A golden retriever turned into a doctor when he diagnosed his owner with an illness before she got sick.

Christina Lee, a software engineer from Northern California, taught her dog Cache to talk to her by pressing buttons on a communication device.

The device is pre-programmed with words such as "food," "friend," and "mom." But when Cache pressed a button saying "sick," Lee was initially skeptical as she felt fine. However, five hours later, she began to feel unwell.

"This is the first time that he's predicted when I would get sick ahead of time," says Lee. "I think he could smell it on me or something."
