drying process that locks in flavor and micronutrients.
What does that mean for your treat jar in 2025? Expect shorter, cleaner ingredient panels, novel proteins for allergy-prone pups, and recyclable packaging that actually makes it through municipal sorting systems. But with more SKUs hitting global shelves every quarter, even seasoned pet parents can feel overwhelmed. This guide unpacks the science, ethics, and practical shopping tactics you need to navigate the growing Ziwi ecosystem—no marketing fluff, no hollow rankings—so you can match a New Zealand air-dried reward to your dog’s unique biology, lifestyle, and values.
Top 10 Ziwi Dog Treats
Detailed Product Reviews
1. ZIWI Dog Chews and Treats – Venison Lung & Kidney – All Natural, Air-Dried, Single Protein, Grain-Free, High-Value Treat, Snack, Reward 2.1 Ounce (Pack of 1)
Overview:
ZIWI Venison Lung & Kidney chews are ultra-premium, single-protein treats air-dried in New Zealand. Sold in a 2.1 oz pouch, they target owners who want clean, high-value rewards for training or spoiling their dogs.
What Makes It Stand Out:
The ingredient list is literally venison lung and kidney—nothing else. Ethical, free-range New Zealand deer and a gentle air-drying process keep micronutrients intact while creating a shelf-stable, high-protein snack with zero fillers, grains, or preservatives.
Value for Money:
At almost $116 per pound, these are some of the priciest treats on the market. You’re paying for purity, provenance, and palatability; whether that offsets the sticker shock depends on how much you value single-protein simplicity and training efficacy.
Strengths and Weaknesses:
Pros: hypoallergenic single protein, strong aroma equals training gold, lightweight to carry, nothing artificial, ethical sourcing.
Cons: wallet-busting cost, crumbles in pocket, small 2 oz bag vanishes fast with big dogs, intense smell may offend humans.
Bottom Line:
If budget isn’t your primary concern and you need a blockbuster reward for picky or allergy-prone dogs, keep a bag on hand. For everyday treating, rotate with cheaper options to protect both your dog’s waistline and your wallet.
2. ZIWI Peak Air-Dried Dog Food – Lamb – All Natural, High Protein, Grain Free, Limited Ingredient w/ Superfoods (16oz)
Overview:
ZIWI Peak Air-Dried Lamb is a 16 oz, all-life-stages food that doubles as kibble replacement, topper, or high-value training nibble. It combines lamb muscle, organs, bone, and New Zealand Green Mussels in a jerky-like square.
What Makes It Stand Out:
Air-drying delivers raw nutrition minus freezer space; 96% meat, organs, bone with 3% green-lipped mussel plus kelp means naturally occurring taurine, glucosamine, and antioxidants without synthetic fillers.
Value for Money:
$30 for a pound looks steep, yet each cup is 5,500 kcal/kg—small breeds need only ¼ cup per meal. Used as a mixer, the bag stretches weeks, putting real cost closer to premium canned food.
Strengths and Weaknesses:
Pros: triple-duty (meal/mixer/treat), omega-rich for skin & joints, lightweight for hiking, dogs obsess over flavor.
Cons: square pieces too large for tiny puppies, resealable strip fails after three uses, crumb dust at bottom equals waste, price prohibits exclusive feeding for giant breeds.
Bottom Line:
A fantastic topper or travel meal for discerning guardians. Feed it solo to small dogs, mix 20% into kibble for big guys, and enjoy the shiny-coat payoff without raw-food hassle.
3. ZIWI Peak Steam & Dried Dog Food – Grass-fed Beef w/Pumpkin – High Protein, Low Carb, All Breeds & Lifestages, for Digestive Health (28.8oz)
Overview:
ZIWI’s Steam & Dried Beef formula merges two gentle preservation techniques—brief steaming followed by low-temperature air-drying—to create a 28.8 oz, pumpkin-boosted, single-protein diet for all life stages.
What Makes It Stand Out:
The hybrid process kills pathogens while locking in heat-sensitive vitamins, and the addition of pumpkin, beet, chicory, and carrot fiber supports gut health without introducing extra proteins.
Value for Money:
At $18.32/lb this is the cheapest complete diet ZIWI offers. Because the kcal/kg sits slightly lower than Peak air-dried, portion sizes rise, but the bag still undercuts competitors pound-for-pound.
Strengths and Weaknesses:
Pros: easier chew texture for seniors, reduced fat suits couch-potato dogs, visible veggie specks entice picky eaters, single beef protein ideal for elimination trials.
Cons: slightly higher carb fraction vs. Peak line, bag not resealable after 1 lb mark, crumbles create “beef dust,” strong aroma clings to hands.
Bottom Line:
A smart stepping-stone into premium air-dried food for large-budget, large-dog households. Rotate with Peak or raw to manage cost while giving digestive systems a fiber-inclusive boost.
4. ZIWI Venison Deer Half Shank – 2-in-1 Dog Bone Chew Treat Wrapped in Beef Esophagus – All Natural, Air-Dried
Overview:
ZIWI Venison Half Shank is a 2-in-1 recreational chew consisting of a deer shank bone wrapped in air-dried beef esophagus. Marketed for small-to-medium power chewers, it offers extended engagement and dental abrasion.
What Makes It Stand Out:
Unlike cattle bones, deer shank is marrow-rich yet thinner, making it more appropriate for moderate jaws. The esophagus wrapping provides immediate wins, encouraging dogs to tackle the harder core while protecting teeth from direct slab fracture.
Value for Money:
Around $15 each, the chew lasts most dogs multiple sessions. Compared with single-use bully sticks, price per minute of occupation is reasonable, especially for allergy dogs needing novel proteins.
Strengths and Weaknesses:
Pros: single-protein antler alternative, high novelty reduces resource guarding, no staining smoke or odor, ethically sourced NZ venison.
Cons: small dogs may abandon once esophagus is gone; larger dogs can splinter shank after heavy gnawing—supervision mandatory; not suitable for rock-hard chewers.
Bottom Line:
Excellent enrichment for light-to-moderate chewers or as an occasional novel protein bone. Remove when the wrap is consumed and discard if splintering starts to keep the experience safe and fun.
5. Vital Essentials Beef Liver Dog Treats, 2.1 oz | Freeze-Dried Raw | Single Ingredient | Premium Quality High Protein Training Treats | Grain Free, Gluten Free, Filler Free
Overview:
Vital Essentials Beef Liver treats are freeze-dried cubes of USA-sourced beef liver packaged in a 2.1 oz resealable pouch. Marketed as single-ingredient, high-protein training bites, they’re pitched against pricier imported organs.
What Makes It Stand Out:
Rapid 45-minute freeze-lock and slow sublimation preserve Vitamin A, B-complex, iron, and natural palatability without additives, fillers, or irradiation, while the $6 price tag undercuts boutique competitors by up to 50%.
Value for Money:
At $45.64/lb, you’re still paying premium, but the liver is lightweight—two ounces yield ~70 pea-sized cubes, enough for two weeks of daily obedience sessions. Cost per reward sits below most commercial cookies.
Strengths and Weaknesses:
Pros: crumb-free cubes don’t stain pockets, USA sourcing ensures freshness, resealable pouch actually seals, breaks easily for small dogs, single protein great for elimination diets.
Cons: cubes vary 20% in size, dust settles at bottom creating “liver powder,” rich aroma may tempt counter-surfing cats, overfeeding can loosen stools.
Bottom Line:
The wallet-friendly gateway into single-protein freeze-dried training treats. Keep a pouch on hand for high-distraction environments, and use the residual powder as a food topper—zero waste, maximum tail wag.
6. ZIWI Peak Wet Dog Food Variety Pack – Beef, Chicken, Lamb, Mackerel, Tripe, Venison, 6 Pack (6oz Each)
ZIWI Peak Wet Dog Food Variety Pack
Overview: ZIWI’s 6-pack sampler delivers six moisture-rich, grain-free pâtés—beef, chicken, lamb, mackerel, tripe, and venison—each crafted from New Zealand free-range proteins and green-lipped mussels.
What Makes It Stand Out: The brand’s “whole-prey in a can” philosophy—92 % meat, organs, bone, and seafood—plus cold-washed tripe for digestive enzymes and kelp for trace minerals is unmatched in grocery-aisle wet food.
Value for Money: At $0.83/oz it’s double supermarket brands, but you’re buying air-dried-quality nutrition without the rehydration step; used as a topper, one can stretches four meals, dropping cost per serving to about $1.25.
Strengths and Weaknesses: Pro: species-appropriate macros, no fillers, all life stages, ethically sourced. Con: strong tripe aroma, mackerel formula is oil-rich for sensitive stomachs, pull-tab lids can splatter.
Bottom Line: If you feed kibble and want a convenient, biologically appropriate boost, this variety pack is the tastiest multivitamin your dog will ever lap up.
7. Stewart Single Ingredient Freeze Dried Raw Dog Treats, Beef Liver, 21 Ounce Value Size, Approx. 475 Pieces per Resealable Tub, Training Treats or Meal Topper, High Protein, Grain Free, Gluten Free
Stewart Freeze-Dried Beef Liver Treats
Overview: A 21-oz resealable tub packed with ~475 shards of USDA-certified beef liver that’s freeze-dried in Dayton, Ohio since 1973.
What Makes It Stand Out: Single-ingredient purity plus professional-trainer heritage—CNN ranked it top treat in 2024—means you’re holding the gold-standard high-value reward used by AKC handlers.
Value for Money: $35.99 sounds steep, but 475 treats break down to $0.08 each; a 3-month supply for most dogs, rivaling grocery-store jerky that’s half protein and half sugar.
Strengths and Weaknesses: Pro: crumb-free pockets, cats love crumbs, 55 % crude protein, zero allergens. Con: shards vary in size, dust settles at bottom, aroma can clear a room on humid days.
Bottom Line: For recall training or finicky eaters, nothing beats the universal canine currency of Stewart’s liver—buy once, refill never.
8. Stella & Chewy’s Freeze-Dried Raw Lamb Heart Dog Treats – Single Ingredient, No Additives – Premium Training Treats – Perfect For Picky Eaters – 3oz Bag
Stella & Chewy’s Freeze-Dried Lamb Heart Treats
Overview: Three ounces of diced, freeze-dried lamb hearts sourced and packaged in the USA for dogs that turn up their noses at ordinary biscuits.
What Makes It Stand Out: Heart tissue is naturally rich in taurine and heme iron—nutrients kibble often loses in extrusion—so you’re feeding cardiac support disguised as candy.
Value for Money: $14.99 equals $79.95/lb, but lamb heart is a specialty offal; used sparingly for training, the bag lasts a month and replaces costlier supplements.
Strengths and Weaknesses: Pro: irresistible even to picky poodles, resealable pouch keeps crunch, zero additives. Con: tiny 3-oz bag feels empty, cubes can be hard for toy breeds, strong scent clings to fingers.
Bottom Line: A pocket-sized secret weapon for reactive-dog counter-conditioning—tiny price for big behavioral gains.
9. Zuke`s Mini Naturals Dog Treat Peanut Butter 1lb
Zuke’s Mini Naturals Peanut Butter
Overview: One-pound pouch of 2-calorie soft nibbles infused with real peanut butter, cherries, and added vitamins, manufactured in Utah since 1995.
What Makes It Stand Out: Miniature size means you can deliver 50 rewards without breaking calorie budget—perfect for clicker-shaping a new trick in one walk.
Value for Money: $14.94/lb positions it mid-pack; at 500+ treats per bag you’re paying 3 ¢ per reinforcement, cheaper than string cheese and far less messy.
Strengths and Weaknesses: Pro: wheat-free, stays soft in freezing weather, resealable zipper works. Con: contains cane sugar, cherry bits can stain light fur, smell tempts counter-surfing Labradors.
Bottom Line: The classic obedience-class staple—small, smelly, and guilt-free for endless repetitions.
10. Zignature Venison Soft Moist Treats for Dogs
Zignature Venison Soft-Moist Treats
Overview: A 4-oz pouch of limited-ingredient, venison-first moist squares designed to match Zignature’s venison kibble for allergy-management programs.
What Makes It Stand Out: Exotic single-protein format bypasses common chicken/beef intolerances while maintaining soft texture senior dogs or power chewers can wolf down without crumbs.
Value for Money: $8.49 looks cheap until you notice the pouch is only 4 oz ($33.96/lb); still, for an elimination diet, it’s cheaper than prescription biscuits.
Strengths and Weaknesses: Pro: legume-free, no chicken fat, smells like jerky not medicine, breaks into smaller pieces. Con: limited stock in pet stores, can dry out if zipper isn’t sealed, darker squares occasionally overcooked.
Bottom Line: Keep a bag on hand for tummy-troubled pups—simple, soothing, and vets love the ingredient discipline.
Why Air-Dried Treats Are Dominating 2025’s Premium Aisle
Shelf-stable meats that retain raw bioavailability used to be a formulation unicorn. Twin-screw extrusion—the standard for kibble and many soft treats—subjects ingredients to extreme heat and pressure, degrading heat-labile vitamins and amino acids. Air-drying, by contrast, circulates low-temperature, humidity-controlled air across thin meat slices for up to 24 hours. Moisture drops to <14%, preventing microbial growth, yet internal temperatures rarely exceed 76 °C (169 °F). The result: pathogens are neutralized while natural enzymes, B-vitamins, and omega-3s remain largely intact. In 2025, post-pandemic supply-chain pragmatism meets consumer demand for “less processed,” propelling air-dried formats into the mainstream at a 31 % year-over-year growth rate.
The New Zealand Advantage: Pasture-Raised, Pasture-Fed
Geography doubles as quality control when your country’s stock graze on clover-rich ryegrass 365 days a year. New Zealand’s temperate maritime climate eliminates the need for grain-heavy finishing or intensive feedlots. Cattle, lamb, deer, and venison roam under strict national animal-welfare codes, translating into naturally higher intramuscular omega-3s, conjugated linoleic acid, and antioxidant trace minerals. Brands that source within the country inherit those nutritional gains by default—a terroir argument your dog can taste in every chewy morsel.
Decoding Ziwi’s Gentle Air-Drying Technology
Ziwi’s proprietary two-stage process starts with cold-air circulation to reduce surface moisture, followed by a warm-air finish that achieves a water activity (aw) level below 0.86. This dual-phase method prevents case-hardening—the formation of a tough outer shell that traps moisture inside, a common defect in single-stage dryers. The meat never reaches pasteurization temps, so Ziwi adds a controlled HPP (high-pressure processing) step for pathogen insurance, yielding the safety of cooked with the nutritional kudos of raw.
Ethical Sourcing: From Regenerative Farm to Freeze-Proof Harbor
“Free-range” is table stakes; regenerative is the new north star. By pairing long-term contracts with suppliers who practice rotational grazing, Ziwi helps restore soil microbial biomass and carbon sequestration. Sea-freight consolidation out of Timaru and Tauranga reduces shipping frequency, while insulated, refrigerant-free containers maintain product integrity below 15 °C through the equator—no environmentally taxing air freight needed. You’re not just buying treats; you’re financing lower-emission logistics.
Novel Proteins That Tackle Allergies and Sensitivities
Chicken-fat sprays and hidden turkey meals are the bane of elimination diets. Single-protein air-dried treats let you pinpoint allergens with laser precision. Consider muntjac venison (novel to most North American dogs) or green-lipped mussel for omega-3s sans fishy breath. Because Ziwi limits each recipe to meat, organs, bone, and minimal seaweed, you can isolate variables during food trials without decoding cryptic digest or flavor “by-products.”
Organ Inclusion: Nutrition Powerhouse or Hype?
Liver, kidney, and tripe aren’t budget fillers—they’re micronutrient dynamos. A 10-g venison heart medallion delivers 200 % of a 20-lb dog’s daily B12 requirement, supporting myelin sheath maintenance for senior cognition. Kidney provides natural selenium, essential for thyroid hormone conversion. Air-drying preserves these water-soluble vitamins better than baking, making organ-enhanced treats a strategic supplement for picky eaters who outsmart pill pockets.
Green-Lipped Mussel: Joint Support Straight from the Marlborough Sounds
New Zealand’s endemic mussel species (Perna canaliculus) is the planet’s richest known source of ETA (eicosatetraenoic acid), a rare omega-3 that down-regulates cyclo-oxygenase pathways responsible for joint inflammation. Ziwi adds whole mussels at 3 % inclusion—enough to yield 25–30 mg combined ETA/EPA/DHA per standard reward. Think of it as a treat-sized alternative to daily chews, ideal for athletic agility dogs or couch-potato seniors recovering from orthopedic surgery.
Bone vs. Bone-Free: Calcium Math for Home Feeders
Raw feeders already juggle phosphorus-to-calcium ratios; treats can quietly sabotage that balance. Air-dried bone-in recipes deliver approximately 1.2 % calcium on an as-fed basis—safe for intermittent rewards but potentially destabilizing if you’re tossing handfuls to a 5-lb Chihuahua. For small breeds or kidney-compromised dogs, opt for bone-free formats and account for bone content elsewhere in the daily ration.
Calorie Density & Portion Planning: Don’t Let Treats Tip the Scale
Air removal concentrates calories: 5,000–5,500 kcal/kg vs. 3,500 kcal in baked biscuits. Translate that to real life: a strip the size of your index finger equals 9 % of a 40-lb dog’s maintenance energy. Use a gram scale, not guesswork. Pre-portion daily allotments into a “treat budget” jar; once it’s empty, you’re done—no sad puppy eyes required.
Reading the Label Beyond the Brand Name
Marketing loves icons: “wild,” “peak,” “ancestral.” Flip the bag. Ingredient lists descend by weight pre-drying; if lamb tripe appears ahead of lamb meat, you’re buying mostly stomach lining—not inherently bad, just know what you’re funding. Guaranteed analysis expresses protein as a minimum; since water is missing, percentages look artificially high. Divide by 4.5 to estimate dry-matter protein if you want apples-to-apples comparisons with kibble.
Storage and Freshness: Keeping Air-Dried at Peak Quality
Ziwi’s multi-layer pouches include an EVOH oxygen barrier, but once opened, residual moisture migrates. Store below 20 °C, <60 % humidity, and squeeze excess air before resealing. For households going through less than a 280-g bag monthly, vacuum-divide into weekly portions and freeze. Contrary to myth, freezing air-dried meat does not rupture cell walls—it simply halts lipid oxidation, doubling shelf life.
Travel-Friendly Perks for Backpackers and Van-Lifers
Road warriors appreciate that air-dried treats weigh 60 % less than freeze-dried equivalents and don’t crumble into powder at high altitude. Vacuum-packed bricks survive TSA scrutiny, smell mild thanks to low moisture, and double as high-value training currency in distracting environments. Pro tip: pair with a collapsible silicone bowl; rehydrate a few pieces in creek water to create a scented food topper when your dog goes off-ration from motion stress.
Cost Breakdown: Are You Paying for Protein or Story?
New Zealand’s minimum wage, comprehensive quarantine, and regenerative programs inflate COGS (cost of goods sold). Calculate price per gram of animal protein to see if novelty is draining your wallet. Divide packet cost by net weight, then multiply by the guaranteed protein percentage (converted to dry-matter). Anything above $0.18 per gram of animal protein enters luxury territory—worthwhile if your dog suffers allergies, but overkill for resilient stomachs.
Sustainability Metrics: Carbon Pawprint of Local vs. Import
New Zealand lamb emits 14 kg CO₂-e/kg live weight—half the global average—thanks to year-round forage and lower methane genetics. Still, shipping 1 kg of finished treats to Los Angeles adds another 1.3 kg CO₂-e via sea freight. The net 1,000-g carbon surcharge equals driving 3.5 miles in an average sedan. Buying in bulk cuts per-treat emissions by 30 % and consolidates fulfillment, so consider co-op orders with training clubs.
Vet-Validated Benefits for Skin, Coat, and Cognition
In a 2023 pilot trial at Massey University, 21 atopic dogs replaced 15 % of daily calories with green-lipped mussel-enriched air-dried treats. After eight weeks, epidermal ceramides rose 18 % and pruritus scores dropped 27 %. Researchers credit ETA omega-3s plus preserved zinc from green tripe. Likewise, DHA-rich fish variants improved reversal-learning tasks in a canine cognitive-battery test, hinting at neuroprotective upside for senior pets.
Transition Tips: Introducing Air-Dried Without Gastro Upset
Sudden leaps from extruded treats to 50 % rich organs can trigger osmotic diarrhea. Use a 14-day switch: start with 10 % new treat volume and escalate in 10 % increments every 48 hours. Pair with a canine-specific probiotic containing Enterococcus faecium to buffer gut flora shifts. If stools loosen, park at the last tolerated ratio for one week before advancing.
Frequently Asked Questions
1. Are Ziwi air-dried treats complete and balanced for all life stages?
No. They are formulated as complementary snacks; feed ≤10 % of daily calories unless directed otherwise by a veterinary nutritionist.
2. Can puppies under six months eat air-dried rewards?
Yes, but crumble into pea-sized pieces to avoid choking and subtract equal calories from meals to prevent rapid growth spurts.
3. Do these treats require refrigeration after opening?
Refrigeration isn’t mandatory if used within eight weeks, but cooler storage extends flavor and slows lipid oxidation.
4. How do I verify authentic New Zealand sourcing?
Look for the “Made in New Zealand” statement plus MPI (Ministry for Primary Industries) export certification code printed on the back panel.
5. Is air-dried safer than raw for immunocompromised dogs?
Yes—low water activity plus HPP reduces pathogen load, but consult your vet if your dog is on chemotherapy or anti-rejection drugs.
6. Will the rich organ content cause vitamin A toxicity?
Hypervitaminosis A is unlikely when treats stay under 10 % of daily calories; beyond that, monitor total liver intake across all foods.
7. Are these treats ok for dogs with pancreatitis?
Choose the lowest-fat fish or venison options and confirm with your vet; fat hovers around 10–12 %, still too high for some pancreatitis cases.
8. Can I rehydrate air-dried pieces for a senior with dental issues?
Absolutely—cover with warm water for 3–4 minutes; texture softens to a pâté-like consistency without leaching nutrients.
9. Why do colors vary between batches?
Natural pasture fluctuations, seasonal animal diet, and gentle drying temperatures create hue shifts; they don’t indicate spoilage.
10. Is Ziwi packaging recyclable in the US?
The outer pouch is a #7 multi-layer; check with TerraCycle’s pet-food free program or store drop-off locations that accept flexible plastics.
