Do Animals Get Jealous?

You're petting your dog, everything's calm, and the second you reach over to scratch the other dog instead, the first one is back in two seconds flat — shoving its head under your hand, wedging its whole body between you and the other one, staring up like you've personally betrayed it. You laugh and call it jealousy. But can a dog actually feel that? Jealousy isn't simple. It's not fear, it's not hunger — it's a tangled, three-way emotion that needs you, a rival, and something it's terrified of losing. For most of history scientists refused to believe animals could have it. Then a 2014 experiment with a fake barking stuffed dog changed the picture, and brain scans of monogamous monkeys, jealous birds, and sulking chimps filled in the rest. The science says your dog probably isn't imagining it — and where this emotion comes from is stranger, and weirdly more touching, than you'd think. Because jealousy only exists where a bond exists. That pushy little animal isn't being petty. In the only language it has, it's telling you that you matter more than almost anything in its world.
