Best dog food UK — what to actually feed your dog

The four main food types

Dog food in the UK falls into four broad categories. Understanding what each one is. Before you read any brand claims. Is the starting point.

Dry kibble

The most widely fed food in the UK. Kibble is convenient, shelf-stable, and cost-effective. Quality ranges from very poor (high cereal content, vague meat derivatives) to excellent (high named-meat content, minimal fillers). It's the easiest starting point for most owners, but the gap between the worst and best kibble on UK shelves is enormous. A cheap supermarket kibble and a premium brand kibble are fundamentally different products despite both being called "dry dog food".

Wet food

Wet food. Pouches, trays, and tins. Contains around 70–85% moisture, which makes it closer to a dog's natural diet and better for hydration. It's typically more palatable, which makes it useful for fussy eaters, dogs recovering from illness, or senior dogs with reduced appetite. The trade-off is cost (wet food is significantly more expensive calorie-for-calorie than kibble) and that it spoils within hours of opening.

Raw feeding (BARF)

Raw feeding. Biologically Appropriate Raw Food. Involves feeding uncooked meat, bones, organs, and some vegetables. Proponents argue it's closest to what dogs evolved to eat. Critics note the bacterial contamination risk (Salmonella, Listeria) for both dogs and the humans handling the food, and the risk of nutritional imbalances if the diet isn't properly formulated. In the UK, raw food for pets is regulated under the same rules as pet food generally. If you go raw, use a complete commercial raw diet rather than DIY unless you have specialist knowledge.

Mixed feeding

Using dry and wet food together. Kibble as the base with wet food as a topper. Is increasingly recommended by UK vets and nutritionists as a pragmatic balance. It provides the convenience and dental benefits of kibble alongside the palatability and hydration advantages of wet food. Most complete kibbles and wet foods can be combined without issue.

How to read a UK dog food label

This is where most owners stop reading, and where manufacturers hide the most. Under UK pet food labelling rules (inherited from EU Directive 2009/767/EC and retained post-Brexit), manufacturers must list ingredients by category in descending order of weight. Here's what to look for:

Good signs

• Named meat as the first ingredient: "Chicken (30%)", "Fresh salmon", "Lamb". Specificity is a positive sign.
• Named meat meal: "Chicken meal" or "salmon meal" are concentrated meat sources. Not necessarily bad, but should come after fresh named meat.
• Vegetables and botanicals listed by name rather than "vegetable derivatives".
• Oils named by source: "Sunflower oil" or "salmon oil" rather than "oils and fats".
• Short, recognisable ingredient list. The fewer mystery ingredients, the better.

Warning signs

• "Meat and animal derivatives" as the first or main ingredient. This legally means it could be almost anything from any animal.
• Cereals or derivatives as the primary ingredient. Maize, wheat, or rice listed before any meat source means the food is more grain than protein.
• Artificial preservatives: BHA (E320), BHT (E321), ethoxyquin (E324). These are legal but associated with health concerns in some research.
• Artificial colours: They serve no purpose except to make the food look appealing to the owner. Dogs don't care what colour their food is.
• "Sugar" or "glucose syrup" in the ingredients. Unnecessary and contributes to dental disease and obesity.

The percentage trick: UK rules require the percentage to be listed only for ingredients specifically highlighted in the product name or marketing. If a food is called "Chicken and Vegetable", the percentage of chicken and vegetable must be listed. Other ingredients can be listed without percentages. This is why premium brands voluntarily list all percentages — it's a transparency signal.

Protein percentage guidelines by life stage

The UK government's scientific advisory body (FEDIAF. The European Pet Food Industry Federation, whose standards apply in the UK) sets minimum nutrient requirements. These are minimums, not targets:

• Puppies (growth): Minimum 22.5% crude protein on a dry matter basis. In practice, quality puppy foods provide 28–35%.
• Adult maintenance: Minimum 18% crude protein on a dry matter basis. Most decent adult foods sit at 25–30%.
• Senior dogs: Contrary to old advice, most healthy senior dogs do not need reduced protein. They may actually need more, as ageing dogs absorb protein less efficiently. Unless your vet has recommended reduced protein for a specific health condition (e.g., kidney disease), don't choose a food specifically for being lower protein.

How much to feed by dog weight

Feeding guides on packaging are starting points. Adjust for body condition. You should feel ribs without pressing hard, but not see them at rest.

• 5kg dog (e.g., Chihuahua, small Dachshund): approx. 80–110g dry kibble daily
• 10kg dog (e.g., Cocker Spaniel): approx. 170–220g daily
• 20kg dog (e.g., Border Collie, Springer): approx. 280–360g daily
• 30kg dog (e.g., Labrador, German Shepherd): approx. 380–480g daily
• 40kg dog (e.g., large Labrador, Rottweiler): approx. 470–580g daily

Neutered dogs generally need 10–20% less than intact dogs. Highly active dogs (working dogs, regular off-lead running) may need 20–30% more. These are guidelines for a typical complete dry food at around 350–380 kcal per 100g. If your food is more calorie-dense, adjust down accordingly.

Puppy vs adult vs senior nutrition: the key differences

Puppies

Puppies need more protein, fat, calcium, and phosphorus than adults to support rapid growth. They also need more frequent feeding. Three to four meals daily until six months, then twice daily. Calcium and phosphorus ratios matter particularly for large and giant breed puppies, where excess calcium contributes to developmental orthopaedic diseases. Large breed puppies should be fed a food specifically formulated for large breed growth, not a standard puppy food.

Adults

Adult dogs (typically 12 months for small breeds, 18–24 months for large/giant breeds) need a balanced maintenance diet. The transition from puppy food should be gradual. Over 7–10 days. To avoid digestive upset. Two meals daily is standard for adults; once daily is acceptable for some dogs but twice daily is generally better for digestion and satiety.

Seniors

Senior dog foods are largely a marketing category. Most healthy senior dogs do well on a good quality adult food. Where genuine adjustments may be warranted: lower calorie density if the dog is less active and gaining weight, added joint supplements (glucosamine, chondroitin) for dogs with early arthritis, and higher quality protein if the vet identifies muscle loss. Always consult your vet before switching a senior dog with health conditions.

UK-specific context: DEFRA standards and regulation

In the UK, pet food is regulated under the Animal Feed (England) Regulations 2010 (and equivalent legislation in Scotland, Wales, and Northern Ireland), DEFRA oversight, and the retained EU Pet Food Directive. The Pet Food Manufacturers' Association (PFMA) operates a voluntary code of practice that most major UK brands adhere to.

Post-Brexit, UK pet food standards largely mirror EU standards but are now maintained independently. One practical implication: EU brands sold in the UK must comply with UK labelling requirements, which can differ slightly from their home market presentation. The UK has not adopted US AAFCO (Association of American Feed Control Officials) standards, so US nutritional claims on imported food don't directly translate to UK regulatory equivalents.

Common myths worth dismissing

Myth: Grain-free is healthier

Grain-free dog food became a major trend after the early 2010s, driven by human "paleo" diet trends applied to pets. In reality, dogs are omnivores who have co-evolved with humans to digest carbohydrates efficiently. Unlike cats, which are obligate carnivores. Dogs with diagnosed grain allergies benefit from grain-free diets, but these dogs are a small minority. For most dogs, the grain-free premium buys nothing. The US FDA's ongoing investigation into a potential link between grain-free diets and dilated cardiomyopathy (DCM), particularly diets high in legumes (peas, lentils), gives further reason for caution.

Myth: Raw is always safer and more natural

The "natural" argument for raw feeding is compelling but incomplete. Wild canids do eat raw meat. They also have a much shorter life expectancy, die from parasitic infections, and don't live in homes with children and immunocompromised people. Raw meat carries genuine bacterial contamination risks. A properly formulated complete raw diet from a reputable UK manufacturer (frozen to kill parasites, tested for contamination) is a reasonable choice for a healthy dog in a household without high-risk members. DIY raw feeding without nutritional expertise frequently results in imbalanced diets.

Signs your dog's food isn't right for them

• Coat quality: A dull, dry, or excessively itchy coat can indicate essential fatty acid deficiency or food intolerance.
• Digestive issues: Loose stools, excessive wind, or inconsistent stool texture that persists after the transition period suggests the food doesn't suit your dog.
• Energy levels: Persistent lethargy in an otherwise healthy dog can sometimes be traced to poor nutritional density.
• Skin and ear issues: Recurrent skin irritation, ear infections, or paw licking are common signs of food intolerances. Often to chicken or beef in dogs already exposed to those proteins repeatedly.
• Weight changes: Unexplained weight gain or loss despite consistent portions warrants a food review and vet check.

If you suspect a food intolerance, the diagnostic tool is an elimination diet. Typically a hydrolysed protein or novel protein diet for 8–12 weeks, with no other food sources. This should be done under vet guidance, not through self-diagnosis.
