Raw Dog Food: Is It Safe? What Vets Really Think

Reviewed by Dr. Jamshed Bilal, DVM

Raw feeding has gone mainstream. It is no longer a niche practice among enthusiasts — it is a significant and growing segment of the pet food market, with commercial raw products available in most major pet stores and a passionate community of advocates online. But is it actually better for your dog, or is the science more complicated than the trend suggests? Here is an honest look at what the evidence shows, what the risks are, and what vets genuinely recommend.

What Is a Raw Dog Food Diet?

A raw dog food diet — most commonly referred to as a BARF diet (Biologically Appropriate Raw Food, or Bones And Raw Food, depending on who you ask) — is a feeding philosophy based on the idea that dogs should eat what their ancestors ate: raw, unprocessed animal ingredients. The framework was popularised by Australian veterinarian Ian Billinghurst in his 1993 book "Give Your Dog a Bone," and has grown substantially since.

In practice, a BARF-style diet typically includes raw muscle meat, raw meaty bones, raw offal (particularly liver and kidney), and in many formulations, raw vegetables, fruit, eggs, and dairy. The proportions typically follow a loose guideline of approximately 70% muscle meat, 10% raw meaty bones, 10% offal, and 10% other items, though this varies significantly between advocates and practitioners.

Commercial raw food is a second category — industrially produced products that use raw meat ingredients, typically ground or minced, and sold fresh, frozen, or freeze-dried. These products are subject to manufacturer quality controls and some level of contamination testing, though standards vary. Freeze-dried raw is a higher-convenience format where raw ingredients are freeze-dried to remove moisture while preserving nutrients, making them shelf-stable; they are rehydrated before feeding and generally carry lower — though not zero — bacterial risk than fresh raw.

Homemade raw is the third category — food prepared by the owner from raw ingredients sourced from butchers, supermarkets, or specialist suppliers. This carries the highest nutritional and contamination risk of the three, because the owner is solely responsible for both nutritional completeness and food safety.

Why Are So Many Owners Switching to Raw?

The appeal of raw feeding is understandable and not irrational. Owners report dramatic improvements in their dogs — shinier, fuller coats; significantly smaller and less odorous stools; improved muscle condition and healthy weight maintenance; reduced flatulence; and in some cases, resolution of chronic skin conditions that had not responded to other interventions. These owner-reported benefits are too widespread and consistent to dismiss entirely, and they point to genuine biological responses — improved digestibility and a macronutrient profile closer to what a carnivore's digestive system is optimised for.

There is also an understandable scepticism toward the industrial pet food industry among some owners — a sense that highly processed, heavily marketed commercial food is not the best that can be offered to a beloved pet. This intuition, while not straightforwardly borne out by the evidence, reflects genuine concerns about industry practices and ingredient quality in lower-tier commercial products.

What Does the Science Say?

Honestly, the scientific evidence base for raw dog food is limited and mixed. There are very few well-designed randomised controlled trials comparing raw diets to commercial diets in dogs. The existing research includes some genuinely interesting findings alongside significant caveats.

A small number of studies have found that dogs fed raw diets show differences in gut microbiome composition compared to kibble-fed dogs, with some markers suggesting improved microbiome diversity. Other studies have found higher apparent digestibility of some nutrients in raw-fed dogs. Stool volume reduction in raw-fed dogs is a consistent and well-documented finding, reflecting the higher digestibility of a meat-dominated diet compared to a carbohydrate-rich kibble.

However, the same studies frequently highlight contamination risks, and the larger picture from veterinary medicine is one of limited evidence for the claimed health benefits and well-documented evidence for the risks. The WSAVA (World Small Animal Veterinary Association) position statement on raw feeding notes that the scientific evidence does not support the claimed benefits of raw diets and explicitly highlights the bacterial contamination risk. This does not mean raw food is definitively harmful to healthy adult dogs in otherwise low-risk households — it means the evidence for superiority over quality commercial food is not established.

The Real Risks of Raw Dog Food

Bacterial contamination for dogs and humans. This is the primary, most significant risk and the one that most influences the mainstream veterinary position. Raw meat routinely carries Salmonella, Listeria monocytogenes, E. coli, Campylobacter, and other pathogens. Multiple studies have detected these pathogens in commercially produced raw pet foods at rates significantly higher than in commercial cooked pet food. Importantly, a dog can carry and shed these pathogens in their faeces and saliva without showing any signs of illness — meaning owners can be exposed through normal handling, contact with surfaces, and contact with the dog itself. The CDC has documented Salmonella outbreaks in humans that have been traced to handling raw pet food. For households with infants, elderly people, pregnant women, or immunocompromised individuals, this risk is amplified significantly.

Bone splinter danger. Raw meaty bones are a common component of BARF diets and have a better safety profile than cooked bones — cooked bones are brittle and splinter unpredictably, while raw bones are more flexible. However, raw bones are not without risk. Large weight-bearing bones (like marrow bones from large animals) can fracture teeth. Smaller bones fed whole can, in some cases, cause choking, obstruction, or gastrointestinal perforation. These risks are not universal — many dogs eat raw bones without incident for years — but they are real and should be understood before implementing this part of a raw diet.

Nutritional imbalance in homemade diets. Creating a nutritionally complete homemade raw diet is genuinely difficult. Without formulation by a board-certified veterinary nutritionist, homemade raw diets commonly fail to meet requirements for calcium and phosphorus (inadequate bone or improper ratio leading to metabolic bone disease), vitamin E (oxidises rapidly in raw fat), iodine, zinc, and essential fatty acid ratios. These deficiencies may not be apparent for months or even years but can produce serious and sometimes irreversible health consequences, particularly in growing puppies, pregnant or lactating females, and senior dogs.

Not suitable for all dogs. Dogs with compromised immune systems, those undergoing chemotherapy or on immunosuppressant medications, those with acute gastrointestinal disease, puppies under 12 weeks, and senior dogs with reduced immune function are at higher risk from raw feeding. Households where raw food will be handled near vulnerable humans should take this risk very seriously.

If You Do Feed Raw — How to Do It Safely

For owners who have considered the evidence, accept the risks, and have a household without vulnerable individuals, commercial raw from a reputable supplier is the safest approach. Look for commercial raw products that are human-grade sourced, batch-tested for pathogens, nutritionally complete and balanced to AAFCO or FEDIAF standards, and produced under HACCP (Hazard Analysis and Critical Control Points) food safety frameworks.

Hygiene protocols are non-negotiable: separate raw food preparation surfaces from human food; use dedicated stainless steel or ceramic bowls (not porous plastic) that are washed in hot water with detergent after every meal; thaw raw food in the refrigerator, not at room temperature; wash hands thoroughly before and after handling raw food and after contact with the dog during and after feeding; do not allow the dog to lick faces or hands immediately after eating.

Regular veterinary health monitoring — including faecal screening for pathogens — is good practice for raw-fed dogs. Report any gastrointestinal signs promptly. Annual comprehensive blood panels catch nutritional deficiencies that may develop slowly.

What Vets Actually Recommend

Mainstream veterinary organisations consistently recommend against raw feeding, primarily on the grounds of the bacterial contamination risk to humans and dogs, the lack of evidence for claimed health benefits over quality commercial food, and the risk of nutritional imbalance particularly in homemade preparations. The WSAVA guidelines, American Veterinary Medical Association (AVMA) policy, and BSAVA (British Small Animal Veterinary Association) position all reflect this stance.

Some integrative and holistic vets take a more permissive view, supporting commercial raw feeding with appropriate safety precautions for healthy adult dogs in low-risk households. This reflects a genuine clinical difference of opinion rather than one side being simply uninformed. The honest summary is that mainstream veterinary consensus is against raw feeding, with some qualified dissent from integrative practitioners who work with raw-fed patients and report positive outcomes in appropriate cases.

Commercial Raw vs Homemade Raw

If you choose raw feeding, commercial raw is substantially safer than homemade raw on both nutritional and contamination grounds. Reputable commercial raw manufacturers employ veterinary nutritionists to formulate balanced products, source ingredients to defined standards, and conduct batch contamination testing. None of this is possible in a home kitchen. The WSAVA is explicit that homemade raw diets are not recommended without formulation by a board-certified veterinary nutritionist. For owners who want the benefits associated with raw feeding without the highest-risk aspects of homemade preparation, high-quality commercial raw — or freeze-dried raw as an even more convenient and lower-contamination option — represents a middle ground that some vets support.

Frequently Asked Questions

Is raw dog food better than kibble?

The evidence does not establish clear superiority of raw over high-quality commercial kibble. Some real benefits are reported and plausible, but the risks — particularly bacterial contamination and nutritional imbalance in homemade preparations — are well documented. High-quality commercial wet or dry food fully meets dogs' nutritional needs without these risks.

Can raw dog food make humans sick?

Yes. Dogs fed raw food shed pathogens in faeces and saliva, contaminating household environments. Multiple human Salmonella outbreaks have been linked to raw pet food handling. The risk is particularly serious for vulnerable household members.

What is the safest way to feed raw?

Use commercially produced, batch-tested raw food; follow strict hygiene protocols; avoid raw feeding in households with vulnerable individuals; maintain regular veterinary monitoring. Never use homemade raw without veterinary nutritionist oversight.

Can puppies eat raw food?

Not recommended under 12 weeks, and only commercially prepared and balanced raw food for older puppies. Homemade raw during the growth phase carries a serious risk of nutritional imbalance causing developmental bone disease.

What do most vets recommend for dog food?

Complete and balanced commercial food — wet or dry — meeting AAFCO or FEDIAF standards from a reputable manufacturer with qualified nutritionists and quality control testing. This is the mainstream veterinary consensus.
