Raw or kibble? It is one of the most hotly debated questions in dog ownership, and the answer is rarely as clear-cut as either camp insists. This guide weighs up both honestly — the benefits, the genuine risks, the costs in 2026, and what the vets actually say — and because we put our own dog on a raw diet for a month, it is part guide and part real-world experience.

Raw vs kibble: what is the actual difference?

Kibble is dry, commercially processed food. The ingredients are ground, mixed, cooked at high temperature (a process called extrusion), then dried and sprayed with fats and flavourings. It is shelf-stable, convenient and, in any product labelled “complete”, nutritionally balanced by design.

Raw feeding (sometimes called BARF — biologically appropriate raw food) means uncooked meat, edible bone and offal, sometimes with vegetables and supplements. The idea is to feed something closer to what a dog would eat in the wild, with minimal processing. You can buy complete commercial raw (usually frozen), or prepare it yourself at home.

The case for raw feeding

Raw food is typically higher in protein and lower in the grain fillers found in cheaper kibble. Owners who switch frequently report the same handful of changes: firmer and smaller stools, fresher breath, a glossier coat, and fussy eaters suddenly clearing the bowl. There is some science pointing the same way — a few studies have found better digestibility markers and, in one 2024 trial, lower inflammation markers in raw-fed dogs — though most of this research is small-scale and the authors themselves call for longer studies. Treat the health claims as promising rather than proven.

The case for kibble

Kibble’s biggest strengths are convenience and consistency. A good “complete” kibble is formulated to meet a dog’s full nutritional needs in every bowl, with no planning required from you. It stores for months, travels easily, costs less, and takes the guesswork out of getting the balance right. Quality varies enormously, though: budget supermarket brands lean on fillers, meat derivatives and additives, while premium, cold-pressed or lightly baked foods retain more nutrients and use better ingredients. If you feed kibble, the brand matters far more than the format.

The honest risks — and what the vets say

This is where the raw debate gets serious, and where the original version of this article was a little too rose-tinted. Two real risks come with raw feeding:

Bacteria. Raw meat studies consistently find pathogens such as salmonella, E. coli, listeria and campylobacter — a risk not just to your dog but to everyone in the house, especially babies, elderly or immunocompromised people. Raw feeding demands proper hygiene: sealed storage, separate prep surfaces, thorough hand-washing and prompt clean-up.
Nutritional imbalance. Getting a raw diet right is harder than it looks. One 2022 analysis found that over 90% of homemade raw diets were nutritionally unbalanced. Commercially prepared “complete” raw is formulated to avoid this; DIY raw without expert input is where dogs come unstuck.

UK and international bodies land on the cautious side. The BVA does not ban raw feeding but advises owners to weigh the risks carefully and considers commercially prepared complete diets the safest option. The PDSA advises against home-preparing food — cooked or raw — without help from a pet nutrition specialist. The CDC and FDA advise against raw altogether on food-safety grounds. Holistic vets tend to be more supportive. In short: the profession is not unanimous, and neither side has a knockout scientific case.

Kibble is not risk-free either — heavy processing and poor-quality budget recipes are its weak points — but it is the easier diet to get right and the safer one for households with vulnerable people.

How much does each cost? (2026 UK)

Costs vary hugely with your dog’s size, the brand and whether you buy in bulk, so treat these as rough guides for a medium dog (around 15–20kg). We have led with the daily cost, as it is the fairest way to compare:

Budget kibble (Bakers, Pedigree): around 40–60p a day (~£15–25 a month) — heavy on fillers, not recommended
Mid-range kibble (Burns, Forthglade, Harringtons): around £1–1.50 a day (~£30–45 a month) — good quality and complete
Premium kibble (Orijen, Acana, Canagan): around £1.80–2.50 a day (~£55–75 a month) — high meat content
Budget / bulk raw (value mince boxes): around 85p–£1.20 a day (~£25–35 a month) — cheaper than most people expect
Mid-range commercial raw (Nutriment, Nature’s Menu): around £1.50–2.20 a day (~£45–65 a month) — complete and convenient
Premium commercial raw (Natural Instinct, Paleo Ridge): around £2.30–3.50 a day (~£70–110 a month)
Freeze-dried raw: the priciest, often £3 or more a day

For reference, Bentley’s complete raw from Nutriment came to about £1.50–1.80 a day — right in the mid-range commercial-raw band, and proof that raw need not be as eye-watering as it is often made out to be. Raw feeders also argue that better long-term health may mean fewer vet bills, though that is hard to prove and shouldn’t be assumed.

Our experience: Lord Bentley on raw

Lord Bentley trying Nutriment raw dog food — Lord Bentley taste-testing raw food from Nutriment

Our own dog, Lord Bentley — a working cocker spaniel, and a famously hyperactive one — had only ever eaten kibble (Skinners, Royal Canin, Eukanuba and Millies Wolfheart). We tried him on complete raw food from Nutriment for just over a month: a 500g tray a day, split across two meals, rotating chicken, turkey, and beef & tripe. There was no fuss — he wolfed it down from day one.

What we noticed:

Breath: still doggy, but noticeably less rancid.
Stools: firmer, smaller and far less smelly — reportedly because more of the food is absorbed and less goes to waste.
Behaviour: the biggest surprise — calmer and more responsive, with rather less of the selective hearing. (He still had his moments.)
Coat: seemed to flatten and darken a little, looking glossier — though some of that could be a seasonal change.

The catch was cost. Bentley needed a full tray a day, working out at roughly £1.50–£1.80 daily, against about 80p a day for the high-end Millies Wolfheart kibble — a noticeable difference over a year. He didn’t go back to the cheaper kibbles, but Millies remained an occasional alternative. Your mileage will vary: this is one dog’s experience, not a clinical trial.

How to switch from kibble to raw

If you decide to try raw, do it gradually rather than overnight. Speak to your vet first, especially if your dog has health issues. Start by mixing a little raw into the usual food and increase it over a week or two while you watch their stools, energy and skin. Choose a commercially prepared complete raw food rather than going DIY, unless you are working with a canine nutritionist, and keep hygiene tight throughout.

The verdict

Raw worked well for Bentley, and plenty of owners report the same. But it is not automatically “better” — it costs more than budget kibble, demands careful handling, and isn’t the right call for every dog or every household. Honestly, the raw-versus-kibble label matters less than two things: feeding a genuinely complete and balanced diet, and choosing quality over the cheapest option. Get those right, take your vet’s view into account, and either route can keep a dog thriving.

Frequently asked questions

Is raw dog food better than kibble?

Not automatically. Many owners report benefits like smaller stools and better coats, and some small studies are encouraging, but the evidence isn’t conclusive. A high-quality complete kibble can keep a dog just as healthy. What matters most is that the diet is complete and balanced.

Is raw feeding safe?

It can be, with care. The main risks are bacterial contamination and nutritional imbalance. Use a commercially prepared complete raw food, handle it hygienically, and take extra care in homes with babies, elderly or immunocompromised people. Speak to your vet before switching.

Is raw cheaper than kibble?

It can be closer than people think. Budget and bulk raw can rival mid-range kibble at around £1 a day, while premium commercial and freeze-dried raw cost more — especially for larger dogs. It is rarely cheaper than budget kibble, but it needn’t be the fortune it is often assumed to be.

Can I mix raw and kibble?

Many owners do, and it is a common way to transition. Some believe the two digest at different rates and prefer to feed them at separate meals; if in doubt, ask your vet.

Do vets recommend raw food?

Most mainstream UK vet bodies advise caution and favour commercially prepared complete diets as the safest option, while holistic vets are often more supportive. Opinion is genuinely divided.
