Dogs really do get jealous, scientists say Published: July 24, 2014

Ever feel like your dog was jealous when you played with another pooch, Today asks? It might not have been your imagination, according to a new study.

The object of jealousy: a stuffed dog that barked and wagged its tail. Researchers compared how dogs reacted to their owners petting the faux canine with how they reacted to them showering love on a jack-o-lantern pail and reading a noise-making pop-up book aloud.

Dr. Christine Harris, an emotion researcher at UC San Diego, got the idea for the study after playing with her parents' three border collies.
