Dogs quickly form opinions about people, sometimes within seconds of meeting them. While some individuals get an excited greeting, others receive wary stares or cautious retreat. But what determines a dog’s preference? Is it scent, past experiences, or instinct? Dogs are incredibly perceptive, picking up on subtle cues that humans overlook. From body language to emotional energy, various factors influence why your pup bonds with some people while remaining suspicious of others. Their ability to read people is almost like a superpower, making their preferences fascinating and mysterious.
The Smell of a Person Says More Than Words

Dogs experience the world primarily through their noses, which are far more powerful than human noses. A person’s scent tells a dog a lot about them—where they’ve been, what they’ve eaten, and even how they feels. A dog may find the scent off-putting if someone smells like other animals, has strong perfumes, or even uses certain chemicals. On the other hand, if a person smells familiar or comforting, like another dog lover or someone who works with animals, they’re more likely to be greeted with enthusiasm.
Body Language Can Make or Break a First Impression

Dogs are experts at reading nonverbal cues, often noticing things that humans overlook. Someone who moves suddenly, aggressively, or overly enthusiastically can make a dog uneasy. Direct eye contact, stiff posture, or quick movements can signal a threat in a dog’s mind. Conversely, a person with relaxed body language, a gentle approach, and a nonthreatening stance is more likely to be accepted. Some people naturally give off “dog-friendly” vibes, while others unknowingly make dogs nervous.
The Tone of Their Voice Speaks Volumes

While dogs may not understand every word, they are highly attuned to tone. A deep, harsh voice can come across as intimidating, making a dog wary or even fearful. High-pitched, friendly tones are more inviting and often elicit tail wags and happy reactions. People who naturally use soft, cheerful tones tend to be more liked by dogs, while those with loud, commanding, or abrupt voices might struggle to win a pup’s affection.
Past Experiences Shape a Dog’s Preferences

Just like humans, dogs are influenced by their past experiences. If a dog had a negative encounter with someone who had a similar appearance, scent, or mannerisms, they may carry that association forward. For example, if a dog was once mistreated by a tall man wearing a hat, they might be wary of all tall men in hats. On the other hand, positive experiences—such as being treated kindly by a person with a certain look or voice—can create lifelong positive associations.
Some People Just Have “Dog Energy”

Dogs have an instinct for sensing energy, and some people naturally give off an aura that dogs either love or dislike. Calm, confident people tend to attract dogs, while those who are nervous, anxious, or overly excitable may make them uneasy. Dogs pick up on emotions easily, so if someone is fearful of dogs, the dog will likely sense it and react accordingly. People with a relaxed, friendly demeanor are more likely to win a dog’s trust.
Their Clothes and Accessories Matter More Than You Think

It might sound strange, but what a person wears can influence how a dog reacts to them. Hats, sunglasses, bulky coats, or masks can make someone look unfamiliar or even threatening in a dog’s eyes. Some dogs may have had bad experiences with people wearing certain types of clothing, leading to a negative association. On the flip side, a person wearing casual, familiar-smelling clothing may seem more approachable to a dog.
Dogs Can Sense Health Conditions and Hormones

Dogs have an incredible ability to detect changes in a person’s body, including hormonal shifts, illnesses, and even stress levels. Some dogs react differently to people with certain medical conditions, such as diabetes or epilepsy, because they pick up on scent changes. Pregnant individuals or those going through hormonal fluctuations may also attract extra canine attention—or avoidance. A person’s internal chemistry may be sending signals to a dog that humans aren’t even aware of.

Dogs communicate a lot through eye contact, and how a person looks at them can make all the difference. While prolonged, direct staring can be interpreted as a challenge or threat, soft and relaxed eye contact signals friendliness. Some people naturally engage in gentle, reassuring eye contact, while others unknowingly make dogs uncomfortable with intense staring. Dogs are quick to pick up on these nuances and react accordingly.
Some Dogs Are Just Picky About Their People

At the end of the day, some dogs simply have preferences for the kind of people they like or dislike. Just like humans, dogs have unique personalities and quirks. Some may favor people who remind them of a beloved past owner, while others may prefer individuals who give them space rather than overwhelming affection. While science explains much of a dog’s behavior, sometimes, their choices come down to personal preference—because, after all, every dog has their own idea of the perfect human.
The Secret Doggy Judging Panel Is Always Watching

Dogs may not hold official trials, but they have an impressive way of judging people. Whether it’s detecting scents, sensing emotions, or reading body language, they have an almost supernatural ability to decide who they trust. Some reasons make perfect sense, while others remain a mystery that only dogs understand. If your pup prefers certain people over others, their internal judging panel is always at work—silently deciding who earns VIP cuddles and who gets the suspicious side-eye. Their instincts may be uncanny, but they rarely get it wrong!
