Many
studies have been focused on determining if yawning between humans and dogs are
contagious. Results showed that yawning was indeed contagious between humans
and dogs, even with those they are unfamiliar with. In these situations,
yawning was interpreted by animal behaviorists as a form of empathy or social
connection with their humans. There were no indications of stress, anxiety, or
even confusion. There are also studies that show stress yawns being contagious
among dogs. One indicator of stress in dogs is a rise in the levels of cortisol
in the saliva. Dogs that were found to have higher salivary cortisol levels
yawned more often than dogs with normal levels of cortisol. Suffice to say, a
dog’s yawn doesn’t always signify boredom or exhaustion.
