Raw feeding is argued about more than almost anything else in dog nutrition, and the argument usually collapses three separate questions into one: is it nutritionally adequate, is it microbiologically safe, and does it improve health? Evidence for any one of those does not carry over to the others.
The part most often missed entirely is that the infection question is not only about your dog. It is about everyone who lives with your dog.
How we label our evidence
- Source-supportedStated directly in the cited institutional publication.
- Our editorial guidanceA conservative reading of the evidence applied to a caregiver decision. Not a validated clinical protocol.
- Evidence gapWe could not verify this in our approved sources, so we have not invented a number.
What counts as raw
More than frozen meat. Raw exposure also comes from dried and freeze-dried treats, toppers, and raw-coated kibble — a product does not have to look like fresh meat. Cornell notes that freeze-drying does not have the pathogen-killing effect of cooking.
Our editorial guidance
So when you review exposure — your own or with a vet — go through every animal-derived treat and topper, not just the main meal.
Where the institutions stand
Source-supported
WSAVA's Global Nutrition Committee recommends against raw meat-based diets for dogs and cats, weighing documented risks against an absence of properly documented health benefits. AAHA's 2021 nutrition guideline likewise does not endorse raw or dehydrated, non-sterilised animal foods, including treats.
Our editorial guidance
That is a risk-benefit recommendation. It does not mean every dog fed raw will become ill, and we're not going to pretend otherwise — but it does mean the burden of showing benefit has not been met.
Four risks, four different explanations
| Risk | What the sources support |
|---|---|
| Contamination and silent shedding | Bacteria or protozoa can pass from raw food to pets, people, or other animals. A dog can shed Salmonella without appearing sick. Good appetite and normal stools do not demonstrate microbiological safety. |
| Nutritional imbalance | A poorly formulated homemade diet — raw or cooked — can carry deficiencies or excesses. More meat, or a wider collection of organs, does not make a ration balanced. |
| Antimicrobial resistance | Raw foods can introduce resistant bacteria, a concern that outlasts any single episode of gastrointestinal illness. |
| Bones | Hard bones can fracture teeth. Swallowed bones or fragments can obstruct or perforate the digestive tract. |
Evidence gap
These sources describe hazards. They do not give a current probability of illness for any specific product or household, and we are not going to invent one.
The claims supporters make
| Claim | How it stands |
|---|---|
| "It's more natural." | WSAVA rejects naturalness as evidence of health benefit. |
| "It's more digestible." | WSAVA notes potential digestibility advantages for homemade diets — both raw and cooked. That does not establish a benefit unique to rawness. |
| "The coat, stools and energy improved." | Worth documenting the whole dietary change. A causal benefit from rawness itself is not verified here — ingredients, energy, fat, fibre and other care all changed at the same time. |
| "It prevents disease and extends life." | Not verified in the institutional material reviewed. This isn't a systematic appraisal of every primary study, so it also isn't a claim that no benefit could ever be shown. |
The household question
Source-supported
AAHA identifies very young, older, and immunocompromised people as particularly vulnerable, and specifically discourages raw feeding for therapy animals in animal-assisted interventions. Exposure can come from the food, the animal, faeces, or contaminated surfaces. WSAVA additionally highlights pregnant people and parasites including Toxoplasma.
AAHA advises thorough handwashing and cleaning and disinfection of bowls, utensils and preparation surfaces. Those reduce exposure; they do not prove zero risk.
Two processing myths worth retiring
- Freezing is not disinfection. WSAVA is explicit that freezing, drying or freeze-drying does not eliminate every pathogen.
- HPP is not sterility. High-pressure processing can reduce bacteria, but how much depends on the organism and the processing conditions. A label claim is not a guarantee that household transmission is impossible.
Our editorial guidance
If you feed raw in a household with a baby, an elderly relative, a pregnant person, or anyone immunosuppressed, that is the conversation to have with your veterinary team — including whether a cooked, nutritionally appropriate alternative would serve the same goals.
When to act
What the action labels mean
- Emergency now —
- contact an emergency veterinary service and arrange immediate assessment. Do not wait for the next scheduled feed or weigh-in.
- Call now for triage —
- telephone the veterinary service when you notice the sign. The veterinarian decides how quickly the animal needs to be seen.
- Contact today —
- get in touch when you notice the issue to agree on a time. This does not mean waiting until evening.
Emergency now
Choking or difficulty breathing, collapse, severe abdominal pain, or a swollen abdomen with unproductive retching. Gastrointestinal obstruction is an emergency — it can cause tissue damage, perforation and shock.
Call now for triage
Repeated vomiting, inability to keep water down, or suspected swallowed bone fragments. Persistent vomiting with pain or marked weakness becomes an emergency.
Contact today
New diarrhoea, a vomiting episode, or a change in behaviour or appetite after raw exposure in an otherwise alert, comfortable dog. Tell the clinic explicitly that raw, dried or freeze-dried products are involved, and keep the product identification and feeding history to hand.
Contact today
No symptoms, but a vulnerable household member. Book a feeding review. Raw exposure alone does not diagnose an infection.
Our editorial guidance
Do not plan to "watch for it to pass" after a swallowed bone. Whether to observe is a veterinary decision, sometimes involving serial imaging — not a default.
Two myths
- "My dog looks healthy, so nobody is being exposed." Symptom-free shedding is possible. A well-looking dog doesn't answer the infection question.
- "Frozen, freeze-dried or HPP means sterile." Covered above — these processes are not interchangeable and none is universal pathogen elimination.
Moving off raw, or onto it? Mix over days rather than overnight — changing food without overlooking illness.
