Did you know that dogs have a sixth sense? They are better than any humans at reading body language, so they already know when you're going to feed them or take them for a walk, but they have another hidden talent… and it could save your life.
Dogs also have a much better sense of smell than we do. When you live with a dog, they get used to your scent and they can detect changes in your body. You may have heard stories about dogs who detect cancer in their humans, but they aren't just stories – many dogs can naturally pick up on the tiny volatile chemicals given off by cancerous tumors in humans. They can even be taught to alert diabetics of their low blood sugar, allergic reactions and epileptic seizures!
