A research from Queens's University, UK, indicates that dogs can perceive the stress of their guardians by smell. According to the analysis, the accuracy is 93.7%. Also according to the study, "the smell of stress" is recognized by the sweat and breath of humans.
In total, of the 700 tests performed by the researchers, in more than 650 the dogs identified by sweat and saliva that the person was stressed.
The veterinarian says that dogs have 220 million olfactory receptors compared to the 50 million in humans, which makes them more effective in differentiating and identifying odors.
In some cases, such as the dogs of the Police Battalions, they are used to identify something suspicious. She explains that the dog's snout is so powerful that it can even identify the emotions of its owner and perceive things that go beyond human understanding.
Another study has shown us that dogs not only sniff out our stress, but also feel the effect of it and other emotions such as fear and happiness. Sometimes the animal can be more agitated and stressed if the owner is too. As these animals have a keen sense of smell, we need to pay attention to what we are going to pass on to them for a good relationship," says the expert.
Service dogs that help people with mental health problems, such as anxiety and post-traumatic stress disorder, may benefit from these findings. The research also opens the door to investigate whether dogs can differentiate emotions, in addition to knowing how long the animal can detect smells.
The Veterinarian gives some tips on attitudes that the guardian can have to relieve this load of stress and not transfer these emotions to the pet. "Taking a good bath when you get home to remove the stress sweat or even changing clothes are attitudes that help your puppy not to get stressed, so you can spend more quality time together
