Raw dog food divides the pet nutrition world more than almost any other topic. Advocates credit it with improved coat condition, reduced allergies, better digestion, and cleaner teeth. Critics point to bacterial contamination risks, nutritional imbalance, and a lack of controlled feeding trials. The truth, as usual, sits between the extremes. Raw feeding done correctly, with quality sourcing and proper safe handling, is a legitimate feeding option for healthy adult dogs. Raw feeding done wrong — and five specific mistakes account for most of the failures — creates real health risks for both dogs and humans. This guide tells you exactly what you need to know before you start.
Raw dog food consists of uncooked muscle meat, organ meat, raw meaty bones, and optionally raw fruits and vegetables. The two main approaches are BARF (Biologically Appropriate Raw Food) and Prey Model Raw (PMR). Done correctly with nutritional balance, safe handling, and quality sourcing, it can be a healthy diet for adult dogs. The five most common beginner mistakes are: no calcium source, inadequate organ ratio, unsafe food handling, wrong protein percentages, and ignoring individual dog health status.
Understanding Raw Dog Food — The Two Main Approaches
BARF — Biologically Appropriate Raw Food
The BARF model, popularised by Dr. Ian Billinghurst, includes:
- 70% raw muscle meat
- 10% raw edible bone
- 10% organ meat (5% liver, 5% other secreting organs)
- 10% vegetables, fruits, and supplements (including eggs, dairy, kelp)
BARF is considered more forgiving for beginners because the vegetable and supplement component helps fill nutritional gaps that can occur in a pure meat diet.
PMR — Prey Model Raw
Prey Model Raw attempts to replicate the whole-prey diet of a wild canid more closely:
- 80% raw muscle meat
- 10% raw edible bone
- 10% organ meat (5% liver, 5% other secreting organs)
- No fruits, vegetables, or supplements in the core model
PMR is considered more biologically aligned but more demanding to balance correctly without significant feeding knowledge.
The 5 Most Common Beginner Mistakes
Mistake 1 — No Calcium Source (The Most Dangerous Error)
This is the mistake that causes the most serious harm. Muscle meat contains almost no calcium. If you feed raw muscle meat without an adequate calcium source, your dog develops a calcium-phosphorus imbalance that leads to metabolic bone disease — particularly in growing puppies, where the consequences can be rapid and severe.
The solution: raw edible bones (not cooked — cooked bones splinter and are dangerous) provide the calcium source in a raw diet. Common edible bones:
- Chicken wings, drumsticks, thighs, backs, necks
- Duck wings and necks
- Rabbit (whole or sections)
- Turkey necks
If a dog cannot eat raw bones (due to dental issues, aggression around bones, or risk of aspiration), ground bone or bone meal must be substituted at the correct ratio. This is not optional — it is the most critical aspect of raw diet balance.
- Safe bone protocol: always supervise feeding of raw bones. Remove any piece that becomes small enough to swallow whole. Never feed cooked, smoked, or dehydrated weight-bearing bones (femurs, knuckle bones) — these cause tooth fractures.
Mistake 2 — Incorrect Organ Ratios
Many beginners over-feed liver. Liver is nutritionally extremely dense — it is the primary source of vitamin A in a raw diet — and feeding too much causes vitamin A toxicity (hypervitaminosis A), which presents as bone pain, joint problems, and in chronic cases, serious liver damage.
Correct ratio: no more than 5% of the total diet as liver. The remaining 5% secreting organ should be a different organ — kidney, spleen, testicle, or pancreas.
- Feed liver maximum twice per week in small amounts — not daily in large portions
- If the dog has loose stools after adding organ meat, reduce to once weekly and increase gradually
Mistake 3 — Unsafe Food Handling
Raw meat carries Salmonella, Listeria, E. coli, and Campylobacter. Healthy adult dogs handle these pathogens well due to their highly acidic stomach environment and short GI tract. Humans — particularly immunocompromised individuals, pregnant women, the elderly, and children — do not have this biological protection.
| Action | Why It Matters |
|---|---|
| Wash hands with soap for 20 seconds before and after handling | Cross-contamination to human food surfaces |
| Thaw raw food in the refrigerator, not on the counter | Counter thawing multiplies bacterial count rapidly |
| Use separate cutting boards (colour-code them) | Prevents cross-contamination with human food prep |
| Clean food bowls daily with hot water and dish soap | Bacterial biofilm builds rapidly in protein-residue bowls |
| Store raw food in sealed containers in the refrigerator for max 3 days | Time + moisture = bacterial growth |
| Freeze raw food in meal-sized portions | Prevents over-handling of large quantities |
| Do not allow the dog to lick faces after eating | Direct transmission route for pathogens |
Mistake 4 — Single-Protein Feeding for Too Long
Beginners often start with one protein (typically chicken) and stay with it for months because the dog likes it and the owner has found a supplier. Single-protein feeding over a long period:
- Fails to provide the nutritional variety that balances the diet across different amino acid, fat, and micronutrient profiles
- Increases the risk of developing a sensitivity or intolerance to that specific protein
- Often results in deficiencies in nutrients present in other protein sources (e.g., fish provides omega-3s that chicken lacks)
The target: rotate through at least 3–4 protein sources regularly. Common protocol is to rotate weekly or bi-weekly:
- Poultry (chicken, turkey, duck)
- Red meat (beef, lamb, pork)
- Fish (salmon, sardines, mackerel — whole or boneless)
- Novel proteins (venison, rabbit, goat) — particularly useful for dogs with sensitivities
Mistake 5 — Feeding Raw to the Wrong Dog
Raw feeding is not appropriate for all dogs. Dogs for whom raw feeding requires extra caution or is not recommended:
- Puppies under 12 weeks — the immune system is immature; pathogen risk is higher; nutritional requirements are more exacting and harder to meet with DIY raw during rapid growth phases. Wait until 12 weeks minimum; many raw feeders start at 16–20 weeks with veterinary guidance.
- Dogs with confirmed immune disorders — immunosuppression increases susceptibility to foodborne pathogens dramatically
- Dogs with pancreatitis history — raw diets tend to be high fat; high-fat feeding can trigger or worsen pancreatitis
- Post-surgery or illness recovery — compromised immune function during recovery
- Senior dogs with significant renal decline — high protein increases filtration demand on compromised kidneys; consult a vet with bloodwork first
Nutritional Completeness — Do You Need Supplements?
Short answer: most home-prepared raw diets, even when correctly portioned with bone and organ, benefit from targeted supplementation to ensure nutritional completeness. The most commonly needed supplements:
| Supplement | Why Needed | Dose Guidance |
|---|---|---|
| Fish oil (omega-3) | Most land-based proteins are low in omega-3 fatty acids | 20mg EPA+DHA per lb body weight daily; use within 90 days of opening |
| Vitamin E | Antioxidant that protects fats from oxidation in the body; omega-3 supplementation increases the need for it | ~1–2 IU per lb body weight (consult vet for exact dosing) |
| Iodine (kelp or iodine supplement) | Raw meat and vegetables do not provide adequate iodine for thyroid function | 1/16 tsp kelp powder per 25 lbs body weight |
| Zinc | Particularly important for breeds with zinc metabolism issues (see our Husky Care 101 guide for breed-specific zinc needs) | Only supplement if confirmed deficient — excess zinc is toxic |
| Vitamin D | Absent or very low in most raw meat except some organ meats | Include grass-fed liver and egg yolks; supplement only if vet-confirmed deficient |
Note: if using a commercial raw or freeze-dried complete diet labelled AAFCO-compliant, most supplementation needs are already met. See our comparison of Freeze-Dried Pet Food: Pros, Cons & Brand Comparison if you are choosing between DIY raw and commercially prepared raw options.
Transitioning Your Dog to Raw — The Step-by-Step Protocol
A sudden switch from kibble to raw causes digestive upset in most dogs. The gut microbiome shifts dramatically when the food type changes. Allow 10–14 days:
- Days 1–3: 80% current food, 20% raw
- Days 4–6: 60% current food, 40% raw
- Days 7–9: 40% current food, 60% raw
- Days 10–14: 20% current food, 80% raw → then 100% raw
Watch for: very loose stools, vomiting, prolonged constipation (bone content can firm stools significantly — some firmness is normal), or complete food refusal.
The “bone whitening” stool change
When feeding raw bones, your dog’s stools will often be smaller, firmer, lighter in colour, and crumble when dry. This is normal — it is the result of calcium being excreted. Completely white, very hard stools that your dog strains to pass = too much bone in the diet. Reduce bone percentage slightly.
Sourcing Quality Raw Food
Commercial raw (frozen or freeze-dried) vs DIY
Commercial raw options (frozen patties, freeze-dried complete diets) are the most beginner-friendly entry point. The nutritional balance has been done for you. Look for:
- AAFCO or NRC nutritional adequacy statement on the label
- Clear breakdown of meat/bone/organ percentages on the packaging
- Named protein sources (chicken, beef — not “poultry” or “meat”)
DIY raw is cheaper per serving but demands significantly more nutritional knowledge. If building a DIY diet, use a vetted raw feeding calculator or work with a veterinary nutritionist (board-certified) to formulate a complete diet. Generic online “80/10/10 ratios” are a starting framework, not a complete guarantee of nutritional adequacy.
Human-grade meat vs pet-grade
Human-grade meat from a butcher or supermarket is generally equivalent or superior to pet-grade meat for safety. Pet-grade “green tripe” (raw unbleached stomach lining) is not available as human-grade — it is a valuable raw ingredient with high probiotic content and distinct from bleached white tripe sold in supermarkets.
Frequently Asked Questions
Is raw dog food better than kibble?
Neither is universally superior. High-quality kibble that is AAFCO-complete, protein-first, and free of excessive fillers is a nutritionally adequate diet for the majority of dogs. Raw feeding, done correctly, may offer benefits for specific dogs — particularly those with food sensitivities, certain inflammatory conditions, or poor responses to processed ingredients. “Better” depends on the individual dog, the quality of the specific products compared, and how correctly the raw diet is balanced.
Can raw feeding cause aggression?
No — this is a widespread myth. Aggression is caused by genetics, socialisation, training history, and pain — not by protein type or raw feeding. A dog that guards its raw food bowl is displaying resource guarding behaviour, which is a training issue that exists regardless of what is in the bowl. Address resource guarding with a professional trainer.
Can I feed raw and kibble in the same meal?
The old belief that you cannot mix raw and kibble in the same meal (based on the idea that they digest at different rates) has been largely debunked. Dogs’ digestive systems handle mixed food types well. You can feed raw and kibble in the same bowl if you prefer. However, the two foods do not need to be mixed — feeding one at one meal and one at another works equally well.
How do I know if my raw diet is balanced?
The most reliable method is to have the diet formally reviewed by a board-certified veterinary nutritionist (DACVN). Short of that, using an established commercial raw brand with an AAFCO statement is the safest route. Annual bloodwork (CBC, chemistry panel, vitamin D, B12, and folate) allows you to catch developing deficiencies before they cause clinical problems.
