According to a recent study by researchers at Queens University Belfast, dogs can detect stress through human sweat and breath.
36 people from Belfast, including Treo, Fingal, Soot, and Winnie, participated in the study.
Sweat and breath samples were taken from participants before and after they completed a challenging math problem by researchers. Prior to and following the task, they rated their stress levels, and researchers only used samples where the subjects’ blood pressure and heart rates had risen.
The dogs were trained to find the right sample in a scent line-up by searching for it. The researchers then introduced the stress and relaxed samples, but at this point they were unsure if the dogs could detect a difference in odor.
Each dog in each test received samples from one person’s relaxed and stressed states, taken just four minutes apart. Each dog was able to correctly notify the researchers when a person’s stress level increased.
“The findings show that we, as humans, produce different smells through our sweat and breath when we are under stress, and dogs can tell this apart from our smell when we are relaxed — even if it is someone they do not know,” says Clara Wilson, a PhD student in the School of Psychology at Queens.
The study shows that canines can detect human stress without visual or aural cues. This study is the first of its kind, and it shows that dogs can detect stress just from breath and perspiration, which may be helpful when training service dogs and therapy dogs.
“It also adds to our knowledge of how dogs may interpret and interact with human psychological states and sheds more light on the human-dog relationship,” “.
Treo, a 2-year-old Cocker Spaniel, was one of the super sniffer dogs involved in the study. As the owner of a dog that thrives on sniffing, Helen Parks says, “We were delighted and curious to see Treo participate in the study.” Each week when we picked him up, we couldn’t wait to hear the results. He could navigate himself to the lab and was always eager to see the Queens researchers.
The research increased our understanding of how dogs can “see” the world by using their noses. We think that this study significantly enhanced Treo’s capacity to detect a change in emotion at home. The study confirmed for us that dogs are extremely intuitive and sensitive creatures, and that using their best skill — sniffing — has enormous value.
The research findings have been published in PLOS ONE. Clara Wilson, a PhD researcher, and Kerry Campbell, an MSc student at the School of Psychology, conducted the study. Catherine Reeve oversaw them, and Zachary Petzel assisted in gathering the human physiological measurements.

Only you and your family can decide what is best for your home, but according to Hafeez, it might not be fair to bring a dog into a house where the owner might not be able to adequately care for the dog’s emotional or physical needs.
According to her, dogs are currently trained to recognize visual cues rather than odors associated with stress and anxiety. A service dog may be able to recognize symptoms of an anxiety attack or increased stress by smelling the person. ”.
“People frequently get dogs for their homes because they only consider how cute and cuddly they are and what the dog can do for them,” she continues. They might not understand that owning a dog, even an adult one, is like having a perpetually dependent toddler living in your home. ”.
“A dog is a living, breathing creature that needs attention, care, grooming, regular vet checkups, and sometimes medication and additional precautions for pre-existing medical conditions,” says Hafeez. In addition to needing food, shelter, and walks.
Additionally, dogs encourage people to exercise, which reduces stress and alleviates loneliness.
We have 12 million smell receptors, to put it into numbers,” he said. “Dogs have at least 50 times that number. ”.
Animal psychologist Clara Wilson, the study’s first author, said that it “provides additional evidence of the extraordinary abilities of’man’s best friend’.”
A therapy cat, Oscar, is thought by some to have sensed death was coming based on a change in how people smelled when they were close to death, Dodman said.
They are aware of the differences, she acknowledged, but do they care? “I assume they do, which is why they are effective emotional therapy animals.” ”.
It’s long been widely believed that dogs can detect extreme emotions by smell. Now scientists at Queens University Belfast in the U.K. have proven that a dogs nose knows.
FAQ
Why does my dog smell bad when stressed?
When a dog is anxious or stressed, the anal gland secretions can release in large quantities all at once, leaving a potent fishy or musky odor in their wake.
Can anxiety make my dog smell?
Additionally, when your dog is afraid, in addition to expressing his glands, dogs occasionally also urinate and defecate, which worsens the odor. Many pet owners are shocked when they pick up their beloved dog from the vet or groomer expecting a freshly cleaned furry friend, only to discover that he stinks.
Why does my dog suddenly smell so bad?
If the dog’s skin is where the odor is coming from, an infection might be to blame. Allergies, as well as parasites, bacteria, or yeasts, may be the cause of skin disease. Additionally, canine food allergies can result in an excess of skin secretions, which significantly intensifies a dog’s normal odor.
Do you smell different under stress your dog knows?
A psychologist at Queen’s University Belfast in Northern Ireland and one of the study’s authors, Clara Wilson, tells Gizmodo’s Ed Cara that “our bodies’ psychological stress response changes the smell of our breath and sweat.” “Dogs can detect this change. ”.
