According to new research, canines really love seeing their owners when they are separated.
A new Japanese study suggests that dogs can cry when they reunite with their owners following a long separation. This is according to a recent research published in Current Biology by Japanese researchers. Humans tend to be more concerned about dogs who are crying, which suggests that humans care more. “emotion-elicited tears”Play an important part in interspecies bonds and “can facilitate human-dog emotional connections,”According to the study.
Based on 20 observations and the Schirmer tear tests on dogs, the study examines the behaviors of these canines. According to the study, canines showed more emotion when their owners were present after five to seven hours separation. However, they did not react the same way when they saw other people.
According to the research, canine tear production may be linked with oxytocin. Oxytocin is a key hormone that helps in human reproduction as well as social bonding. Applying a solution containing oxytocin to the dogs’ eyes increased tear production in a similar way as when they were reunited with their owners.
“In this study, we demonstrated that dogs secrete tears when reuniting with their owner, and our data suggests that this tear secretion is mediated by oxytocin. This is the first report on positive emotion stimulating tear secretion in a non-human animal, and oxytocin functioning in tear secretion,”The study is available here.
Unmatched by any other animal “dogs have evolved or have been domesticated through communication with humans and have gained high-level communication abilities with humans using eye contact,”According to the researchers, Therefore, canine tears “might play a role in eliciting protective behavior or nurturing behavior from their owners” in a way that’s similar to the bonding between humans and their own children.
Participants in the study showed a better attitude towards dogs who were weeping than those with dry eyes. Some dogs were subject to artificial tears, and the participants saw pictures.
“Human participants rated their impressions on photos of dogs with or without artificial tears and they assigned more positive scores to the photos with artificial tears. These results suggest that emotion-elicited tears can facilitate human–dog emotional connections,”According to the study.
