adorable science showing that dogs really do get jealous and how physical activity

affects you differently at work than it does when you're at play. We'll also

Dog owners have long said that their pooch pals get pouty

if they show affection to another dog. Well now scientists have confirmed that they're right.

And you won't believe how jealous dogs can get.

Researchers at the University of Auckland recruited 18 human canine pairs to put their bond to the test.

The dog owners sat in a room next to either a realistic-looking stuffed dog or a fleece-covered cylinder.

so they wouldn't know which object they were interacting with.

Their canine companions released to a door frame across the room.

In the first experiment, scientists had the humans, pets, and praise the fleece-covered cylinder in full view of the dog.

And in the second experiment, researchers showed the dog their owner

sitting next to the realistic-looking dog.

Then they slid a barrier in front of the owners so the dogs
