Instinct Dog Food: Raw Nutrition Review, Line Breakdown, and Feeding Guide

Brand Overview and Philosophy

Instinct is a brand owned by Nature’s Variety, a company founded in Lincoln, Nebraska with a straightforward founding thesis: dogs are carnivores descended from wolves, and raw meat-based diets most closely mirror what their digestive systems evolved to process. The brand launched in the early 2000s and has since grown into the largest dedicated raw pet food brand in North America, now distributed through Petco, PetSmart, and independent pet retailers.

The brand’s philosophy rests on three pillars: raw, real, and right. Raw refers to the use of minimally processed animal ingredients – freeze-dried, frozen, or cold-pressured rather than cooked at high temperatures. Real refers to ingredient transparency – no by-product meals, no artificial preservatives, no food dyes. Right refers to nutritional completeness – every product that carries an AAFCO nutritional adequacy statement has been formulated to meet recognised standards for either adult maintenance or all life stages including growth and reproduction.

What distinguishes Instinct from most premium dog food brands is its genuine commitment to the raw-first format rather than using “raw” as marketing language. Their flagship Raw Freeze-Dried and Raw Frozen Patty lines are among the very few commercially available raw dog foods that have undergone High Pressure Processing (HPP) – a pathogen reduction technology that uses extreme water pressure rather than heat to eliminate bacteria like Salmonella and Listeria without denaturing proteins or destroying enzymes. This positions Instinct between the household convenience of kibble and the purity of home-prepared raw diets.

The brand sits firmly in the premium price bracket. A pound of Instinct Raw Freeze-Dried typically costs four to five times the price of equivalent-weight standard kibble. However, the relevant comparison is not pound-for-pound but calorie-for-calorie and digestibility-corrected – freeze-dried raw is calorie-dense and highly digestible, so feeding quantities are considerably smaller than kibble equivalents.

Full Product Line Breakdown

Instinct produces seven distinct product lines, each targeting a different segment of the raw-feeding spectrum from full-raw devotees to kibble feeders who want to add raw nutrition without overhauling their feeding routine.

Limited Ingredient Lines

Instinct also produces a Limited Ingredient Diet (LID) sub-line under the “Limited Ingredient Diet Real Salmon Recipe” format. These feature a single animal protein and minimal other ingredients, designed for dogs with confirmed food sensitivities. The LID lines are available in freeze-dried, kibble, and wet food formats. They are certified grain-free and contain no chicken by-product meal, corn, wheat, soy, dairy, or eggs in the formulations marketed as single-protein.

Puppy-Specific Lines

Instinct produces puppy formulations under the Raw Boost Puppy and Be Natural Puppy banners. These are nutritionally distinct from adult formulas in that they carry AAFCO nutritional adequacy statements for “growth and reproduction” (which covers puppies and pregnant or nursing females) rather than “adult maintenance.” Key differences include higher calcium and phosphorus levels calibrated for skeletal development, and higher DHA content from herring oil to support brain and eye development in the first weeks and months of life.

Ingredient Analysis: What’s Inside

Taking Instinct Original Raw Bites Chicken Recipe as the benchmark formulation, the ingredient list reads: Chicken, Turkey, Chicken Liver, Cage-Free Eggs, Ground Chicken Bone, Chicken Heart, Kale, Carrots, Apples, Pumpkinseeds, Montmorillonite Clay, Dried Kelp, Cod Liver Oil, Inulin, Chia Seeds, Parsley, Blueberries, Pumpkin, Artichokes, Rosemary, Vitamin E Supplement, Zinc Proteinate, Iron Proteinate, Niacin, Vitamin A Supplement, Manganese Proteinate, Calcium Pantothenate, Riboflavin, Vitamin B12 Supplement, Folic Acid, Vitamin D3 Supplement.

• Excellent
  Chicken (first ingredient)
  Named fresh meat as the first ingredient by weight. Before dehydration, chicken contains roughly 70% water. After freeze-drying, it becomes a concentrated protein source. The species is identified (not generic “poultry”) which allows for allergen tracking.
• Excellent
  Chicken Liver
  Organ meat is a nutrient powerhouse – exceptionally rich in B vitamins, vitamin A, iron, copper, and taurine. In raw diets, liver should constitute no more than 5-10% of total diet to avoid vitamin A toxicity, and Instinct’s formulation respects this ratio.
• Excellent
  Cage-Free Eggs
  Whole egg is considered one of the most bioavailable protein sources available. The egg white contains avidin, which binds biotin when raw, but HPP processing partially addresses this concern. Eggs also provide arachidonic acid, a fatty acid dogs cannot synthesise.
• Excellent
  Ground Chicken Bone
  The ground bone component provides the calcium and phosphorus that balances the high phosphorus in muscle meat. This is the BARF diet (Biologically Appropriate Raw Food) principle applied commercially. The grinding makes bone safe – it is not whole bone that could splinter.
• Excellent
  Chicken Heart
  Cardiac muscle meat is exceptionally rich in taurine – the amino acid associated with heart health in dogs. This is particularly significant following discussions around grain-free diets and dilated cardiomyopathy (DCM): heart meat provides taurine directly.
• Moderate
  Montmorillonite Clay
  A naturally occurring mineral clay used as a natural anticaking agent and to bind mycotoxins (mould toxins) in the gut. Generally regarded as safe at the low levels used in pet food, though some pet owners prefer to avoid mineral additives.
• Excellent
  Cod Liver Oil
  Rich in EPA and DHA omega-3 fatty acids plus natural vitamins A and D. Supports coat quality, joint health, and immune function. More bioavailable than plant-based ALA omega-3 sources.
• Good
  Vegetables and Fruits (Kale, Carrots, Apples, Blueberries)
  Small-quantity plant ingredients that contribute antioxidants, fibre, and micronutrients. Dogs have limited ability to utilise plant nutrients compared to humans, but these ingredients are not harmful and may offer some benefit, particularly fibre for gut health.
• Note
  Vitamin D3 Supplement
  Vitamin D3 supplementation is necessary because fresh meat is low in vitamin D. The supplement form is safe and necessary – but note that vitamin D toxicity has been associated with errors in pet food supplementation (though no such recalls have affected Instinct to date).

Nutritional Profiles by Line

Comparing guaranteed analysis across Instinct lines on a dry matter basis (removing moisture for a fair comparison) reveals significant differences. The full raw lines deliver dramatically higher protein and fat than conventional kibble, with very low carbohydrate content – more closely matching a wolf’s natural macronutrient intake of approximately 50% protein, 45% fat, and 5% carbohydrate on a caloric basis.

Raw Freeze-Dried Chicken Recipe (Dry Matter Basis)

Raw Boost Kibble Chicken Recipe (Dry Matter Basis)

The carbohydrate figure is estimated using the standard formula: 100% minus protein% minus fat% minus moisture% minus ash% minus fibre%. Even the Raw Boost Kibble carries substantially higher carbohydrates than the full raw lines because extrusion (the process of pressure-cooking kibble into pellets) requires starch as a binder. The freeze-dried and frozen formats contain no starch binders and therefore achieve the very low carbohydrate content that proponents of biologically appropriate raw food (BARF) diets prioritise.

The Science Behind Raw Feeding

The raw feeding movement draws on the hypothesis that domestic dogs, whose digestive systems diverged from wolves only 15,000 years ago (a short time in evolutionary terms), are better adapted to the diet their ancestors ate than to the grain-based diets that commercial kibble introduced in the mid-20th century. This hypothesis is intuitive but requires scrutiny.

What the Research Actually Shows

Published veterinary research on raw diets is limited in scope and often methodologically constrained. The most robust peer-reviewed findings to date suggest the following. Raw diets typically show higher apparent digestibility for protein and fat compared to extruded kibble, meaning a higher proportion of nutrients are absorbed rather than excreted. One study published in the Journal of Animal Physiology and Animal Nutrition found that dogs on raw diets showed higher ileal digestibility of nitrogen, fat, and organic matter than dogs on extruded food with equivalent ingredient composition.

On the other hand, raw feeding carries documented pathogen risks. Multiple studies have found Salmonella contamination rates of 20-48% in commercially available raw pet foods. Dogs are generally resistant to Salmonella at the gut level, but they can shed the bacteria in their faeces, creating a zoonotic risk (transmissible to humans) particularly for immunocompromised people or households with young children. HPP processing, as used by Instinct, significantly reduces but does not completely eliminate this risk.

The DCM (dilated cardiomyopathy) scare of the late 2010s complicated the raw food conversation. The FDA investigated a possible link between grain-free diets and DCM, with early signals pointing toward legume-heavy grain-free kibbles. Subsequent research has complicated the picture considerably – the association may relate to taurine precursor bioavailability rather than the grain-free designation itself. Instinct’s raw-heavy lines, which contain high levels of heart meat (a direct taurine source), arguably represent a lower DCM risk than grain-free legume-heavy kibbles, though this comparison has not been directly studied in controlled trials.

Veterinary Consensus

The British Veterinary Association (BVA) and the American Veterinary Medical Association (AVMA) both advise against raw feeding on public health grounds, primarily citing zoonotic pathogen risk. This position reflects genuine concern about Salmonella and Listeria transmission rather than scepticism about the nutritional merits of raw protein itself. Many veterinary nutritionists take a more nuanced position: they acknowledge that commercially prepared HPP-processed raw foods like Instinct represent a substantially lower risk profile than home-prepared raw diets, and that the nutritional quality of the food is genuinely high.

Who Should Buy Instinct Dog Food

Feeding Guide and Transition Tips

Transitioning a dog from kibble to any raw or raw-inclusive diet requires a measured approach. Dogs have varying gut microbiome compositions, and a rapid dietary shift can cause digestive upset – loose stool, flatulence, or vomiting – that is not a sign the diet is wrong but simply reflects the gut’s adjustment period.

The 10-Day Transition Protocol

Days 1-3: 75% current food, 25% Instinct. Days 4-6: 50% current food, 50% Instinct. Days 7-9: 25% current food, 75% Instinct. Day 10 onwards: 100% Instinct. For dogs with sensitive stomachs, extend each phase to 5 days rather than 3. If loose stool appears, slow the transition rather than abandoning it.

For Raw Boost Mixers or Toppers used over existing food, no transition protocol is necessary – simply start with a small sprinkle and increase to the recommended amount over 3-5 days.

Rehydrating Freeze-Dried Raw

The freeze-dried complete meal lines are designed to be rehydrated before serving. Add one part dry product to one to one-and-a-half parts warm (not hot) water, allow to absorb for 1-2 minutes, then serve. The rehydration step restores the moisture that is naturally present in raw meat, improving palatability and ensuring proper hydration, particularly important for dogs that drink little water independently. Do not use boiling water – temperatures above approximately 60°C begin to denature proteins and destroy heat-sensitive vitamins.

Safe Handling for Raw Frozen Formats

Thaw Raw Frozen Patties and Minced Raw in the refrigerator, not on the counter. Thawing at room temperature allows bacterial growth on the outer surface while the interior remains frozen. Refrigerator thawing takes 12-24 hours for a standard patty. Once thawed, use within 3-4 days or refreeze immediately if unused. Always wash hands, utensils, and bowls in hot water after handling raw pet food, and use a dedicated board and knife that does not cross-use with human food preparation.
