A new study shows that dogs can tell if someone feels happy or stress.

Dogs have a much better sense of smell than people. Dogs have more than 200 million nerves in the nose, but people have only about 50 million. Dogs also have a larger part of the brain which senses smell.

Some studies suggest that dogs know how we feel and when we are sick. We smell differently when we are sick or our emotions change, and dogs can easily recognize the change. Dogs can sense some types of cancer, and they also know if someone has the coronavirus.

Difficult words: nerve (a brain part that helps you sense the world), recognize (to know who someone or what something is), cancer (a disease in which some of the parts of the body start to grow without control).
