Checked 19 September 2026. Every figure carries its source and date, and where two credible sources disagree, both are shown rather than averaged.

Key Takeaways

  • The UK pet food market is roughly £4.3 billion including wild bird and pigeon food, or £3.9 billion excluding them, a difference of about £400 million (UK Pet Food).
  • Value rose about 4% while volume fell roughly 1%, so growth is coming from price and mix rather than from more food being sold.
  • 62% of UK households owned a pet in 2026, with around 36.5 million non aquatic pets (UK Pet Food).
  • The dog count depends entirely on the source: 15.5 million on UK Pet Food’s 2026 estimate against 11.1 million on PDSA’s 2025 estimate, a gap of 4.4 million (PDSA).
  • Owners spent an average of £34 a month on food and treats, and only a quarter usually looked for the cheapest price (Mintel).
  • The obesity gap is a commercial signal. 77% of owners believed their pet was a healthy weight while vets estimated 50% of dogs were overweight (UK Pet Food).
  • The US market is far larger and measured differently: $158 billion of total pet industry spending in 2025, with pet food and treats projected at $69.7 billion for 2026 (APPA).
  • Almost every headline pet statistic hides a definition, which is why this article states one with every figure.

Quick Answer

The UK pet food market is worth roughly £3.9 billion excluding wild bird and pigeon food, or £4.3 billion including them, and it grew about 4% in value while volume fell around 1%. Roughly 62% of UK households own a pet. The dog population is either 15.5 million or 11.1 million depending on which credible source you use, and the gap is methodological rather than one of them being wrong. For brands, the commercially important finding is not the headline size. It is that the market is growing on price, premiumisation and product mix while the physical volume of food sold is flat to falling.

Table of Contents

Pet industry statistics are quoted constantly and defined rarely. The same article will use a market figure that includes wild bird food, a dog population from one organisation, a spending figure from another and a US total that measures something else entirely. This guide states the definition alongside every number, explains the population discrepancy properly, and then covers what the figures actually mean for a brand selling online.

How to Read Pet Industry Statistics

Three types of organisation publish pet data and they measure different things. Trade associations such as UK Pet Food collect market data from members, who represent about 90% of the UK market, and run their own population surveys. Veterinary charities such as PDSA survey owners about welfare and behaviour. Market researchers such as Mintel survey buyers and track products. None is authoritative for everything, and their figures are not interchangeable.

Four numbers, four different definitions £4.3bn UK pet food including wild bird and pigeon food £3.9bn UK pet food excluding wild bird and pigeon food $69.7bn US pet food and treats, 2026 projection $158bn Total US pet industry, including vets and services Comparing the first with the last is the most common mistake in pet market coverage. They are not measuring the same thing.
Four figures that get quoted as though they were comparable.

The most common error in pet market coverage is comparing a UK pet food figure with a US total pet industry figure, which includes veterinary care, services, supplies and live animals. They differ by an order of magnitude because they measure completely different things.

How Big Is the UK Pet Food Market?

UK Pet Food’s 2026 market data puts the total UK pet food market at approximately £4.3 billion when wild bird and pigeon food are included, and approximately £3.9 billion when indoor bird food is included but wild bird and pigeon food are excluded (UK Pet Food). The data is collected annually from members, covers different formats and species, and reports both value and volume.

Whether wild bird food counts as pet food is a genuine definitional question rather than a technicality. It is bought by households, sold in the same aisles and included in some market definitions, but nobody is feeding a pet with it. The £400 million difference is large enough that quoting the wrong one materially changes a market size claim, so say which you mean.

Why Value Is Rising While Volume Falls

On the definition excluding wild bird and pigeon food, UK pet food market value increased by about 4% while volume declined by approximately 1%.

Value and volume are moving apart Market value what the market is worth up 4% Market volume how much food is sold down 1% Growth is coming from price and mix, not from more food going out the door UK Pet Food 2026 data, excluding wild bird and pigeon food.
UK Pet Food 2026 data, excluding wild bird and pigeon food.

That divergence is the most commercially useful finding in the whole dataset. A market growing in value while shrinking slightly in volume is not selling more food. It is selling more expensive food, or smaller packs at higher prices, or a different mix of products. We would not attribute the entire 4% to premiumisation, because the freely available headline data does not separate pricing from mix, pack size and inflation. The direction is clear enough though: growth plans built on selling more tonnes look harder than plans built on selling better.

How Much Owners Spend

Mintel reported in February 2024 that UK pet owners spent an average of £34 a month on pet food and treats, about £408 a year at that rate, and that only one quarter of owners usually looked for the cheapest price (Mintel). For an online brand that second figure matters more than the first, because it suggests price is a qualifier rather than the deciding factor for most of the market.

Pet Ownership and Population

UK Pet Food estimated that 62% of UK households owned a pet in 2026, with approximately 36.5 million non aquatic pets (UK Pet Food). Dogs led at 41% of households and cats at 31%, followed by indoor birds at 2.7%, tortoises and turtles at 1.6%, snakes at 1.3%, guinea pigs at 1.2%, domestic fowl and rabbits at 1.1% each and horses or ponies at 1%. Separately, 13% of households had an indoor fish tank and 11% an outdoor pond.

The survey behind those numbers was conducted online by Kantar and Soulor Consulting in January 2026 with 8,951 respondents, with an estimated margin of error of plus or minus 1% at 95% confidence, and the published population estimates are rounded to the nearest 100,000.

Why UK Pet Population Figures Differ

This is where pet statistics get genuinely confusing, and where most articles simply pick whichever number suits them.

Two credible dog counts, 4.4 million apart UK Pet Food, 2026 PDSA, 2025 15.5 million dogs 13 million cats Share of households 8,951 respondents 11.1 million dogs 10.5 million cats Share of adults 10,975 asked first Different years, groups and methods. Pick one and say which. Neither is wrong. Blending them into one UK figure would be.
Both are credible. They are answering slightly different questions.

Five things explain the gap. The methods differ: UK Pet Food takes the percentage of respondents owning a species, applies it to ONS household data and multiplies by the average number of that species per relevant household (UK Pet Food), while PDSA starts with an incidence question asked to 10,975 UK adults, then surveys 5,387 dog, cat and rabbit owners drawn from a panel and weights the results (PDSA).

The base differs. UK Pet Food commonly reports ownership as a share of households, PDSA as a share of adults, and a household can contain several adults. The years differ, with UK Pet Food’s figures from January 2026 and PDSA’s fieldwork running from December 2024 into January 2025. UK Pet Food changed its method, moving from face to face to online research in 2021, and says online surveys tend to produce somewhat higher ownership estimates, which is why it advises against comparing figures across that change.

And UK Pet Food withheld a year. It chose not to publish its 2025 population data after the results suggested a higher than expected dog population, and identifies 2026 as its latest validated figures (UK Pet Food), which is a level of transparency worth acknowledging. So which is correct? Both, for what each measures. Pick one, say which, and use it consistently rather than blending them into a number neither organisation would recognise.

What Is Driving Market Value

Mintel describes premiumisation and humanisation as the two forces shaping the category (Mintel). Premiumisation shows up in the value and volume divergence and in the finding that only a quarter of owners hunt for the cheapest option. Humanisation shows up in recipes, positioning and packaging that resemble human food, and in the willingness to pay for formats that would have seemed eccentric a decade ago.

Health claims are now mainstream rather than a niche. Mintel reported that 60% of UK pet food buyers in 2023 said healthiness affected whether they bought a product, and that more than half of new pet food launches in its database that year carried health claims (Mintel). That makes substantiation a competitive issue as well as a regulatory one, which our pet food ecommerce guide covers in detail.

Category Trends

  • Fresh and chilled. Mintel found two fifths of UK pet food buyers interested in chilled pet food, with 14% willing to pay more, rising to almost a quarter of 16 to 35 year olds, though the market remains overwhelmingly ambient and long shelf life (Mintel).
  • Raw. UK Pet Food said in February 2026 that it represented 15 dedicated raw manufacturers, and stresses that microbiological risk must be managed through manufacturing controls and responsible handling (UK Pet Food).
  • Grain free, functional and fortified. Mintel identifies these among the main product development themes, alongside digestion and prebiotic claims.
  • Insect protein. UK Pet Food has published a scenario in which insect protein could reach 20,000 tonnes a year at 5% of the market, based on 2019 research. That is a potential figure rather than measured current sales, and should never be quoted as the latter.

One retailer signal is worth including with a caveat. Ocado reported combined unit sales across Lily’s Kitchen, Scrumbles, Forthglade, tails.com and Edgard and Cooper up 33.5% year on year in September 2025, with individual products rising far more (Ocado). Those are single retailer figures for particular products, not UK category growth rates, and they should never be presented as the latter.

Pet Health as a Commercial Signal

UK Pet Food’s 2024 obesity research found 77% of owners believed their pet was a healthy weight and only 4% said their pet needed to lose weight, while veterinary professionals estimated 50% of dogs, 43% of cats, 31% of small mammals and 9% of birds were overweight or obese (UK Pet Food). The survey covered 148 veterinary professionals at the London Vet Show in November 2023 and 2,558 households in March 2024.

The behavioural findings underneath are the commercially useful part. Only 25% of owners regularly weighed their pet, only 7% knew how to assess body condition correctly, half had never discussed weight with a vet, 63% said they followed feeding guidelines, 34% fed human food scraps and 18% did not weigh out food at all. That is a merchandising gap rather than a lecture: portion guidance, feeding calculators and clear daily quantities help owners who genuinely do not know, and they also drive pack size and subscription cadence, which our product page guide covers from the layout side.

How the UK Compares With the US

The American Pet Products Association reported total US pet industry expenditure of $158 billion in 2025, up 3.7%, projecting $165 billion for 2026, with 95 million US households owning at least one pet, 53% owning a dog and 39% a cat (APPA). For 2026 it projects $69.7 billion on pet food and treats, $42.4 billion on veterinary care and product sales, $35.6 billion on supplies, live animals and over the counter medicines, and $14.9 billion on other services (APPA).

The comparison to avoid is £3.9 billion against $158 billion. The UK figure is pet food. The US headline is the entire industry including vets, grooming, boarding and insurance. The closer comparison is UK pet food against the US pet food and treats projection, and even then the definitions, channels and data sources differ, since APPA uses NielsenIQ data supplemented with estimates for uncovered channels.

What the Numbers Mean for Pet Brands Online

  1. Pet food suits subscriptions structurally, because consumption is predictable and the reorder date is calculable from pack size and daily quantity (subscriptions guide).
  2. Cadence beats discounting for retention. A dog eating 400g a day gets through 12kg in 30 days, so the delivery interval should follow that rather than a default month.
  3. Pack size economics decide contribution, since heavy products punish low value orders, which our returns statistics and conversion rate guide both touch on from the margin side.
  4. Premium has to be defensible, because with only a quarter of owners chasing the lowest price, the question is what justifies your price rather than whether you can charge one.
  5. Health needs merchandising, not just claims. The obesity findings show owners want guidance and lack the knowledge to apply it.
  6. Growth is increasingly a share battle. With volume flat and value rising, someone else’s customer is the growth, which makes retention and inventory discipline central (inventory apps guide).

Methodology and Update Schedule

Checked 19 September 2026. Market and population data comes from UK Pet Food and PDSA, consumer research from Mintel, US data from APPA and retailer data from Ocado, each named where used. Market definitions are kept separate throughout, so pet food, pet food including wild bird food, US pet food and treats and total US pet industry spending are never blended. Population estimates are attributed to their source rather than averaged, and retailer figures are labelled as single retailer data rather than category growth.

On updates, population figures are reviewed annually when UK Pet Food and PDSA publish, market data annually, and event dates ahead of each season. This is a market statistics page. The operational and regulatory side, including UK feed law, APHA approval and US label changes, is covered in our pet food ecommerce guide.

Why Matters Perspective

The statistic most pet brands quote is the market size. The one that should change their plan is the value and volume divergence. A market growing 4% in value while shrinking 1% in volume is telling you that the extra money is coming from price, mix and premium formats, not from more animals or more food. That makes retention, pack architecture and justified premium the growth levers, rather than acquisition volume.

The second most useful finding is the obesity gap, because it is a rare case of research pointing directly at a merchandising fix. Owners are not refusing to feed correctly. Most do not know how, do not weigh their pet and have never discussed it with a vet. A feeding calculator that turns a pet profile into a daily quantity, a pack size and a delivery date answers a genuine problem and sells the right product at the same time.

Frequently Asked Questions

What is the UK pet food market size?

UK Pet Food's 2026 data puts the market at roughly £4.3 billion including wild bird and pigeon food, or about £3.9 billion excluding them. Always say which definition you are quoting, because the difference is around £400 million.

Is the UK pet food market growing?

In value, yes. On the definition excluding wild bird and pigeon food, value rose about 4% while volume fell roughly 1%, so the market is growing on price and product mix rather than on more food being sold.

How many dogs are there in the UK?

It depends on the source. UK Pet Food estimated around 15.5 million in 2026, while PDSA estimated 11.1 million in 2025, a gap of 4.4 million caused by different years, sampling and whether ownership is measured by household or by adult.

How many cats are there in the UK?

UK Pet Food estimated around 13 million in 2026 and PDSA estimated 10.5 million in 2025. As with dogs, the two are separate estimates rather than competing versions of one number.

How many UK households own a pet?

UK Pet Food estimated 62% of UK households owned a pet in 2026, with roughly 36.5 million non aquatic pets, including 41% of households owning a dog and 31% owning a cat.

Which pet population figure should a business use?

Pick one source, state it, and use it consistently. UK Pet Food suits household level market sizing, PDSA suits welfare and owner behaviour. Blending them produces a number neither organisation would recognise.

How much do UK owners spend on pet food?

Mintel reported an average of £34 a month on pet food and treats in February 2024, which is about £408 a year at that rate, and found only a quarter of owners usually looked for the cheapest price.

Why does pet obesity matter to pet food brands?

Because it creates a merchandising gap. UK Pet Food research found 77% of owners believed their pet was a healthy weight while vets estimated 50% of dogs and 43% of cats were overweight, and only 7% of owners knew how to assess body condition.

Final Thoughts

UK pet food statistics are better documented than most sectors and more frequently misquoted than almost any. The market is around £3.9 billion or £4.3 billion depending on definition, growing in value and flat to falling in volume. The dog population is 15.5 million or 11.1 million depending on the source, and understanding why is more useful than picking a side. Quote the definition with the number, keep the sources separate, and use the value and volume divergence to decide where your growth is actually going to come from.
