Can pets read human emotions?

I wholeheartedly believe my dog can sense our emotions. We've had a bad cold go through our house the past week. We noticed our dog will lay next to whoever is feeling the worst at the time. Last night it was my 19 year old daughter. She was sitting in the recliner next to me telling me how terribly sick she felt. Next thing we knew, he jumped up and sat in the chair next to her. He looked at her and licked her face, then snuggled down with her under her blanket. It not only looked sweet, but he made her feel so much better.
