Dogs get jealous.
It's something dog owners have known all along, but now researchers are confirming it.
Researchers went to three dozen homes and had the dogs’ owners to show affection to a robotic stuffed dog, which could bark and wag its tail - while ignore their dog.
The dog owners were also asked to show affection to a plastic jack-o-lantern.
And, read aloud from a children's book.
78 percent of the dogs displayed pushing and touching in response to the fake dog.
42 percent of the dogs also did it when owners hugged the jack-o-lantern
22 percent of the dogs tried to get their owners attention while they read the book.
