Dogs have a 'social intelligence' and can use this along with their other senses to decide if the person arriving is unknown to you. Dogs' heightened sense of smell can pick up on strange body odors, the smell of fear or anxiety, and someone coming from a different neighborhood.
Dogs are able to identify, with ease, the scent of someone they recognize over the someone they have yet to meet. Even before an individual walks through the door, dogs have been alerted to who it is using their senses of smell and hearing.
They continually scan the expressions and movements of people they meet as a way to interpret and anticipate intentions. So, even friendly dogs will be able to tell the difference between a visit from a new Pet Sitter and an ill-intentioned intruder who is sneaking around outside.
Is It True That Dogs Can Smell Fear? The science is in, and the answer is a resounding YES—dogs can smell fear. Dogs have olfactory superpowers that can detect a human's emotional state by the scent that a human emits. That's right—you can't hide fear from dogs.
Studies have also highlighted that dogs do react favorably to the smell of their owner and their family. A dog is able to recognize the scent of their own family.
How far a dog smells depends on conditions such as wind and type of scent, but they have been reported to smell objects and people over 12 miles away. Dogs' olfactory systems work so well that they can be trained to pick up odors as little as a pictogram which is a trillionth of a gram.

Unlike humans, who experience the world visually, dogs detect changes to their environment, including who has been there and for how long, through their impeccable sense of smell.
When a dog is detecting sickness in their human, there are some tell-tale signs you can read simply from your doggy's body language. The dog will raise his snoot and tilt his head when he is trying to concentrate on the things, sounds and smells around him. He will be relaxed, yet alert.
Recent studies say yes. They can smell stress, depression, sadness and grief. Dogs can smell the production of various hormones and brain chemicals. Dogs can smell the rise and fall of serotonin (a brain chemical associated with depression).
Some dogs suffer extreme fear of strangers. They cower, tremble, and try to hide from any new person they meet. While it's not unheard of for dogs to be afraid of strangers, the ideal reaction is one of open friendliness, not hiding or running away.
Dogs can sense when someone is a bad or good person. Your dog may not know the moral decisions a person has made, but he can pick up on signs of nervousness, fear, anger, and danger. Dogs notice specific things about humans that even other humans are not aware of.
Many dogs are fearful around people they don't know well. Some people automatically assume these dogs have been abused in the past. Usually, this is NOT the case. Most of the time, if a dog fears strangers, she has simply been under-socialized to them.
So, dogs know a person's individual smell and when illness changes that smell, dogs can notice that, too. Even humans can observe the scent of sickness with some health problems. For example, diabetic ketoacidosis can cause fruity or acetone-smelling breath.
Signs a Dog Can Sense A Burglar
Dogs have stupendous hearing powers and no matter how quiet a robber might be, the family woofer is likely to hear them. It seems your pet Papillon or Retriever could be the most efficient security there is. A barking mutt is a scary proposition for a thief trying to raid your home.
The short answer is yes, most dogs do have favorite people. As social animals, dogs tend to be happiest and healthiest with company. And because domesticated pets depend on their people to meet virtually all their needs—food, shelter, and even access to the bathroom—these dog-human bonds are strong.
Medical Reasons Dogs May Stink
Secondary yeast or bacterial infections on the skin or inside the ears remain the most common medical reasons dogs might smell awful. Allergies often begin the process, which leads to scratching and licking that open the door for infections.
When dogs sniff people they are gaining all sorts of information about us. They know if we are familiar or a stranger. They know which scents we have attracted while we've been away. They know if we are experiencing changes in hormones, such as those that occur during pregnancy.
Dogs rely heavily on their noses and have a much more sensitive sense of smell than humans, so they're naturally more attracted to sweaty parts of the body, like the groin area. A dog will sniff your crotch simply because they are curious about you and want to learn more about your age, sex, and mood.
At the top of the list? Citrus. Most dogs can't stand the taste and smell of oranges, lemons, and grapefruit. Here's why — plus, how to use their dislike of citrus to your advantage.
They're very good at picking up on subtle cues like reading body language, changes in the environment, and listening to sounds. And not just your own signals, but maybe the sound of a neighbor's car that starts up a few minutes before you arrive home.
The chemical aromas identify gender and mood, and even communicate what a dog likes to eat. By simply smelling, a dog can determine if a new friend is male or female, happy or aggressive, or healthy or ill.
