As humankind's faithful animal sidekick for tens of thousands of years, always on hand to offer a barrage licks and nuzzles at a moments notice, it's fair to say that our dogs really do love nothing more than to please us. But as generous as our caring canines are in doling out their affections, it turns out they're really none too pleased when we give a bit of ourselves to something other than them.
Most pet owners probably have noticed their furry friends acting a little put off when another pup is getting all their attention, but now rigorous scientific scrutiny has finally shown there is merit to those suspicions. Yes, dogs are totally the jealous type.
Up until recently, it was believe that that least becoming of emotions was experienced by humans alone, but according to a new study from the University Of California, San Diego, that's not the case.
In a series of experiments based on one originally designed to test whether babies get jealous (and they do), researchers videotaped how 36 dogs reacted when their respective owners were instructed to ignore them and instead dote their sweet attention on other objects: a stuffed-animal dog that moved and barked, a jack o'lantern or a book.
