BIRMINGHAM, Ala. (WIAT) — Dogs are known as our best friends, and apparently, they don’t want you to forget it!
A new study says canines can feel jealousy too. Researchers at the University of California San Diego had owners play with a toy dog, a book, and a plastic jack-o’-lantern, all while ignoring their pets.
Some of the dogs got aggressive, pushing their owners while they played with the fake dog.
And most of the pets tried to sniff the bottom of the toy dog, suggesting they thought it was real.
Researchers think jealousy may have evolved in dogs because they’ve been domesticated for so long.
