The Science Behind Raw Feeding: What Vets Do Not Always Tell You

The Science Behind Raw Feeding: What Vets Do Not Always Tell You

If you have been researching the best dog food for your pet, you have likely come across the concept of raw feeding. And you have probably encountered very different opinions about it. Your vet may have cautioned you against it. A neighbour at the dog park insists it changed their dog's life. Online forums go back and forth endlessly. It can be hard to know who to trust.


At PetCentral UAE, we think every pet owner deserves honest, evidence-based information rather than messaging shaped by commercial interest. So here is a straightforward look at what the science actually says about raw feeding, where the real risks lie, and what vets do not always have the time or the incentive to explain.

What is Raw Feeding?


Raw feeding is a way of nourishing your dog with whole, unprocessed food. That typically means raw meat, raw meaty bones, and organs, often alongside vegetables, eggs, and fruit. The most widely used model is called the BARF diet, which stands for Biologically Appropriate Raw Food. It was developed in the 1990s by Australian veterinarian Dr. Ian Billinghurst.


The thinking behind it is straightforward. Dogs evolved over thousands of years as carnivores. Their digestive systems developed for raw animal protein, not for highly processed commercial dog food cooked at extreme temperatures. A short, highly acidic digestive tract is not a coincidence. It is a biological feature shaped by millions of years of eating raw prey.

What the Science Actually Shows


Dogs Are Built for Raw Protein


A dog's stomach, when digesting protein, reaches a pH of around 1 to 2. That level of acidity is powerful enough to destroy most harmful bacteria. Their intestines are also much shorter than ours, which means food moves through quickly and leaves less time for bacterial growth. These features were not designed for kibble processed in industrial ovens. They were shaped by a diet of raw meat and bone.

Nutrient Quality in Raw Food vs Processed Dog Food


All commercial dry dog food is produced using high-heat extrusion, a process that shapes and cooks the mixture into pellets. That process is efficient, but it comes at a cost to nutritional quality. Research has shown the following:

  • Amino acids including taurine and lysine are reduced or damaged during high-temperature processing
  • Natural enzymes in raw food are destroyed above 47 degrees Celsius
  • B vitamins and vitamin C are significantly reduced through cooking
  • Omega-3 fatty acids lose potency when exposed to prolonged heat


Raw feeding preserves these nutrients in their original state. Many owners who switch their dogs to raw food report visible changes in coat condition, digestion, and energy levels. Those changes are consistent with improved nutrient absorption.

The Gut Microbiome Connection


Research into the canine gut microbiome is one of the most promising areas in pet nutrition science. A study published in Applied and Environmental Microbiology in 2017 found that dogs on raw meat-based diets had a measurably different gut microbiome compared to dogs eating kibble, with notably higher diversity.


Greater gut diversity is consistently linked to stronger immune function, better digestion, reduced inflammation, and improved overall health. This pattern mirrors findings in human nutrition, where ultra-processed diets are associated with a less diverse and less resilient gut environment.

Did You Know?


Dogs share approximately 99.6 percent of their mitochondrial DNA with wolves. While domestication has introduced certain adaptations over time, their core digestive physiology remains closely aligned with that of wild carnivores.

Why Vets Do Not Always Present the Full Picture


This is not a criticism of veterinarians. Most are dedicated professionals who genuinely care about animals. But there are real structural reasons why raw feeding does not always receive a fair hearing in a clinical setting.

  • Veterinary nutrition education is heavily sponsored by commercial pet food companies including Hill's, Royal Canin, and Purina. Many veterinary schools receive substantial funding from these brands, which shapes the curriculum.
  • Vets are trained to identify and manage risk. Bacterial contamination and nutritional imbalance are real concerns in raw feeding. But the risks associated with lifelong processed dog food consumption, such as obesity, dental disease, and chronic inflammation, receive far less attention.
  • There is limited large-scale peer-reviewed research on raw feeding, not because it is inherently dangerous, but because the commercial pet food industry funds the majority of research in this field and has little financial reason to investigate alternatives.
  • This does not mean your vet is wrong to raise questions. It means those questions deserve a fuller conversation than a simple warning against raw food.

Addressing the Real Concerns


Bacterial Contamination


The most frequently cited concern is bacteria. Salmonella and E. coli can be present in raw meat. That risk is worth taking seriously, especially in households with young children or immunocompromised adults. But there is important context that often gets left out.
    • Dogs' digestive systems are specifically adapted to handle the bacterial load present in raw meat. Their stomach acid and rapid gut transit time make them far more resilient than humans in this regard.
    • Studies confirm that raw-fed dogs excrete more Salmonella in their stools. However, there is no consistent evidence that raw-fed dogs themselves become ill at higher rates as a result.
    • The primary risk is cross-contamination to humans. Washing hands thoroughly, cleaning food preparation surfaces, and using dedicated bowls and utensils keeps that risk at a manageable level.

Nutritional Imbalance


A poorly planned raw diet can leave a dog deficient in key nutrients. This is a genuine concern, particularly for puppies and dogs with specific health conditions. The answer is not to avoid raw feeding but to approach it with a proper plan.

  • Follow the standard ratio of 80 percent muscle meat, 10 percent raw bone, and 10 percent organ meat, with at least half of the organ portion being liver
  • Rotate protein sources across chicken, lamb, beef, fish, and rabbit to ensure broad nutrient coverage
  • Add fish oil, kelp, and vegetables where needed to support micronutrient intake
  • Consult a veterinary nutritionist if your dog has a diagnosed health condition

PetCentral UAE Tip: If you are new to raw feeding, a pre-balanced commercial raw blend is a good way to start. It removes the guesswork while giving your dog all the benefits of whole, unprocessed dog food. We can recommend options suited to your dog's breed, size, and life stage.

What Owners of Raw-Fed Dogs Commonly Report


Beyond the research, a consistent pattern of observations emerges from owners across the UAE and globally who have switched to raw. These are not guaranteed outcomes, but they are widely reported:

  • Smaller, firmer stools with significantly less odour, which indicates better nutrient absorption
  • Cleaner teeth and fresher breath, as chewing raw meaty bones provides natural dental cleaning
  • A shinier, softer coat with less shedding
  • Improved energy and leaner body condition
  • Reduction in allergy symptoms such as chronic itching, recurring ear infections, and hot spots
  • More stable weight, particularly in breeds prone to becoming overweight on dry kibble

Is Raw Feeding Suitable for Every Dog?


Raw feeding is not the right approach for every animal in every situation. Some dogs require a different or modified diet:

  • Dogs with compromised immune systems, such as those undergoing chemotherapy or managing autoimmune conditions, may be at greater risk from raw bacteria and should be assessed individually
  • Puppies under eight weeks should not be on raw food and require either mother's milk or a carefully formulated puppy diet
  • Dogs with conditions such as pancreatitis or kidney disease may need a modified raw or gently cooked fresh food diet rather than standard raw feeding


If you are unsure, look for a vet who has genuine knowledge of and openness to raw feeding, rather than one who dismisses it without engaging with the evidence.

The Bottom Line


Raw feeding is grounded in a clear understanding of how dogs are built, how nutrients behave under heat, and how the gut microbiome influences overall health. It is not a fad. It is a return to a way of feeding that aligns with biology.


The science does not claim raw feeding is without risk. But it also does not support treating it as inherently dangerous for healthy dogs in well-managed homes. What it does support is asking better questions about the dog food we choose, and not simply defaulting to whatever the commercial industry promotes most loudly.


Your dog deserves food that works with their body, not against it. And at PetCentral UAE, helping you find that is exactly what we are here for.
