by Jealousy was once strictly considered a human emotion, but some people think that dogs feel it too.
A study published in the journal April. Psychological science. He wanted to test how dogs are jealous. First, every dog saw its owner with a fake dog. Next, an obstruction blocked the view of the fake dog while the owner appeared to be petting the dog.
Even when the dog could not see the rival dog, he showed a jealous attitude (trying to reach his owner by force), which showed that he was acting out of jealousy in a hypothetical scenario. Which has never been demonstrated before.
