An estimated 65.1 million households in the United States owned at least one dog according to a 2023/24 pet owners survey, making them the most widely owned type of pet across the U.S. at this time. Cats and freshwater fish ranked in second and third places, with around 46.5 million and 11.1 million households owning such pets, respectively.

Freshwater vs. salt water fish

Freshwater fish spend most or all their lives in fresh water. Fresh water’s main difference to salt water is the level of salinity. Freshwater fish have a range of physiological adaptations to enable them to live in such conditions. As the statistic makes clear, Americans keep a large number of freshwater aquatic species at home as pets.

American pet owners

In 2023, around 66 percent of all households in the United States owned a pet. This is a decrease from 2020, but still around a 10 percent increase from 1988. It is no surprise that as more and more households own pets, pet industry expenditure has also witnessed steady growth. Expenditure reached over 136 billion U.S. dollars in 2022, almost a sixfold increase from 1998. The majority of pet product sales are still made in brick-and-mortar stores , despite the rise and evolution of e-commerce in the United States.

Active Dog Licenses.

All dog owners residing in NYC are required by law to license their dogs. The data is sourced from the DOHMH Dog Licensing System (https://a816-healthpsi.nyc.gov/DogLicense), where owners can apply for and renew dog licenses. Each record represents a unique dog license that was active during the year, but not necessarily a unique record per dog, since a license that is renewed during the year results in a separate record of an active license period. Each record stands as a unique license period for the dog over the course of the yearlong time frame.

Cat and dog owners do not only differ in the type of pets they choose but also the leisure activities that they take part in. According to the source, when looking at data from 2017 and 2018, dog owners were more likely to engage in active activities such as exercise, jogging, and going to sporting events. Comparatively, cat owners were more interested in reading books, surfing the internet, and listening to music.

During a survey conducted in 2024, it was revealed that millennials represented the biggest share of pet owners in the United States (32 percent), followed in second place by Generation X (24 percent). Baby Boomer's came in third, representing some 24 percent of pet owners. Pet ownership in the United States Despite some fluctuations, household penetration rates for pet ownership in the United States have generally increased over the years, going from 56 percent in 1988 to approximately 66 percent in 2023. With millennials constituting the largest group of pet owners in the United States, they also constituted the generational group that planned to spend the most on their pets during the holidays in 2020, with an average spending of 51 U.S. dollars, compared to only 28 U.S. dollars of average planned spending on pets for Baby Boomers. Pet expenditure in the U.S. Pet food and treats constituted the highest selling category for pet products in the United States, with total food and treats sales reaching 58.1 billion U.S. dollars in 2022. Vet care and product sales were the second biggest pet market category that year, generating around 35.9 billion U.S. dollars in sales. Generally, average annual pet expenditure was higher for dog owners than for cat owners across all pet market categories in 2020.

Sixty six percent of households in the United States owned one or more pets in 2023. Household penetration rates for pet-ownership have increased by 10 percent since the beginning of the survey period in 1988.

What kinds of pets do Americans prefer?

There were estimated to be around 65 million dog-owning households in the United States according to a recent survey, making dogs the most popular kind of pets in American homes. Cats and freshwater fish ranked in second and third places, respectively. Horses and saltwater fish were the least popular types of animals to keep, with around 2.2 million households owning each type of pet.

How much do Americans spend on their pets?

Total pet industry expenditure reached around 136.8 billion U.S. dollars in 2022, an increase on the previous year. As well as regular expenses such as food and vet costs, households were estimated spend around 1.7 billion U.S. dollars on Valentine's Day gifts for their pets in 2023.

IntroductionAlthough multiple studies have explored behavioral changes in pets during the strict lockdown of the COVID-19 pandemic between May and July 2020, this longitudinal study uniquely investigated the phases beyond strict lockdown. The primary objective of this research was to evaluate the pandemic’s impact on pet behavior.MethodsTo achieve this goal, we conducted an online survey, completed by pet owners residing in the United States between June 2020 (including retrospective data for February and April 2020) and December 2021. The study encompassed four distinct pandemic phases: Pre-pandemic (data collected retrospectively), Strict lockdown, Prolonged lockdown, and Re-opening.Results and discussionThe data collected from surveys completed by 3,278 pet owners across one to six time points revealed declining trends in all investigated behavior problems of both dogs and cats. Concurrently, human-animal interaction activities also showed variations across different COVID-19 phases. The association between human-animal interactions and the occurrence of behavior problems underscored the importance of not only exercise quantity but also adherence to consistent schedules, particularly for dogs, in mitigating behavior problems. Interestingly, among cats, sleeping outside the bedroom was associated with a reduced occurrence of aggression, anxiety, fear, and physiological behavior changes. However, sleep location displayed limited or no association with behavior problems in dogs. In summary, this study highlights the importance of tailoring interventions to the unique needs of each species through human-animal interactions to mitigate the occurrence of behavioral problems and enhance human-animal relationships.

Animal shelters aim to divert intake by encouraging pet retention in homes (e.g., support services) or through alternative methods of surrender (e.g., self-rehoming); however, it remains unclear what factors contribute to decisions to seek pet support services, as well as select different methods to surrender a pet. Using a sample of 452 U.S. and Canadian public members who rehomed a dog or cat within the past five years, the present study identified groups of pet owners who share similar patterns of responses to surrender circumstances using latent class analysis. The model revealed three heterogeneous classes of surrendering pet owners distinguished largely by the reason for surrender and the length of ownership. Comparisons revealed differences across classes regarding the proportion of respondents, the pathways used to surrender, and the concerns reported by respondents during surrender. Qualitative analysis revealed that respondents wanted or sought a variety of different support services, including behavioural support, part-time care, and veterinary care. Future research should consider the heterogeneity in surrender decision-making when addressing issues of intake diversion from animal shelters.

1. The number of alien reptiles and amphibians introduced and established worldwide has been increasing over the last decades. The legal pet trade is the now the dominant pathway by which individuals of these species arrive in their non-native locale. Despite its importance, pet trade pathway specific factors that influence the release (introduction) of exotic reptiles and amphibians have not yet been examined.
2. To address this gap, we set out to identify broad-scale and easily measured biological and economic factors that influence the release of these exotic pets by their owners. We hypothesize that biological factors reflect the cost of care and economic factors reflect the value owners place on their pet, both of which can influence the probability a pet is released. We collected life history and economic data on the 1722 species of reptiles and amphibians sold within the US as pets over the last 18 years. We also compiled a list of pet-trade attributed releases in the US (i.e. all free-living species regardless of whether they successfully established). We then used boosted regression trees to correlate species release status to their life history traits and economic attributes (r2 = 0.51, AUC = 0.89).
3. We found that species with a high probability of being released were imported at higher quantities over our period of record, have a relatively large adult mass, and commanded cheaper retail prices. Quantity imported and price interact with longevity and adult mass to produce non-linear increases in release probability. The most important interaction revealed that large-bodied species imported in high quantities have a three times higher release probability compared to large-bodied species imported in lower quantities.
4. Policy implications. Our results provide much needed guidance toward targeting exotic pet reptile and amphibian species that are at a high risk of being released. In particular, species that are both prevalent in the pet trade and are large-bodied or long-lived have the highest probability of being released. This will aid in developing education and policy solutions aimed at decreasing the rate at which these pets are released, thus curtailing the invasion process before these species can establish and impacts can occur

Data on flea parasitism and annual re-encounters of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies along an elevation gradient from 2,645 m to 2,873 m. Upon first capture each year, we anesthetized each prairie dog and fleas on its body and combed the prairie dog as thoroughly as possible for 30 s to collect fleas. We recorded the age (juvenile/adult), sex, and mass (nearest 5 g) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent identification. We indexed each prairie dog's body condition as the ratio between its weight and hind-foot length (nearest 0.10 cm) (weight:foot). Prairie dogs were allowed to recover from anesthesia and released at their trapping locations. Precipitation data for individual prairie dog colonies each year (February through September) are from the Parameter-Elevation Relationships on Independent Slopes Model (Daly et al. 2008; http://www.prism.oregonstate.edu/). The first set of data, Awapa UPD Fleas, includes data on the abundance of fleas on individual Utah prairie dogs. Each line of data is from an individual animal. Data include Utah prairie dog Age and Sex, prairie dog Condition, abundance of Fleas on the prairie dog, precipitation of the prior year (PriorPRISM), and precipitation of the current year (CurrentPRISM). The second set of data, Awapa UPD Reencounter, includes data on annual reencounters of individual Utah prairie dogs. Each line of data is for an individual prairie dog in a given annual interval; an animal must have been captured at the start of an interval to be included in that interval (e.g., a prairie dog captured in 2013 but not captured in 2014 was included in the interval 2013–2014 but was not included in the interval 2014–2015). The response variable (Reencounter) was binomial (e.g., a prairie dog captured in 2013 and 2014 but not in 2015 received a response of 1 for the interval 2013–2014 and a value of 0 for the interval 2014–2015). Predictor variables included: PriorPRISM, CurrentPRISM, prairie dog Age and Sex, prairie dog Condition, and flea parasitism of the prior year (expressed as detection/non-detection of at least 1 flea on a prairie dog in the prior year = FleaPrev). Data also include a information on trapping effort (i.e., number of trap days on a given colony) in the current year. Funding and logistical support were provided by the U. S. Geological Survey (USGS), Western Association of Fish and Wildlife Agencies, and Colorado State University. This research was also supported by Grant/Cooperative Agreement Number G14AC00403 from the USGS and Grant number RC-2634, Department of Defense Strategic Environmental Research and Development Program.
