Dog Food UK: The Complete Feeding Guide

Choosing what to feed your dog is one of the most consequential decisions you make as an owner. The UK pet food market is large, noisy and full of marketing claims that outpace the evidence behind them. This guide cuts through it: covering the types of food available, how to read a label, how to feed by life stage, what the evidence says about raw feeding, and which supplements are worth considering.

Types of Dog Food Available in the UK

Complete dry kibble The most widely fed format in the UK. Convenient, relatively affordable, shelf-stable and available in a wide range of formulations. "Complete" means it meets all nutritional requirements as the sole diet. Quality varies enormously: the ingredient list and nutritional analysis matter more than the packaging.

Wet food (canned or pouched) Higher moisture content (typically 75 to 85%), more palatable for many dogs and useful for dogs with dental issues or kidney conditions that benefit from increased water intake. More expensive per calorie than dry food. Can be fed as the sole diet if complete, or mixed with kibble.

Cold-pressed food A relatively recent format: dry food produced at low temperature, which preserves more of the original nutrient profile than conventional high-temperature extrusion. Lower in starch than standard kibble. Typically fed at a lower volume than conventional dry food. Increasingly available in the UK from specialist manufacturers.

Raw feeding (BARF: Biologically Appropriate Raw Food) Raw meat, bone and offal, typically frozen or fresh. A significant minority of UK dog owners feed raw. The approach can provide a species-appropriate diet but requires care: nutritional balance is not automatic, and food hygiene risks (Salmonella, Campylobacter) are real. Covered in more detail in our Raw Feeding Guide.

Fresh subscription food Cooked, human-grade fresh food delivered in portioned pouches. The fastest-growing segment of the UK pet food market. More expensive than kibble but highly palatable and easy to portion. Quality and nutritional completeness vary by provider: check for FEDIAF-compliant nutritional standards.

How to Read a Dog Food Label

In the UK, dog food labelling is governed by EU-derived regulations that remained in force after Brexit. Post-Brexit, the relevant standard is maintained by the Pet Food Manufacturers' Association (PFMA) in alignment with FEDIAF (the European Pet Food Industry Federation) guidelines.

Key things to check on the label:

"Complete" vs "Complementary" A complete food provides all nutrients required as the sole diet. A complementary food (mixer, topper, treat) does not and must be fed alongside a complete food. Never feed a complementary food as the main diet.

Ingredients list Listed by weight before processing, in descending order. Named meat sources (chicken, salmon, lamb) are more informative than generic terms (meat and animal derivatives, poultry). The proportion of named meat matters: a product with chicken as the first ingredient may still contain more grain than meat overall if multiple grain ingredients follow.

Analytical constituents The guaranteed analysis: protein, fat, fibre and moisture percentages. These allow comparison between products on a dry-matter basis. A high moisture wet food with 8% protein looks lower than a dry food with 28% protein, but on a dry-matter basis the two may be similar.

Additives Includes vitamins, minerals, preservatives and colourants. Artificial colourants serve no nutritional purpose and are worth avoiding. Preservatives are necessary for shelf stability: natural preservatives (vitamin E, rosemary extract) are preferable to BHA, BHT and ethoxyquin.

Feeding by Life Stage

Dog food should be matched to life stage. Feeding a puppy food formulated for adults risks nutritional deficiency; feeding an adult food to a growing large-breed puppy can drive excess growth and joint problems.

Puppies: require more protein, fat and calcium relative to body weight than adults. Large-breed puppy foods have controlled calcium and phosphorus ratios to prevent too-rapid growth. Feed a puppy-specific complete food until the breed's adult size is reached (6 to 24 months depending on size).

Adults (1 to 7 years, breed-dependent): maintain on a complete adult food. Adjust quantity for body condition: ribs should be felt but not seen, a waist visible from above.

Senior dogs: nutritional needs shift. Many seniors need fewer calories but maintained protein levels, increased omega-3 for joint support, and potentially adjusted phosphorus levels if kidney function is declining. Senior-specific complete foods address most of this; prescription diets are available for dogs with specific conditions.

Pregnant and lactating bitches: significantly increased energy and nutritional requirements. A high-quality puppy food or a food specifically formulated for breeding females is typically recommended. Discuss with your vet.

Breed-Specific Nutritional Considerations

Large and giant breeds: at risk of musculoskeletal problems if calcium and calorie intake drives too-rapid growth during puppyhood. Large-breed puppy formulas address this.

Brachycephalic breeds (French Bulldogs, Pugs, Bulldogs): jaw shape may make certain kibble sizes and shapes difficult. Wet food or small-kibble dry food often works better.

Deep-chested breeds (Great Danes, Weimaraners, Dobermanns): elevated risk of bloat (GDV). Feed smaller meals, use a slow-feeder bowl, and avoid exercise immediately before or after feeding.

Working and highly active breeds: significantly higher calorie requirements than sedentary dogs of the same size. A performance or working dog formula may be appropriate during high-activity periods.

Dogs prone to weight gain (Labradors, Beagles, Cavalier King Charles Spaniels): strict portion control and body condition monitoring is essential. The PFMA dog size guide provides weight ranges to cross-reference.

Foods Dogs Cannot Eat

A number of common foods are toxic to dogs:

Emergency level (veterinary attention required):

• Grapes and raisins (even small amounts can cause kidney failure)
• Xylitol (artificial sweetener in some peanut butters, chewing gum and baked goods: causes rapid blood sugar drop and liver failure)
• Chocolate (theobromine toxicity: dark chocolate is most dangerous)
• Onions and garlic (all forms: raw, cooked, powder)
• Macadamia nuts

Significant risk:

• Cooked bones (splinter and cause internal injury: raw bones are a separate consideration)
• Alcohol
• Caffeine
• Avocado (persin in the flesh and pit)
• Nutmeg

If you suspect your dog has ingested a toxic food, call your vet or the Animal Poison Line (0300 999 0077) immediately. Do not wait for symptoms. See our full guide to Foods Dogs Cannot Eat for comprehensive detail.

Raw Feeding: What UK Owners Need to Know

Raw feeding has a significant following in the UK. The PFMA estimates that around 10 to 15% of UK dog owners feed some raw food. The evidence on health outcomes is mixed: there are no large-scale controlled studies demonstrating superiority over commercial complete diets, but many owners report positive results in coat condition, digestive health and energy levels.

The key considerations for UK owners:

Nutritional balance: a raw diet based on muscle meat alone is not nutritionally complete. The standard framework (80% muscle meat, 10% raw bone, 10% organ, with at least half the organ being liver) provides a starting structure, but nutritional analysis by a qualified nutritionist is the gold standard.

Food safety: raw meat contains pathogens including Salmonella, Campylobacter and Listeria. The BVA advises caution regarding raw feeding, particularly in households with immunocompromised people or young children. Strict hygiene protocols are essential: separate surfaces, dedicated utensils, thorough handwashing.

Not suitable for: immunocompromised dogs (on chemotherapy or immunosuppressants), or households with immunocompromised people.

Supplements: What Actually Works

The UK supplement market is large and under-regulated. Claims on packaging are not subject to the same evidential standard as pharmaceutical drugs. The following have the most evidence:

Omega-3 fatty acids (EPA and DHA from fish oil): the strongest evidence base of any canine supplement. Reduces joint inflammation, supports cardiovascular health and coat condition. Dose by body weight: discuss with your vet.

Glucosamine and chondroitin: widely used for joint support. Evidence is moderate: some dogs respond well, others less so. Worth trying in conjunction with veterinary advice for dogs with arthritis.

Probiotics: some evidence for supporting gut health after antibiotic treatment or in dogs with chronic digestive issues. Use a dog-specific probiotic rather than human products.

Avoid: supplements making extravagant claims without evidence, products not specifically formulated for dogs, and supplements that duplicate nutrients already present in a complete food at appropriate levels.

Frequently Asked Questions

How much should I feed my dog?

Use the feeding guide on the packaging as a starting point, then adjust based on body condition. Ribs should be felt but not visible; a waist should be visible from above. Monitor weight at monthly vet weigh-ins and adjust portions accordingly. Body condition is a more reliable guide than the scales alone.

Is grain-free dog food better?

No evidence supports this for most dogs. Grain-free diets have been associated in ongoing FDA research with an increased risk of dilated cardiomyopathy (DCM) in some breeds. The research is not yet conclusive but the precautionary position is to avoid grain-free unless there is a specific veterinary reason to use it.

How do I transition my dog to a new food?

Over 7 to 10 days: 75% old food, 25% new food for days 1 to 3; 50/50 for days 4 to 6; 25% old, 75% new for days 7 to 9; 100% new from day 10. For sensitive stomachs, extend to 14 days.

Should I feed wet or dry food?

Both can be appropriate as the sole diet if they are complete. Wet food is better for hydration and palatability; dry food is better for dental health and cost per calorie. Many owners feed a combination. What matters most is that the food is complete, appropriate for life stage and the dog maintains a healthy body condition.

Are home-cooked diets safe for dogs?

They can be if properly formulated by a qualified veterinary nutritionist, but home-cooked diets are very difficult to balance correctly without expert input. Nutritional deficiencies in home-cooked diets are common and can cause serious long-term harm. Consult a registered veterinary nutritionist before switching to a home-cooked diet.

What is the PFMA?

The Pet Food Manufacturers' Association is the UK trade body for the pet food industry. It promotes standards for pet food safety and nutrition, aligned with FEDIAF guidelines. Their website (pfma.org.uk) has useful consumer guidance on feeding and labelling.
