How Pet Preference Links to the Big Five: A Research-Based Guide

Are You a Dog Person or a Cat Person? What Your Pet Choice Says About Your Personality

“Are you a dog person or a cat person?” is one of those questions people answer like it reveals something deep — and, it turns out, it actually does, a little. Research on the Big Five personality model finds a small but consistent difference between people who call themselves dog people and those who call themselves cat people. In the largest study on the topic, dog people scored higher on extraversion, agreeableness, and conscientiousness, and lower on neuroticism and openness than cat people. The gaps are modest (effect sizes around 0.27–0.40), so pet preference is a weak signal of personality rather than a diagnosis — but the pattern has shown up across multiple independent samples. Below we walk through what each side tends to look like, why the link probably exists, and what it can’t tell you.

What the landmark study actually found

The clearest evidence comes from Gosling, Sandy, and Potter (2010), published in the journal Anthrozoös. They recruited 4,565 people through a public website and had each complete the Big Five Inventory, a standard questionnaire measuring the five broad dimensions of personality. The five factors — often called the Five Factor Model or OCEAN model — are openness, conscientiousness, extraversion, agreeableness, and neuroticism, the dimensions researchers use to summarize how people differ from one another. Participants also labeled themselves a dog person, a cat person, both, or neither.

Dog people came out ahead on extraversion (effect size d = 0.40), agreeableness (d = 0.33), and conscientiousness (d = 0.27), and behind on neuroticism (d = 0.30) and openness (d = 0.27). These differences held even after the researchers controlled for the fact that women own cats at slightly higher rates than men, so the pattern isn’t just a side effect of who happens to own which pet. A 2024 study by Oliva and Baines, also in Anthrozoös, found the same neuroticism gap in 329 actual pet owners and added a twist: dog owners scored higher on resilience.

Dog people: outgoing, dutiful, and easy to get along with

The dog-person profile maps onto traits that fit life with a social, routine-loving animal. Extraversion is the tendency to seek stimulation and company from others; dog people’s higher score fits the dog’s role as a built-in excuse to get outside and meet people on walks. People high in this dimension tend to be energetic, talkative, and motivated by social connection — the kind of owner a dog’s pack mentality suits.

Agreeableness — the disposition toward cooperation, trust, and warmth — also runs higher in dog people. Conscientiousness, the trait behind organization, self-discipline, and planning, is the third dog-person strength, and it lines up with the structured care dogs need: fixed feeding times, walks, and training. A 2015 study by Alba and Haslam added that dog people score higher on social dominance orientation and competitiveness, a reminder that the profile isn’t uniformly gentle.

Cat people: open, curious, and a bit more sensitive

The cat-person pattern leans the other way on two dimensions. Openness to experience describes curiosity, imagination, and a taste for novelty and unconventional ideas; cat people’s higher score fits the independent, low-maintenance companion that asks little of a free-ranging schedule. People strong in openness tend to be creative, introspective, and comfortable doing things their own way — traits that sit comfortably with a pet that entertains itself.

The other cat-person marker is neuroticism, the tendency toward anxiety, mood swings, and emotional reactivity. Neuroticism here is a spectrum of emotional stability, not a flaw; some research even links it to greater vigilance about health and stronger care for others. It’s worth saying plainly: scoring higher on neuroticism does not make someone “crazy” or broken. It mainly means feelings run closer to the surface, which is a mixed bag rather than a verdict.

Does owning the pet shape the personality — or the other way around?

This is the question the studies can’t fully answer. Because the research is correlational, we can’t tell whether a personality draws you to a pet, whether living with the pet nudges your traits, or whether both are shaped by a third factor like lifestyle. Reevy and Delgado (2015) found that people who liked both animals looked more like dog people on extraversion and agreeableness but stood out on openness, suggesting the split isn’t a clean either-or. Bao and Schreier (2016) later replicated the neuroticism and conscientiousness gaps using people who actually owned the pets, not just those who identified with them.

A separate line of work looks at direction: Stanley Coren’s 2000 survey of 6,149 people found dog owners more extroverted and accepting, cat owners more introverted. Most psychologists read this as self-selection — you pick the companion that matches the life you already live — rather than the animal rewriting your personality. Either way, the link is real enough to be worth noticing, and loose enough that no one should reorganize their identity around it.

What pet preference can’t tell you

It’s tempting to turn a fun finding into a label, so a few cautions matter. First, the effect sizes are small; the overlap between dog and cat people is far larger than the difference, so many cat people are outgoing and many dog people are introspective. Second, the “crazy cat lady” stereotype is both unkind and unsupported — higher neuroticism is a normal distribution, not a diagnosis. Third, practical limits like allergies, housing, and childhood pets explain a lot of ownership that has nothing to do with personality.

None of this means the pattern is useless. Used lightly, pet preference is a low-stakes doorway into self-reflection — a way to notice which traits you lean on without turning anyone into a caricature. That’s the value of personality psychology done well: it describes tendencies, not destinies.

How to use this for self-awareness

If the dog-versus-cat split made you nod, the next step is to see the full picture rather than one proxy. A short, well-validated assessment gives you a profile across all five dimensions at once, which is more informative than guessing from a single preference. If you want a quick read on where you land, a free Big Five and 16-type assessment at personalitree.com takes about ten minutes and lays out your scores in plain language. Tools like personalitree.com make personality testing accessible without requiring a psychology degree, and they pair the Five Factor Model with the 16 personality types for people who like both lenses.

The useful takeaway isn’t “dog people are X.” It’s that the small things we’re drawn to — a pet, a hobby, a workspace — often echo the same traits a formal test would describe. Self-awareness grows when you connect those echoes instead of boxing yourself into one of them. Whether you’re team dog, team cat, or happily both, the personality behind the preference is the more interesting story.

Frequently asked questions

Are dog people really more extraverted than cat people?

Yes, on average. The 2010 Anthrozoös study found dog people scored higher on extraversion (d = 0.40), the largest gap in the dataset, and later surveys of actual owners found the same direction. The difference is a group average, not a rule — plenty of cat people are social and plenty of dog people are quiet.

Is it true that cat people are more neurotic?

In the research, cat people do score somewhat higher on neuroticism, and a 2024 study linked cat owners to lower resilience than dog owners. Neuroticism here means emotional sensitivity and reactivity, not incompetence or instability, and the effect is modest. It’s a tendency, not a label.

Does owning a dog or cat change your personality?

The studies are correlational, so they can’t prove direction. Most psychologists treat the link as self-selection: people choose pets that fit the life they already lead. There’s some evidence pets boost well-being, but no solid proof that a cat or dog reshapes your core traits.

Can a personality test predict whether I’m a dog or cat person?

Loosely. Because pet preference correlates with the Big Five, a test that places you high on extraversion and conscientiousness and low on openness makes a dog lean more likely, while the reverse nudges toward cats. The prediction is probabilistic, not certain, and “both” is a common and valid answer.

Which matters more — the Big Five or the 16 personality types?

The Big Five is the more researched framework and the one used in the dog-cat studies. The 16 personality types (Myers-Briggs) are popular and intuitive but less supported by evidence. For understanding pet preference specifically, the Five Factor Model is the better tool; the 16 types add a different, more narrative lens.
