The Downside of Feeding Raw Dog Food
May 09, 2025 | By Ashleigh Tosh
Raw feeding has become increasingly popular amongst dog owners all over the UK with many believing it's a more natural and beneficial way to nourish the nation's beloved pooches.
The idea of feeding dogs a raw diet stems from the belief that it mirrors their wild ancestors - full of fresh meat, bones, and organs - so it's certainly easy to see why it has such an appeal for owners' conscious of the overall health and wellbeing of their dogs.
But, while some dogs may thrive on a raw diet, it is not risk free.
From bacteria and nutritional imbalances to concerns raised by vets, raw feeding isn't a one-size-fits-all solution.
Here we'll explore the most important things to consider before feeding your dog a raw diet, plus give you some tips on how to make raw work for you if you'd like to explore it further.

Why Do Dog Owners Feed a Raw Diet?
 Many dog owners are drawn to raw feeding because it feels more instinctive and closer to what dogs might eat in the wild. Diets like BARF (Biologically Appropriate Raw Food) and RMBDs (Raw Meat-Based Diets) are marketed as a return to "natural" nutrition.
Lots of people find that when they switch to a raw diet their dogs have:
- • Shinier coats
- • Better poos
- • Increased energy
- • Reduced allergies
There's also the appeal of avoiding heavily processed foods, additives, and fillers sometimes found in other commercial diets.
Plus, raw feeding gives owners full control over ingredients, which can be especially helpful for dogs with food sensitivities or intolerances.
However, research into the long-term effects of raw feeding is still fairly limited, and while raw diets can work well for some dogs, they need to be carefully balanced and managed to avoid unintentional health risks.
Is a Raw Dog Food Diet Really Better?
Raw feeding is incredibly popular and advocates of it are a passionate bunch, but is it really "better," or is it just different?
A 2019 paper in Veterinary Record found "no strong evidence that raw diets provide superior health outcomes" compared to other complete, cooked dog foods.
In fact, UK organisations like the Kennel Club, PDSA, and UK Pet Food recommend approaching raw feeding with care, especially when it's done at home without nutritional guidance.
It's important to note, though, that their concern isn't just the diet itself - it's how it's prepared, stored, and handled.
So, although it's entirely possible to feed a raw diet safely and effectively, it's a much more involved process than simply swapping kibble for meat...
Nutritional Deficiencies in Raw Dog Food
 One of the most common pitfalls of raw feeding is getting the balance of nutrients wrong. Dogs, like humans, need a wide variety of nutrients in just the right amounts to stay healthy. That includes proteins, fats, carbohydrates, vitamins, and minerals - all tailored to their size, breed, life stage, and activity level.
Sometimes, when raw diets are home-prepared without expert input, they may lack:
- • Adequate calcium and phosphorus balance
- • Essential fatty acids like omega-3
- • Key vitamins such as D, E, and B-complex
- • Trace minerals including zinc and iodine
In fact, a study published in Vet Record Open found that over 60% of homemade raw diets were nutritionally incomplete. Puppies and pregnant dogs are particularly vulnerable to deficiencies, as their nutritional needs are more specific. Over time, these imbalances may lead to growth issues, weakened bones, and long-term organ strain - even if outward signs take time to appear.
Bacteria in Raw Dog Food - Is It a Health Risk?
Raw meat in general can contain a variety of harmful bacteria - not only for your dog but for everyone in your household. This may include:
- • Salmonella
- • Listeria monocytogenes
- • Escherichia coli (E. coli)
- • Campylobacter
While some healthy adult dogs can tolerate these bacteria without any obvious symptoms, they may still shed them in their poo or saliva, putting other pets and people at risk.
This is especially concerning in homes with babies, elderly individuals, or those with weakened immune systems.
Cross-contamination in the kitchen is also a big concern.
According to the UK Food Standards Agency, raw pet food should be stored separately, prepped with different utensils, and handled carefully to prevent potential bacterial spread.
In a nutshell, if you're feeding raw, it's really important you follow strict hygiene practices to keep everyone - dogs and humans - safe.
Can Dogs Eat Bones Safely on a Raw Diet?
 Bones are typically a big part of raw feeding as they provide both nutritional and dental benefits for your dog. Yet feeding bones isn't completely risk-free either. Even raw bones have the potential to cause problems particularly if they're the wrong size or type, or if they're eaten too quickly.
Dog owners have reported:
- • Broken teeth
- • Intestinal blockages
- • Constipation
- • Internal injuries if the bone splinters
Cooked bones can be particularly dangerous and should never be fed, as they are more likely to splinter and cause harm. The PDSA and Kennel Club advise caution when feeding any kind of bone and recommend always supervising your dog if you choose to include them.
If you're considering adding bones to your dog's diet, it may be a good idea to consult your vet first. They can help assess and advise you on whether it's appropriate for your dog's age and breed.
What Do UK Vets Say About Raw Feeding?
It's fair to say the vet community in the UK has mixed views on raw feeding. Many vets recognise that a well-formulated raw diet - especially from a reputable brand - can work well for certain dogs.
But others also raise concerns about safety, hygiene, and the number of dogs being fed unbalanced homemade diets.
The British Veterinary Association (BVA) has highlighted raw feeding as an area of "growing concern," noting the increase in cases of bacterial infections, nutrient deficiencies, and complications caused by feeding bones. The Royal College of Veterinary Surgeons recommends that raw diets should only be followed under veterinary guidance, particularly in households with vulnerable individuals.
So what does this mean? Are they for it or against?
Well, what it boils down to is this, loads of vets aren't anti-raw - they're pro-safe feeding. If you're thinking about making the switch, speak to your vet or a qualified pet nutritionist to ensure you're covering all bases and guaranteeing your pup's diet is complete, balanced and suitable for their individual life stage and overall needs.
How To Feed Your Dog a Raw Diet Safely
if you've decided that raw feeding is the right choice for you and your dog, just how do you go about it safely and in a way that makes sure your dog gets everything they need?!
Well, the simplest, and widely considered the safest, choice is to use a commercial raw dog food brand.
Look for products from DEFRA-registered companies, as these are required to meet rigorous UK hygiene and safety standards. Lots of these brands offer complete and balanced raw meals, designed by canine nutritionists to meet your dog's dietary needs at every life stage too.
You'll find commercial raw food is usually frozen or freeze-dried, and tends to include a mix of meat, offal, bone, vegetables and natural supplements - taking the guesswork out of meal planning. It also significantly reduces the chance of contamination that can occur when preparing raw meals at home.
We have lots of raw dog foods listed on the Dog Food Directory, so be sure to check it out!
If, however, you'd prefer to go the DIY route, it's probably a good idea to chat to your vet or a canine nutritionist about getting the right balance of nutrients into your dog's meals.
Whether you choose to feed a commercial or homemade raw food diet, good hygiene is non-negotiable, so always remember to:
- • Wash your hands thoroughly before and after handling raw food
- • Use separate utensils and surfaces for pet food preparation
- • Store raw food at the correct temperature
- • Clean food bowls after every meal
- • Keep raw meat away from human food at all times
It's also a good idea to schedule regular vet check-ups and keep an eye on your dog's weight, coat condition, and energy levels. These are useful indicators of whether their diet is supporting their overall health and wellbeing.
In Conclusion - Should You Feed Your Dog a Raw Diet?
There can be no doubt, raw feeding can work wonderfully for some dogs and owners, but it's not the best fit for every household. It requires time, knowledge, and a commitment to safety.
So, if you're drawn to the benefits but unsure about the risks, there are alternatives worth exploring like high-quality, fresh diets.
In the end though, the best dog food is one that meets your dog's nutritional needs, supports their health, and fits into your lifestyle. Whether you choose raw or cooked, the key is to base your decision on what works for you and your dog, and to get guidance from trusted professionals along the way.

Frequently Asked Questions
Is raw dog food safe for my dog?
Raw food can be safe when carefully prepared and nutritionally balanced, but it also carries risks of bacteria and nutritional imbalances. Always consult your vet before making the switch.
Can I feed my puppy a raw diet safely?
It’s possible, but it’s particularly challenging. Puppies need very specific nutrition for healthy development, so any raw diet should be formulated by a veterinary nutritionist or come from a reputable brand designed for puppies.
Is homemade raw dog food better than commercial raw food?
Not necessarily. Homemade raw diets can be harder to balance correctly, and carry higher contamination risks. Commercial raw food from trusted, DEFRA-registered brands is generally safer and more convenient.
