Key sections will include the history behind this phrase, scientific research and criticisms, anecdotes and examples demonstrating this phenomenon, and analysis of the deeper social and psychological factors that may be involved. This lighthearted yet thought-provoking topic reveals interesting insights about human nature, relationships, and our connections with the animals around us.

History of the Saying

The saying “dogs look like their owners” has been around for over a century, with early documented usages dating back to the late 1800s. In his 1896 book “Household Pets”, ornithologist William Everitt Cram wrote: “the sagacious and observant have remarked that dogs, in the course of time, come to resemble their masters or mistresses” (Source).

References to dogs resembling their owners appeared in publications like Household Words and The Saturday Evening Post in the early 1900s. By the 1920s, it had become a common English saying as attested by multiple dictionaries and books quoting some version of “dogs look like their owners” or “dogs grow to resemble their masters.”

The adage highlighted the close relationships and daily interactions between dogs and their owners that supposedly caused them to grow alike. Over the decades, it evolved into a popular phrase used in everyday conversations, cartoons, comedy routines and more to teasingly suggest people subconsciously choose pets resembling themselves.

Scientific Research

Several studies have examined whether there is any validity to the claim that dogs resemble their owners. In a study published in the journal Anthrozoös, researchers photographed 45 dogs and their owners separately, and then asked observers to match the dogs with their owners based solely on physical appearance. The observers were able to match purebred dogs with their owners at a rate significantly above chance.

Another study published in the journal Perception also found that people could match photos of dogs and owners by facial features at a rate significantly higher than chance. The study concluded that humans may choose dogs who resemble themselves, perhaps through preferences based on personality traits and desired size/activity level.

While these studies show people can match dogs to their owners based on physical appearance at better than chance levels, the effect is still relatively small. More research is needed to understand if this is simply due to familiarity and environment, or if there are other factors causing dogs to resemble their caregivers.

Reasons for the Perceived Similarities

There are several possible explanations for why some dogs may resemble their owners.

One is selection bias. When choosing a dog, people may be unconsciously drawn to dogs that have physical traits or expressions that match their own. According to a study published in BBC Future, this effect seems strongest in male dog owners, who tend to choose dogs with wider faces similar to their own.

Another reason is unconscious synchrony in expressions and mannerisms. Dogs are very receptive to human social cues. According to research from Discover Magazine, over time dogs may mimic their owner’s facial expressions. This could lead them to develop similar wrinkles and make comparable expressions that increase their resemblance.

There are also theories that dogs and owners converge in appearance due to shared lifestyles and environments. Factors like diet, exercise, sunlight exposure, and stress levels may shape the aging process. Dogs who eat, sleep, play, and walk with their owners may develop comparable physical traits.

Anecdotes and Examples

There are many amusing anecdotes and examples of dogs bearing an uncanny resemblance to their owners. As dog owner Mark Twain famously quipped, “If you pick up a starving dog and make him prosperous he will not bite you. This is the principal difference between a dog and man.”

Celebrity examples abound, like Anderson Cooper and his dog Lily who share similar gray locks. As Cooper told People magazine, “I guess we do have the same color hair. I hadn’t really thought of that, but I guess it’s true.”

Reality star Lisa Vanderpump remarked of her Pomeranian Giggy, “He looks like me. He’s got this sort of screwed-up face.”

There are countless funny examples documented on social media. As one Twitter user posted with a photo of a man with his pup, “My colleague looks like his dog and I can’t stop staring.” Another owner snapped a selfie with his hound dog commenting, “My dog looks more like me than I do.”

The resemblances run deep, from hair color and style, facial expressions, and even matching outfits. As the old saying goes, dogs start to look like their masters, showing the power of companionship to influence appearance over time.

Criticisms and Skepticism

While many believe dogs strongly resemble their owners, some argue that this is an exaggerated or false perception. There are several reasons why people may see a false pattern of dogs looking like owners when no real correlation exists.

One argument against dogs resembling owners is that the claim relies heavily on anecdotal evidence. Just because some famous examples exist of owners and dogs looking alike, like Elvis and his dog Scatter, does not mean this is a widespread phenomenon. Limited statistical research has been done to back up the notion.

Additionally, critics point out that people tend to see patterns and connections where there are none. The cognitive bias of pareidolia leads the brain to interpret random images or shapes as significant. This could cause people to imagine a resemblance between a dog and owner when little actual similarity exists.

Selection bias also comes into play, as examples showing a resemblance between dog and owner are more likely to go viral or get media attention. Instances disproving the claim are less likely to be noticed or shared publicly.

Overall, while an owner and dog may sometimes bear a striking resemblance, many argue that the belief dogs strongly or consistently look like their owners is an exaggerated claim lacking statistical evidence. Examples certainly exist, but the tendency of the human brain to see patterns leads to perceiving connections that may not reflect reality.

Impact on Dog Adoption

There is some evidence that people are more likely to adopt dogs that they perceive as resembling them in some way. This phenomenon is known as the “matching hypothesis” in adoption preferences. One study found that potential adopters spent more time looking at dogs that had similar facial features and expressions to their own [1]. Seeing a resemblance seems to spark a deeper sense of connection and kinship with the dog.

However, it’s important that people keep an open mind when searching for a new canine companion. Focusing too narrowly on dogs that look like you means potentially missing out on your perfect match. Shelters are filled with dogs of all shapes, sizes, ages and breeds waiting to find loving homes. While perceived resemblance may play a role, the most important factors in successful adoption are compatibility of lifestyles and personalities. With so many homeless dogs needing families, people should consider all possibilities and avoid overlooking potential adoption candidates simply for lack of physical similarity. The right dog is out there for everyone.

Other Animal Resemblances

Beyond dogs and cats, some people claim that other pets and animals also come to resemble their owners over time. For example, there are anecdotes of pet birds mimicking their owner’s voices and personality quirks. Studies on chimpanzees have found some evidence that they may develop similar facial structures to humans they frequently interact with.

However, the evidence for owner-pet resemblance in other animals is much more limited compared to dogs and cats. While people may notice similarities through confirmation bias, rigorous scientific studies have not verified these effects across other species. Controlled experiments would be needed to properly test for similarities in personality, behavior, appearance, and other traits between owners and their exotic pets or livestock.

Overall, the dominant research focuses on potential psychological and social reasons that dogs and cats may come to resemble their caregivers. But more work is still needed to determine if this phenomenon extends to less common household pets like birds, rodents, reptiles, and fish. Similarities noticed by owners could also be coincidental rather than causative.

Pop Culture References

The saying that dogs look like their owners has become a prevalent trope in pop culture, with many references in movies, TV shows, books, songs, and art. Some examples include:

In Disney’s 1955 animated film Lady and the Tramp, Lady’s owners Jim Dear and Darling resemble the cocker spaniel in their hairstyles and facial features.

In an episode of The Simpsons titled “Two Dozen and One Greyhounds”, Mr. Burns adopts 25 greyhound puppies that resemble him in looks and behavior.

The music video for the song “Dogs” by Pink Floyd depicts various people with dogs that look uncannily like them through makeup and costumes.

The book cover illustration for Good Dog. Bad Dog. by Colin Dann shows a man and a misbehaving dog with similar shaggy brown hair and expressions.

The popular Twitter account @ fury pals highlights people’s submissions of photos with their pets who resemble them, often in humorous or exaggerated ways.

Overall, the trope that dogs eventually resemble their owners remains a common joke and artistic theme across many pop culture mediums.


In conclusion, the adage that dogs resemble their owners has persisted for decades, with various scientific studies conducted to investigate any potential validity behind the saying. While research has not found conclusive evidence to support the notion, some studies do point to possible contributing factors, like owners subconsciously choosing dogs that match their personality or appearance. Additionally, shared lifestyles and cohabitation may promote similar expressions and mannerisms between owners and pets over time.

Overall, it seems there is likely some degree of truth to the saying, though the extent and causes remain debated. The perception of uncanny resemblance in some owner-dog pairings may simply come down to our tendency as humans to see patterns, even in randomness. While it makes for an amusing topic of observation and speculation, there is no definitive proof that dogs and owners deliberately Select and morph into doppelgangers. The saying appears to contain elements of truth, but also exaggeration for the sake of a catchy phrase.

In the end, we love our dogs for their unique personalities, not their looks. And the strong bonds we form with our canine companions have less to do with appearance and more to do with the friendship, loyalty and unconditional love we share.
