We already mentioned that dogs have the incredible ability to sense stress in humans. However, this canine skill is even more impressive and useful than that. Today, we now know that we can train dogs to detect cancer in humans. Hopefully, one day, we will be able to train them to detect more diseases!
Multiple studies have shown this to be true. To do this, dogs simply need to smell a person’s breath. Once they do, they can detect both lung and breast cancer. However, I’m still confused about how they share their findings with human doctors. Perhaps it was the border collie who learned 1,000 words from our previous slide!
