福克斯新闻 狗狗也会羡慕嫉妒恨?（在线收听）

Fido is so much like you — he gets jealous. They say they know because they put it to the test.

Researchers went to the homes of 36 dogs with three stuffed animals or toys. When the owners embraced what appeared to be another dog, Fido snapped and barked in jealousy. When they weren't growling, Fido was whining.

The research, which was led at UC San Diego, involved 14 breeds including Yorkies, Chihuahuas, Dachshund, Pomeranians and the rest were mixed.

And all pointed to the same thing: dogs are hardwired for jealousy just like people.
