Dog Food Cost Per Day UK
What UK welfare charities and consumer-finance sources actually report dog food costing, cross-checked against real per-day prices for named brands.
Quick answer
- ✓Budget on £0.45–£0.85/day for budget dry, £1.10–£1.40/day for mid-range or personalised dry, or £1.80–£4.00+/day for premium wet, prescription or fresh food.
- ✓These ranges are corroborated across three independent UK sources: Battersea, RSPCA, and MoneyHelper — not a single estimate.
- ✓Cost scales with your dog's size far more than with cats — a large dog can easily eat 2–3× what a small dog eats.
- ✓Food is typically the largest single monthly cost of dog ownership, per PDSA and RSPCA's total cost-of-ownership figures.
How much does dog food cost per day in the UK?
We cross-checked three independent UK sources — two welfare charities and one consumer-finance guide — rather than relying on a single estimate.
| Tier | Per day | Per month | What this looks like | Sources |
|---|---|---|---|---|
| Budget dry | £0.45–£0.85 | £14–£26 | Supermarket and mainstream dry (e.g. Harringtons, Wainwright's, James Wellbeloved) | Battersea: £10–£50/month; MoneyHelper: ~£25/month average |
| Mid-range dry / personalised | £1.10–£1.40 | £33–£42 | Personalised dry (e.g. tails.com) or breed-specific dry (e.g. Royal Canin, Millies Wolfheart) | RSPCA: £20–£80/month for a medium dog |
| Premium wet / prescription | £1.80–£2.80 | £54–£84 | Prescription dry (e.g. Hills Science Diet) or premium wet tins (e.g. Lily's Kitchen) | RSPCA: up to £205+/month for specialist food and larger dogs |
| Fresh / air-dried | £3.20–£4.00 | £96–£120 | Fresh cooked subscription (e.g. Butternut Box) or air-dried (e.g. Pure Pet Food) | Sits above general welfare-charity ranges — those estimates are typically based on standard kibble/wet, not premium fresh subscriptions |
Cost by named brand, per day
These per-day prices come from our own dog food comparison, based on current UK retail listings for a medium-sized dog (roughly 20–25kg). We multiplied by 30 for a monthly estimate.
| Brand | Price per day | Est. per month (×30) |
|---|---|---|
| Harringtons (dry) | ~£0.45 | ~£14 |
| Wainwright's (dry/wet) | ~£0.65 | ~£20 |
| Burns (dry) | ~£0.70 | ~£21 |
| Arden Grange (dry) | ~£0.75 | ~£23 |
| James Wellbeloved (dry) | ~£0.85 | ~£26 |
| tails.com (personalised dry) | ~£1.10 | ~£33 |
| Royal Canin (breed-specific dry) | ~£1.20 | ~£36 |
| Millies Wolfheart (premium dry) | ~£1.40 | ~£42 |
| Hills Science Diet (prescription) | ~£1.80 | ~£54 |
| Lily's Kitchen (wet) | ~£2.80 | ~£84 |
| Pure Pet Food (air-dried) | ~£3.20 | ~£96 |
| Butternut Box (fresh cooked) | ~£4.00 | ~£120 |
Fresh and air-dried subscriptions sit noticeably above the welfare-charity ranges quoted above — that's because those charity estimates are generally built around standard kibble and wet food, not the newer premium fresh-food category, which typically costs several times more per day.
What actually moves the cost
Your dog's size
This is the single biggest factor for dogs, far more than for cats. A Chihuahua eating 100–150g of dry food a day costs a fraction of what a Great Dane eating 700g+ a day costs, even on the exact same food. Always check the feeding guide for your dog's actual weight rather than assuming a flat daily cost.
Food type
Dry food is almost always the cheapest per day, ahead of wet, ahead of fresh/air-dried. The gap can be 5–10x between the cheapest dry and the most premium fresh subscription.
Prescription and veterinary diets
If your dog needs a prescription diet (kidney, urinary, weight management, allergy), expect to pay more than the standard premium tier — check with your vet's practice for current pricing.
Food cost vs the total cost of owning a dog
Food is usually the single largest recurring cost, but it's not the only one. Here's how it compares to the total monthly cost of ownership, per PDSA (2024) and RSPCA:
| Item | Monthly | Source |
|---|---|---|
| Food | £14–£120 | See tiers above; varies hugely by size and food type |
| Total cost (small dog) | ~£62–£69 | RSPCA: from £62; PDSA (2024): £69 |
| Total cost (medium dog) | ~£83 | PDSA (2024) |
| Total cost (large dog) | ~£100–£116 | RSPCA: over £100; PDSA (2024): £116 |
Battersea separately estimates the typical annual cost of owning a dog at around £1,800–£2,000, once food, insurance, healthcare and other essentials are combined.
Methodology: how we worked this out
We checked three independent UK sources — Battersea, RSPCA, and MoneyHelper — for their published food-cost estimates on 23 September 2026, then cross-referenced those ranges against the current per-day prices for twelve named brands in our own dog food comparison. We did not run our own household spending survey; every figure here is attributed to its original source, and you can follow the links below to check them yourself.
Limitations: this is a sourced specification-style comparison of published figures, not a hands-on audit of any specific dog's actual spending. Your dog's real cost depends heavily on their size, breed, appetite and any medical needs — use these ranges for planning, not as a guarantee.

❓ Frequently Asked Questions
How much does dog food cost per day?
Based on our price check of named UK brands, budget dry food runs about £0.45–£0.85/day, mid-range and personalised dry about £1.10–£1.40/day, premium wet or prescription food about £1.80–£2.80/day, and fresh or air-dried subscriptions about £3.20–£4.00/day. These are for a medium-sized dog roughly 20–25kg — a smaller dog eats less and costs less, a larger dog eats more and costs more, roughly in proportion to body weight.
Is 2 meals a day enough for a dog?
For most healthy adult dogs, yes — two meals a day (roughly 12 hours apart) is a common and sensible feeding pattern that also helps reduce the risk of bloat compared with one large meal. Puppies typically need 3–4 smaller meals a day due to their higher energy needs and smaller stomachs, tapering down as they mature. Always follow your specific food's feeding guide and your vet's advice for your dog's age, size and health.
What is the 80/20 rule for dog food?
This term is used in two different ways, so check which one a source means. Some use it to describe ingredient composition — roughly 80% meat or fish to 20% fruit, vegetables and other ingredients. Others use it for the overall diet — 80% of calories from complete, balanced dog food and up to 20% from treats and extras (some vets recommend an even stricter 10% limit for treats). There's no single official definition, so treat both versions as general guidance rather than a strict rule.
What is the average monthly cost of owning a dog in the UK?
PDSA's 2024 figures put the minimum monthly cost at roughly £69 for a small dog, £83 for a medium dog, and £116 for a large dog, covering food, insurance, flea/worm treatment and routine care. RSPCA's estimates are broadly similar — from about £62/month for a small dog to over £100/month for a large one, rising to £205+/month if you feed specialist food or buy premium extras. Food is typically the largest single line item within that total.
