They can sense the slight change in the chemicals in the sick person's body. This means that dogs can sense when their owner is having a migraine, heart attack, cancer, seizure, narcolepsy, or low blood sugar.
"The dog's sense of smell can detect changes in heart rate, blood pressure, and blood sugar, even though the chemical changes in the body are minute.
There are also many things that a dog can be trained to detect. Based on minute facial expression, body language, and smell, dogs can detect many things. They can even detect the rise or fall of heart rate, which helps them understand what a person is feeling, especially when they are feeling fearful or calm.
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.
A study in a 2018 issue of the journal Learning & Behavior found that dogs respond to human faces that express six basic emotions— anger, fear, happiness, sadness, surprise, and disgust—with changes in their gaze and heart rate.
Previous research has shown that when humans cry, their dogs also feel distress. Now, the new study finds that dogs not only feel distress when they see that their owners are sad but will also try to do something to help. The findings were published today (July 24) in the journal Learning and Behavior.
On this note, research shows that dogs can sense depression, and many of them even respond lovingly to their humans in an attempt to cheer them up. In the same way that we pay attention to their behavior, dogs also pay attention to our actions to determine our “energy” that day.
As Dr. Burch explains, “Considering that dogs can detect cancer, diabetes, and seizures, we have every reason to believe that our dogs know when we are sick. Illness results in chemical changes in the body and changes in hormones and these changes can be detected by the dog's extraordinary sense of smell.”
While the invasive sniffing can be embarrassing, especially if your dog does it to a visitor, it's their way of saying hello and learning about someone. A dog's nose is a powerful tool. Dogs have up to 300 million scent sensors in their noses, compared to humans who only have 6 million.
Pups really do know when their humans are having a rough time, and they use a rich variety of signals to figure it out. Not only can your pet tell when you have the sniffles, but domestic dogs have shown an aptitude for detecting both much more minute mood fluctuations and far more serious physical conditions.
Heartbeats are a reassuring sound for humans and pooches alike, so it may be a comforting gesture for our dogs to be able to hear our heartbeats. It just means that they love us a lot!
Heartbeats can be a very calming noise during times of stress, so it may just be that dogs turn to us for comfort, and listen to our heartbeats to help calm and soothe them. Some more clues that your dog's ears are on your heartbeat are: Cuddling Up To Your Chest Or Belly If You'Re Expecting. Ears Forward And Eyes ...
How Do Cardiac Alert Dogs Detect Changes in the Heart Rate or the Blood Flow? Cardiac dogs are likely to use their strong sense of smell to recognize chemical alterations that occur when the blood pressure or the heart rate changes.
In some cases, dogs have been known to sense when a seizure is about to happen. Heart attacks: It's unclear whether the dog is reacting to a change in odor or behavior, but there are many reports of dogs becoming agitated and barking at the early signs of a heart attack.
Symptoms of Heart Attack in Dogs
Slight fever (over 103° Fahrenheit/39.4° Celsius) Vomiting. Panting/abnormal breathing. Increased heart rate (over 100 beats per minute for large breeds) (over 140 beats per minute for small breeds)
The field got a huge boost in 2004, when a UK charity called Medical Detection Dogs reported that the animals could sniff out bladder cancer in people's urine2. Since then, researchers have been looking at how dogs could be used to diagnose other cancers as well as diseases such as diabetes, malaria and COVID-19.
Many dogs like to sneeze when they play with other dogs or humans. This “play sneezing” is normal and something dogs use to show that they are excited and having a good time. Dogs will also use play sneezing to show that their behavior is only playful.
If your dog follows you everywhere then it's a sign that they trust and love you and that you make them feel safe. Following you very closely can be a sign that they're bored, they want something, they're feeling scared or are just being nosy.

Because of their incredible sense of smell, dogs can detect subtle changes in human scent caused by disease. They can smell out illnesses such as cancer. It turns out that cancer and other diseases or infections have a smell. Chemicals called volatile organic compounds are produced by cancer cells.
According to Animal Behaviorists, 'dogs don't understand human kisses the same way that humans do. ' When kissing a young puppy, you may not notice any signs of recognition at all because they have yet to associate kisses with affection.
Since dogs consider their owners a part of their family and pack, they want to lay on top of them to show them that and to provide them with comfort and security as well as receive it in the process. Laying close to their owner is also their way of protecting what they love, even if there is no real threat or danger.
Dogs absolutely can see TV, and many seem to enjoy it. There are a number of features about television shows that dogs find attractive. Some of these are visual, such as motion, while others relate to the sounds coming from the TV. Dog eyes are very different from human eyes, so they see things on TV differently.
Research at the University of Lincoln, UK, found that dogs, “can recognize emotions in humans by combining information from different senses.”[1] Your dog recognizes when you're sad or in pain by facial recognition and body language, but the most interesting sense they use is smell.
Now a study has found that dogs can do something just as remarkable: sniff out stress in people. The dogs were able to smell changes in human breath and sweat, and — with high accuracy — identify chemical odors people emit when feeling stressed.
