Pet Ownership Statistics 2026: Every Number You Need

Key Statistics at a Glance

How Many Pets Are in the United States?

More than 200 million pets live in American homes as of 2024, according to the American Pet Products Association. Two-thirds of US households — roughly 87 million homes — own at least one pet. That number has held steady near 67% since the early 2020s, following decades of gradual growth.

The pet population spans dogs, cats, fish, birds, reptiles, and small mammals. Dogs dominate by household count, but freshwater fish far outnumber every other species in raw population. The distinction matters: "most popular" means different things depending on whether you count homes or animals.

These figures come from APPA's 2023–2024 National Pet Owners Survey, the industry's most cited data source. The survey samples over 16,000 households and is conducted every two years.

Multi-pet households are increasingly common. About 55% of pet-owning homes have more than one animal, per APPA's 2024 data. Roughly 38% keep two or more species under one roof — dogs and cats being the most common combination.

Dogs

Dogs are America's most popular pet by household count — 65 million households own at least one (2024). The total US dog population sits at roughly 90 million, according to APPA's 2023–2024 National Pet Owners Survey. That works out to an average of 1.5 dogs per dog-owning household.

Dog ownership has climbed 21% since 2000 when measured by the share of households with dogs, according to APPA historical survey data. Mixed breeds now account for over half of all owned dogs. The shift comes from the adoption movement and the popularity of designer crossbreeds like Goldendoodles and Labradoodles.

The American Kennel Club's 2024 registration data shows French Bulldogs holding the top spot for the third consecutive year. Labrador Retrievers, Golden Retrievers, German Shepherds, and Poodles round out the top five. Registration numbers reflect purebred purchases and do not capture the broader ownership landscape where mixed breeds dominate.

Dog size preferences have shifted toward smaller breeds over the past two decades. The average weight of newly acquired dogs has dropped from about 50 pounds in 2000 to roughly 40 pounds in 2024. Apartment living, urban migration, and aging demographics all favor smaller animals. For a full breakdown of breed popularity, ownership demographics, and spending per dog, see our dog ownership statistics.

Cats

Cats rank second by household count at 47 million households (2024), but they close the gap on total population thanks to multi-cat homes. The US is home to roughly 74 million pet cats, with cat-owning households averaging 2 cats each per APPA data. Cat owners are more likely than dog owners to have multiple pets of the same species.

Cat ownership has grown 29% since 2000, outpacing dogs in percentage terms per APPA historical data. Indoor-only cats now make up around 63% of the total (2024), a shift driven by veterinary recommendations and municipal ordinances. Indoor cats live 12–18 years on average, compared to 5–8 years for outdoor cats.

The cat market has evolved beyond basic care. Premium and grain-free cat foods now represent 35% of all cat food sales, up from 12% in 2010. Automatic litter boxes, interactive toys, and subscription treat boxes have created an accessories market that barely existed fifteen years ago. Cat cafés have spread to over 100 US cities, normalizing cat culture in urban areas.

One distinctive feature of cat ownership is regional concentration. The Northeast and Pacific Northwest have the highest cat-to-dog ratios. Vermont, Maine, and Oregon all have more cats than dogs per household. Our cat ownership statistics page covers breed trends, regional differences, and annual costs in detail.

Fish

Freshwater fish are the most popular pet in America by sheer population count. An estimated 139 million freshwater fish live in US homes (2024), spread across 11.8% of households per APPA. The average freshwater aquarium holds about 12 fish, which explains why a relatively small ownership base produces such large numbers.

Saltwater fish add another 18 million to the total per APPA's 2024 survey. Only 2.3% of households keep saltwater tanks, but those who do maintain an average of 11–12 fish. Saltwater setups cost significantly more — initial equipment runs $500–$2,000 compared to $100–$300 for freshwater. Ongoing costs differ too: saltwater hobbyists spend roughly $400–$800 per year on maintenance, salt mixes, and livestock.

Fish ownership has declined about 12% since its peak in the early 2010s. Industry observers point to the time commitment of tank maintenance and the rise of low-maintenance pets like reptiles as contributing factors. The COVID-19 pandemic briefly reversed the decline as homebound Americans took up aquarium keeping, but the bump proved temporary.

Despite the overall decline, the aquarium hobby has gotten more sophisticated. Smart controllers that automate lighting, temperature, and water chemistry now account for 22% of aquarium equipment sales, up from 5% in 2015. The planted tank and aquascaping communities have grown on platforms like YouTube and Reddit, attracting a younger demographic that treats fish keeping as a design hobby rather than a traditional pet-keeping activity.

Birds, Reptiles, and Small Mammals

Birds, reptiles, and small mammals each occupy roughly 4.5% of US households — about 6 million homes per category. Despite similar ownership rates, population counts differ because of varying per-household averages.

Bird owners tend to keep the most animals per household, with parakeets and cockatiels leading by volume. Larger parrots like African Greys and Macaws are less common but represent outsized spending — a single African Grey can cost $1,500–$3,500, and their 40–60-year lifespan creates a decades-long financial commitment.

Reptile ownership has grown steadily over the past decade, fueled in part by social media exposure. Ball pythons, leopard geckos, and bearded dragons rank as the three most popular reptile species. The reptile segment skews younger than other pet categories: 38% of reptile owners are under 35, compared to 28% for dog owners. TikTok and Instagram have driven interest in less conventional species like blue-tongued skinks and crested geckos.

Small mammals — a category spanning hamsters, guinea pigs, rabbits, and ferrets — remain popular as starter pets for families with children. Rabbits are the fastest-growing segment within small mammals. Rabbit advocacy groups have successfully pushed for house rabbit adoption in many metro areas, positioning rabbits as indoor companions rather than outdoor hutch animals. The average rabbit owner now spends $600–$1,000 per year on their pet, roughly on par with cat ownership costs.

Pet Ownership by Generation

Millennials own more pets than any other generation in the United States. Generational differences in pet ownership reflect life stage, housing type, income, and cultural attitudes toward animals. The gap between generations is not just about how many pets people own — it shapes what they buy, how they care for their animals, and what they expect from veterinarians and retailers.

For a deeper look at how age, income, and household composition shape pet ownership, see our pet ownership demographics report.

Millennials Lead Pet Ownership

Millennials own pets at a rate of 73%, making them the most pet-owning generation in US history. They account for 35% of all pet owners nationwide. Among millennials who own homes, the rate jumps to 89%, suggesting that housing access is a key driver of the gap between millennials and older generations.

This generation popularized the term "fur babies" — and the data backs up the sentiment. A full 95% of millennial pet owners consider their pets to be family members, according to APPA. That attitude shows up in spending: millennials are more likely than older generations to buy premium food, invest in pet insurance, and pay for services like dog walking and pet-sitting.

Millennials also delay traditional milestones like marriage and parenthood at higher rates than prior generations. Pets fill a caregiving role in the interim. Nearly 40% of millennial pet owners say they got their first pet before having children. Mental health awareness plays a role too — 78% of millennial pet owners say their pet helps them manage stress or anxiety, compared to 62% of baby boomers.

The millennial influence on the pet industry extends beyond ownership rates. This generation drove the clean-label movement in pet food, demanding ingredient transparency and human-grade formulations. They account for 60% of direct-to-consumer pet brand revenue and are twice as likely as baby boomers to subscribe to a pet product delivery service.

Gen Z: The Emerging Pet Generation

Gen Z owns pets at a rate of roughly 60%, and that number is climbing fast. This generation is just now entering peak pet-acquiring years — finishing school, starting careers, and moving into their own housing. By 2030, industry analysts expect Gen Z to rival or exceed millennial ownership rates.

Social media is reshaping what Gen Z adopts. Platforms like TikTok and Instagram have boosted interest in exotic and unconventional pets. Reptile and amphibian ownership among Gen Z runs about 30% higher than among millennials at the same age. Hedgehogs, axolotls, and ball pythons have become aspirational pets in a way that would have seemed unlikely a decade ago.

Gen Z also shows distinct purchasing behavior. They research products online before buying at twice the rate of baby boomers. They favor direct-to-consumer pet brands and subscription services over big-box retail. And they are more likely to adopt from shelters — 34% of Gen Z pet owners acquired their most recent pet through a rescue organization.

Housing remains the biggest constraint for Gen Z pet ownership. With homeownership rates at historic lows for adults under 30, many Gen Z renters face pet restrictions and size limits. Cities with renter-friendly pet policies — Portland, Austin, Denver — show measurably higher Gen Z ownership rates than markets with restrictive norms.

Financial pressure also shapes species choices. Gen Z is more likely than other generations to choose cats, fish, or reptiles over dogs, partly because of lower upfront and ongoing costs.

How Much Do Americans Spend on Pets?

Americans spent $158 billion on their pets in 2024, according to APPA. That figure is projected to reach $165 billion in 2025. Pet industry spending has more than doubled since 2013, when the total was $55.7 billion. The US pet market is now larger than the combined revenue of the NFL, NBA, MLB, and NHL.

The average dog owner spends about $1,500–$2,000 per year on their pet. Cat owners spend $900–$1,200. These averages mask wide variation: a healthy young cat on budget food costs far less than a senior dog with chronic health issues on prescription diets and specialty medication. First-year costs run especially high — new puppy owners spend an average of $3,000–$4,500 when factoring in spay/neuter surgery, initial vaccinations, supplies, and training.

Spending by Category

Food and treats dominate pet spending, taking 43% of the total. Veterinary care claims the second-largest share at 22%. Supplies, live animals, and over-the-counter medicine together account for 26%.

The "other services" category — which includes grooming, boarding, training, pet-sitting, and dog walking — is the fastest-growing segment. It has tripled since 2015, driven by urbanization, dual-income households, and the normalization of professional pet care. Dog walking alone is now a $1.5 billion market. Pet boarding and daycare facilities have grown 40% since 2018.

Veterinary costs have risen sharply over the past decade, outpacing general inflation by roughly 2–3 percentage points annually. Emergency vet visits now average $800–$1,500. Routine annual checkups run $200–$400 for dogs and $150–$300 for cats. Dental cleanings — often the single most expensive routine procedure — cost $500–$1,200 depending on the animal's size and the complexity of the work. Our veterinary cost statistics page tracks these trends in detail.

Pet insurance has emerged as a fast-growing response to rising vet costs. The North American pet insurance market surpassed $4 billion in gross written premiums in 2024, covering roughly 5.5 million pets. Penetration remains low at about 4% of US pets, compared to 25–40% in the UK and Sweden. The gap suggests significant room for growth. For more, see our pet insurance statistics.

Historical Spending Growth

US pet industry spending has grown every single year for more than three decades. Even during the 2008–2009 recession, spending increased — a fact that cemented the industry's reputation as recession-proof. The COVID-19 pandemic accelerated growth dramatically, with spending jumping 37% between 2019 and 2022.

The jump from $72.6 billion in 2018 to $103.6 billion in 2020 marks the pandemic effect. Millions of Americans adopted pets during lockdowns, and existing owners spent more on premium products while working from home. Spending growth has decelerated since 2022 but remains above pre-pandemic trend lines. Annualized growth ran about 8% between 2022 and 2024, down from 15% during the pandemic years but still well above the historical average of 5–6%.

E-commerce now accounts for roughly 36% of pet product sales, up from 18% in 2019. Chewy, Amazon, and Walmart dominate online pet retail. The shift has pressured brick-and-mortar pet specialty stores, though Petco and PetSmart have countered by expanding veterinary services and in-store experiences.

Pet Ownership Trends Over Time

Pet ownership in the US has grown roughly 20% since 1988, rising from 56% of households to 67% in 2024. The trajectory has not been linear. Ownership climbed steadily through the 1990s and 2000s, peaked at 68% around 2012, dipped slightly, and then stabilized near 67%.

Species-level trends diverge from the overall pattern. Dog ownership has climbed 21% since 2000. Cat ownership has grown even faster at 29%. Fish ownership, by contrast, has fallen about 12% from its peak. Reptile and small mammal ownership have both ticked upward, though they remain niche categories at under 5% of households each.

The pandemic temporarily spiked ownership to near-record levels in 2020 and 2021. Shelters reported unprecedented adoption rates, breeders faced months-long waitlists, and puppy prices surged 30–50% in some markets. By 2023, some of that surge had reversed. Shelters in several states reported rising intake numbers as pandemic adopters returned animals. But the overall ownership rate held steady, suggesting most pandemic pets stayed in their homes.

Several structural factors support continued stability or modest growth. The US household count continues to rise. Millennials and Gen Z — the two most pet-friendly generations — are entering their highest-income years. Remote and hybrid work arrangements, now permanent for roughly 30% of knowledge workers, remove a traditional barrier to pet ownership. The counterforces are housing costs and urbanization, both of which correlate with lower ownership rates.

Pet Ownership by State

Wyoming has the highest pet ownership rate in the nation at approximately 72% of households. Rural states dominate the top of the rankings, while dense urban areas and island states fall to the bottom.

The bottom of the list tells an equally clear story about how housing density and cost affect pet ownership.

The pattern tracks with housing type and cost. States with more single-family homes and lower housing costs have higher ownership rates. Dense apartment markets with pet restrictions and high rents suppress ownership. Hawaii's low rate also reflects strict quarantine laws that discourage pet transport to the islands.

State-level data reveals dog-vs-cat preferences too. Southern and mountain states lean heavily toward dogs. The ratio in Wyoming is roughly 3 dogs for every 2 cats. Northeastern states have more balanced ratios, and a few — Vermont, Maine, and Massachusetts — tilt toward cats. Climate, property size, and cultural norms all play a role.

For the complete 50-state breakdown with dog-vs-cat splits, per-capita spending, and metro-level data, see our pet ownership by state page.

Pet Ownership Around the World

The United States leads the world in total pet spending and total number of pets, but several countries outpace it in household ownership rates. Australia tops the global rankings at 69% of households with pets, followed by the US at 67% and the UK at 57%.

Regional preferences vary sharply. Germany has nearly twice as many cats as dogs. Australia, the UK, and North America lean toward dogs. In parts of Southeast Asia and Latin America, stray and community dogs complicate ownership statistics because the line between "owned" and "community-fed" animals blurs. The World Health Organization estimates 200 million stray dogs worldwide, a population that does not appear in pet ownership surveys.

Globally, an estimated 500 million dogs and 400 million cats live as pets. The pet care market outside the US is growing faster in percentage terms, especially in China, Brazil, and India. Rising incomes are driving first-time pet ownership among the urban middle class in these markets.

China's pet market alone is projected to exceed $50 billion by 2027, up from roughly $30 billion in 2022. Brazil has the third-largest pet population in the world after the US and China, with an estimated 55 million dogs and 40 million cats.

The UK's PDSA Animal Wellbeing Report from 2024 provides some of the most detailed per-country data available. It estimates 13 million dogs and 12 million cats in British homes. UK pet spending reached £8.8 billion in 2024, or roughly £1,000 per pet-owning household. For country-by-country data, see our pet ownership by country report.

Pet Adoption vs Purchasing

About 23% of dogs and 31% of cats in US homes were acquired from shelters or rescue organizations, according to APPA. The adoption movement has transformed animal welfare outcomes over the past two decades, but purchasing from breeders and pet stores still accounts for the majority of pet acquisitions.

Roughly 6.3 million animals enter US shelters every year, according to the ASPCA. Of those, 4.1 million are adopted into homes. The remaining animals are returned to owners, transferred to other organizations, or — in the most difficult cases — euthanized.

Euthanasia rates have dropped dramatically. In 2000, roughly 2.6 million shelter animals were euthanized each year. By 2024, that number had fallen to approximately 720,000 — a 72% decrease over 24 years. Spay/neuter programs, the rise of rescue organizations, social media adoption campaigns, and shifting public attitudes all contributed to the decline.

The "adopt don't shop" movement gained cultural momentum in the 2010s. Several major cities — including Los Angeles, San Francisco, and Phoenix — have banned or restricted the sale of commercially bred dogs and cats in pet stores. These policies push consumers toward shelters and reputable breeders who sell directly.

Still, demand for specific breeds remains strong. Roughly 34% of dogs come from breeders, according to APPA survey data. French Bulldogs, Golden Retrievers, and Labrador Retrievers top the breeder-purchase lists. The tension between adoption advocacy and breed demand continues to shape the market.

Shelter demographics have shifted over the past decade. Large dogs and pit bull-type breeds remain overrepresented in shelters, while small and medium purebreds are adopted quickly — often within 24–48 hours of listing. Cats continue to enter shelters at higher rates than dogs, though cat euthanasia rates have dropped faster thanks to trap-neuter-return programs for community cat colonies.
