Do Dogs Know When you are Hurt or Ill?
Just as dogs can use our facial expressions as cues when we are happy, they can do the same to tell when their owner is hurt or ill. When you are injured or unwell, it’s likely you will have a different expression compared to your usual everyday face. This change in appearance and possibly your different behavior leads your dog to assume that you are hurt or ill.
Dogs have an excellent sense of smell, and some can even sniff out when a person is unwell. There have been cases where the average pet dog untrained in detecting illness has been able to save their owner’s life by detecting cancer. Studies have shown that dogs are particularly good a detecting lung and breast cancer. It is thought that the change in the patient’s exhaled breath leads the dog to make the link.
A study confirmed average pet dogs could be trained using a three-phase, food reward method could be used to detect lung and breast patients compared to a control group of people.
The five dogs used scent alone to detect the 55 lung cancers and 31 breast cancers in early and late-stage patients. Results showed scent detection compared to biopsy confirmation was 0.99% for lung cancer patients and 0.88 for breast cancer patients.
The International Journal of Gastroenterology and Hepatology reported a study where a Labrador Retriever was able to detect colorectal cancer with 0.91% accuracy and 0.99% accuracy in two sets of exhaled breath samples. The specially trained dog had even better results with stool samples being able to detect early signs of cancer with 0.97% and 0.99% accuracy.
Dogs have also been trained to sniff out cancer-specific volatile organic compounds. Cells in humans change when a heart attack is imminent, and dogs have been known to detect the smell of these changes, making them perfect as an early warning sign.
Dogs’ sense of smell is 10,000 times better than humans, and it is thought that up to one-third of their brain is devoted to their olfactory cells.
Animal-assisted therapy is becoming more widely used in the medical world. Doctors are reporting their patients are happier and healing faster due to the interactions a patient is having with a pet or other animal.
Previous research has shown that dogs also show distress when they hear a stranger cry or a baby cry on a recording, Meyers-Manor said. “I think that they have a general response to this crying, but I think that taking the action to do the rescue may be a little bit more dependent on [the] relationship [with their owners],” she added.
Whats a surefire way to make a bad day a little bit better? Dog owners might say its time spent with humankinds furry best friends. And according to a new study, your pet dog may be happy to help.
And why did dogs with stronger bonds more often open the door when their owners were crying and less often when they were humming? That result may be “reflective of empathy,” the authors wrote.
The researchers found that in that last case, the dogs who had opened the door when they heard their owners crying spent more time gazing at their owners after unsuccessfully trying to retrieve the food than the dogs who didnt open the door. This may suggest that “openers in the distress condition may have a stronger bond with their owner than nonopeners,” and the result is opposite for the task which involved humming, the researchers wrote. In the condition where the owner was humming, the dogs who didnt open the door gazed more at their owners than the dogs who did open the door.
Whats more, the dogs were also able to get through to door to their owners: The door was held shut by three small magnets, so to open it, the dogs just had to lightly touch it, such as with their paws or noses.
The History of Dogs Feeling Our Emotions
Throughout history, there are many amazing stories of dogs making emotional connections to rescue and help people. Dogs have been known to rescue people from very challenging situations. They have sensed danger and been able to save people and at the same time, they add that deeper meaning and sensitivity to the rescue.
They sense the need for emotional support or survival tactics and will find help from other sources. These emotional connections are put to the test in many different circumstances. One very memorable occasion revolves around a dog called Rosella. Rosella was a guide dog for her blind owner, who happened to be working in the tower that fell during the September 9:11 disaster.
Rosella managed to guide her owner to safety during the chaos that occurred that day. She was there giving emotional support to people trapped on stairways who, instead of panicking, were able to stroke a dog like Rosella. It was reported that she made many people, including firefighters, feel calmer in their anxious moments.
Among our canine heroes, there are many reports of snow rescues. It is worth mentioning a Labrador/Border Collie mix called Keno, who was responsible for a live rescue of a lift operator at the Fernie Ski Resort. The man had been buried for twenty minutes before Keno found him beneath the snow, after an avalanche. Keno could sense through an emotional connection that there was still hope for the man. Keno was honored for his bravery and a memorial stands for him at Fernie Ski Resort.
The list of dogs using their emotional skills to search and rescue is extensive. It is very encouraging to read these stories, proving that dogs can feel their owners emotions and the emotions of others too.

Dogs are a commitment. Youll need to get up early every day to walk and feed them, and they cant be left alone for long periods of time — especially when theyre puppies. But its all worth it for the companionship and the unconditional love.
A bunch of recent research has shown the connection between people and dogs goes deeper than us simply being their providers. For example, they might be trying to communicate with us when they do certain gestures like rolling over. One study even suggests they might be making faces at us to look as cute as possible, so we do things for them.
According to a new study, published in the journal Learning & Behavior, dogs want to comfort their owners when theyre upset, and they will overcome barriers to do it.
Previous research has shown how dogs are responsive to the sound of humans crying. But the new study, led by psychology and brain science researcher Emily Sanford, found that dogs who detect their owners emotional distress will rush to do something about it.
The researchers recruited 34 dogs and owners, all of different breeds and abilities, and then separated them. The owners were put behind a clear door that was held shut with magnets. They were asked to hum “Twinkle, Twinkle Little Star” or cry and yell for help.
Dogs didnt open the door more often when their owners cried, but those who did open it did so faster than when their owner hummed.
Stress level measures also showed how dogs who were able to push through the door and “rescue” their owners showed less stress. So they were upset by the crying, but they could still take action. The dogs who didnt open the door were too upset and stressed to do anything — it wasnt that they didnt care.
“Every dog owner has a story about coming home from a long day, sitting down for a cry and the dogs right there, licking their face. In a way, this is the science behind that,” said Sanford in a statement.
“Dogs have been by the side of humans for tens of thousands of years and theyve learned to read our social cues… Dog owners can tell that their dogs sense their feelings. Our findings reinforce that idea, and show that, like Lassie, dogs who know their people are in trouble might spring into action.”
