Is ZIWI Peak or The Honest Kitchen better for dogs?

Effectively tied at A/90 vs A/90 on the v15 rubric. ZIWI Peak Venison Recipe Air-Dried Dog Food leads with 96% New Zealand free-range venison + organ meats + green-lipped mussel for joint support, AAFCO all life stages including large-breed puppy, and shelf-stable air-dried feed-as-is format. The Honest Kitchen Wholemade Whole Grain Chicken leads with USDA human-grade facility production with full human-food-supplier traceability, grain-inclusive formulation that avoids the FDA grain-free DCM watchlist, and rehydrated-stew format for high-moisture appetite-stimulating meal feeding. Pick ZIWI Peak for novel-protein venison and shelf-stable convenience. Pick The Honest Kitchen for human-grade certification and grain-inclusive structure.

What is the difference between air-dried (ZIWI) and dehydrated (Honest Kitchen)?

Both are low-temperature moisture-removal processes that preserve more nutritional structure than extrusion-stage thermal processing, but the formats and feeding methods are different. Air-drying (ZIWI Peak) uses gentle airflow at low temperature (101-115°F over a 3-4 day cycle) to remove moisture while preserving the cellular structure of the meat and organ ingredients. The result is a shelf-stable jerky-like morsel that can be fed as-is or mixed into other food. Dehydration (Honest Kitchen) uses similar low-temperature methodology to remove moisture but produces a flake or powder format designed to be rehydrated with water 1:1 before serving (creating a stew-like meal). Both methods preserve more heat-sensitive nutrients than extruded kibble (250°F+). The choice depends on whether you want shelf-stable feed-as-is convenience (air-dried) or high-moisture rehydrated meal-feeding (dehydrated).

Is grain-free or grain-inclusive better for my dog?

It depends on the breed and individual health profile. The FDA’s 2018-2022 investigation into a potential association between grain-free formulations and DCM (dilated cardiomyopathy) flagged grain-free formulations using pulses (peas, lentils, chickpeas) as the primary carbohydrate source as a structural concern, particularly for breeds with elevated DCM risk (Doberman Pinschers, Golden Retrievers, Great Danes, Boxers, Cocker Spaniels). The FDA closed active investigation in 2022 without a definitive causal mechanism identified, but many veterinary cardiologists continue to recommend grain-inclusive formulations for DCM-risk breeds. ZIWI Peak Venison is grain-free but is also extremely high-meat / low-pulse (the formula uses minimal plant-source carbohydrate substitutes) — structurally distinct from the kibble-style grain-free formulations the FDA scrutinized. The Honest Kitchen Wholemade is grain-inclusive (organic barley + organic oats), which avoids the FDA-monitored formulation pattern entirely. For dogs with DCM-risk-breed status, grain-inclusive picks like THK Wholemade are the structurally cautious choice. For dogs without DCM-risk-breed status and owners preferring high-meat low-carb formulation, ZIWI Peak Venison is structurally aligned.

The short answer: Effectively tied at A/90 vs A/90 on the v15 rubric. Both are A-tier minimally-processed dog foods from independent (non-conglomerate) brands, but built around different formats and protein structures. ZIWI Peak Venison Recipe Air-Dried Dog Food is 96% New Zealand free-range venison + venison organ meats + green-lipped mussel, air-dried at low temperature (no extrusion), AAFCO all life stages including large-breed puppy. The Honest Kitchen Wholemade Whole Grain Chicken is human-grade dehydrated chicken + whole grains (organic barley + organic oats + organic flax) produced in a US human-food-grade facility. ZIWI is shelf-stable air-dried as-is; THK Wholemade requires water rehydration (1:1 ratio). Pick on protein (novel-protein venison vs chicken), format (air-dried as-is vs dehydrated + water), and ingredient philosophy (96% meat-organ vs human-grade whole-food + grains).

The scores

ZIWI Peak Venison Recipe Air-Dried Dog Food: A (90/100) — Venison, Venison Tripe, Venison Heart, Venison Lung, Venison Liver.

How the ingredients compare

The top-five ingredients reveal the formulation split between these two products:

ZIWI Peak: Venison, Venison Tripe, Venison Heart, Venison Lung, Venison Liver

The Honest Kitchen: Dehydrated Chicken, Organic Barley, Potatoes, Organic Flax, Organic Oats

Both products earn effectively the same v15 score, but the ingredient lineups tell different stories about how they got there — that is where the actual pick decision lives.

Where ZIWI Peak pulls ahead

96% New Zealand free-range venison + organ meats + green-lipped mussel + AAFCO large-breed puppy: ZIWI Peak Venison Recipe leads with venison, venison tripe, venison heart, venison lung, venison liver, and venison bone — with green-lipped mussel for omega-3 EPA + DHA. The 96% meat-organ density is among the highest in commercial dry-format dog food. New Zealand free-range venison is naturally grass-fed with no antibiotic or hormone supplementation (New Zealand farming regulations prohibit growth hormones in livestock production by default). The recipe is AAFCO-substantiated for all life stages including large-breed puppy growth (a stricter calcium and phosphorus ratio bar that many grain-free formulations don’t meet). For owners specifically wanting maximum meat-organ density in a shelf-stable dry format with novel-protein venison and large-breed-puppy substantiation, ZIWI Peak is the structurally aligned pick.

Novel-protein venison for elimination-diet utility + green-lipped mussel for joint support: Venison is a novel protein for most US dogs — no prior immunologic exposure for dogs raised on chicken / beef / turkey / lamb based commercial kibble. For dogs with suspected food allergies or food sensitivities, novel-protein elimination-diet feeding trials commonly use venison as the test protein. THK Wholemade Whole Grain Chicken uses chicken, which is in the top-6 food-allergy triggers for dogs. Additionally, ZIWI’s green-lipped mussel inclusion supplies natural EPA + DHA omega-3 + glycosaminoglycans (glucosamine + chondroitin + hyaluronic acid) for joint support — the species-specific marine omega-3 + GAGs are structurally distinct supplementation. For owners specifically running elimination-diet feeding trials or wanting whole-food joint-support inclusion, ZIWI Peak is the structurally aligned pick.

Shelf-stable air-dried format requires no rehydration or refrigeration: ZIWI Peak is air-dried at low temperature (101-115°F over a 4-day cycle) which removes moisture without extrusion-stage thermal damage. The product is shelf-stable for ~18 months unopened, requires no rehydration before serving (feed as-is or mixed into kibble as a topper), and travels easily. THK Wholemade is dehydrated and requires 1:1 water rehydration before feeding (the powder must be reconstituted to a stew-like consistency 3-5 minutes before serving). For households without consistent ability to manage rehydration prep (busy mornings, travel, kennels), ZIWI Peak’s feed-as-is format is the structurally aligned pick. For owners specifically wanting the moisture-content of a rehydrated meal, THK Wholemade is structurally aligned (see B-side).

Where The Honest Kitchen holds its own

USDA human-grade certification + human-food-grade facility production: The Honest Kitchen produces all of its products in a US facility that meets USDA human-food-grade standards — meaning the same hygiene, ingredient-sourcing, traceability, and inspection standards as a human-food production facility. This is structurally distinct from standard pet-food-grade production, which operates under different (less stringent) regulatory requirements. ZIWI Peak is produced in New Zealand under New Zealand’s pet-food regulatory framework (high standards, but distinct from US human-food-grade certification). For owners specifically prioritizing US human-food-grade facility production and the supply-chain transparency that comes with it (every ingredient traceable to a USDA-inspected human-food supplier), The Honest Kitchen is structurally aligned.

Whole grains + organic flax for grain-inclusive AAFCO substantiation + grain-free DCM-watchlist avoidance: THK Wholemade includes dehydrated chicken + organic barley + potatoes + organic flax + organic oats — a grain-inclusive formulation that sidesteps the FDA’s 2018-2022 grain-free DCM (dilated cardiomyopathy) watchlist concerns. Organic flax supplies plant-source ALA omega-3 (with the caveat that dog ALA-to-EPA conversion is limited). ZIWI Peak is grain-free (no grains in the formulation) — structurally fine for dogs without DCM-risk-breed status but not the preferred structure for breeds with elevated DCM risk (Doberman Pinschers, Golden Retrievers, Great Danes, Boxers, Cocker Spaniels). For owners with DCM-risk-breed dogs or who prefer grain-inclusive formulation philosophy, THK Wholemade Whole Grain is the structurally aligned pick.

Rehydrated stew format delivers high moisture content + appetite stimulation: THK Wholemade rehydrates 1:1 with water to a warm stew-like consistency — the moisture content of the served meal is similar to wet/canned food (~70-75% moisture by weight after rehydration). This benefits dogs with reduced kibble appetite (picky eaters, post-surgery recovery, senior dogs with dental issues, or dogs with chronic UTI or kidney concerns where higher dietary moisture is recommended). The warm stew temperature and aromatic profile typically stimulate appetite better than dry kibble or air-dried morsels. For owners specifically needing high-moisture meal feeding (without going full-canned or full-fresh), THK Wholemade’s dehydrated-stew format is the structurally aligned pick.

The bottom line

Effectively tied at A/90 vs A/90 — the pick comes down to format, protein, and processing-philosophy. Pick ZIWI Peak Venison for 96% New Zealand free-range venison + organ meats + green-lipped mussel density, novel-protein venison for elimination-diet utility, AAFCO large-breed-puppy substantiation, and shelf-stable air-dried feed-as-is format (no rehydration prep required). Pick The Honest Kitchen Wholemade Whole Grain Chicken for USDA human-grade facility production with USDA-inspected human-food-supplier traceability, grain-inclusive formulation that sidesteps the FDA grain-free DCM watchlist, and rehydrated-stew format for high-moisture appetite-stimulating meal-feeding (particularly useful for picky eaters, senior dogs with reduced appetite, or moisture-sensitive health conditions). Both are A-tier minimally-processed independent-brand picks.
