If yawn near the dog, she also zevnёt

(«Science-Fact»)

Only a few species have the ability to infect a yawn. Dogs - one such species. If a person yawns next to her dog, she, too, will yawn, with even if you do not see a yawn, but only to hear its sound.
In addition to people and dogs, contagious yawning is also the case with gelada, short-tailed macaques and chimpanzees. It was also observed that people are more likely to yawn, surrounded by friends and acquaintances than alone. This suggests that contagious yawning is associated with a sense of empathy.
Scientists conducted an experiment and found that dogs yawn next to the host 5 times more often than in the presence of strangers. But 12 of the 29 dogs tested yawning with pleasure in the company of any person, even a stranger.
