Dogs can smell feelings

Dogs have the ability to smell how you are feeling emotionally and can even adopt your emotions as well. A study conducted by University of Naples “Federico II” proved this to be true. They showed human volunteers videos that would make them feel sad, scared, happy, or neutral. Then they collected samples of the odors released by the volunteers and presented it to dogs. Surprisingly, the dogs exposed to the fear and sad smells were more anxious than the dogs who were exposed to happy or neutral smells.
