Why spend money to prove something ANY animal owner can tell you from firsthand experience?
Study: Dogs can feel jealous, too
(CNN) -- Sure, Fido is a brown Lab. But inside, he may also be a little green.
New research suggests that dogs can exhibit jealousy, a human emotion usually ascribed to squabbling siblings or the jilted third of a love triangle.
A study by scholars at the University of California, San Diego found that dogs showed jealous behaviors when their owners displayed affection toward an animatronic stuffed dog that barked, whined and wagged its tail. The dogs snapped at and pushed against the stuffed dog and tried to get between it and the human.
This may come as no surprise to any owner of multiple pooches who has seen them jostle for space on someone's lap. And it's not unusual for people to assign human feelings to their dogs, whose baleful eyes seem like deep pools of emotion when compared with those of, say, cats.
