Dogs get jealous, too, even of hidden rivals
April 16, 2021 – Of course, your shit loves you and you love them. But do dogs also show some negative side effects of deep love, such as jealousy?
Research published in Psychological Science he says yes. Researchers have found that dogs will come to show jealousy, even if the owners only imagine that they are interacting with a potential opponent.
The investigators placed 18 dogs in situations where their friend interacted with a fake dog or a woolen cylinder. The cylinder served as a control, the fake dog as an enemy.
The dogs were seen placing the fake dog next to the owner. Then a fence was put up to prevent the real dog from seeing the fake dog.
The dogs were tied tightly by the owner when the owner appeared to be stroking the fake dog behind the fence. The dogs pulled with much less force when the owners stroked the polar cylinder.
“The research supports what many dog owners firmly believe – dogs show jealous behavior when their friend interacts with a potential opponent,” said Amalia Bastos in the New Zealand paper at the University of Auckland, where she was the lead author of the paper.
In previous studies, 80% of dog owners said their pets would show jealous behavior, such as barking and tying a leash when caring for other dogs, the study said.
According to new research, dogs are one of the few species that show jealous behavior, just as humans can have when a child gives love to another child.
“In humans, jealousy is closely linked to self-awareness, which is why animal knowledge researchers are interested in studying animal jealousy and other secondary emotions,” the research said.
Bartos said it is too early to conclude that dogs are as jealous as humans, but “it is clear that they react to situations that cause jealousy, even if these are out of sight.”
A 2014 study at the University of California, San Diego found that puppies were disturbed when owners showed love for stuffed dogs designed to bark, groan, and tail in a convincing manner.
This jealous line only surfaced when the owners approached the stuffed dog and not when they were busy with random objects.
