I did some research after I posted my question. One of the sites I went to had a short news video here:
Study claims sleeping with pets in bed might be dangerous - KDVR
My adult daughter mentioned today that they don't have their dog sleeping with them anymore because of dangers to humans and what she had heard. This wasn't the first time I had heard this, so I decided to post the question.
The information was not alarming stuff nor anything that would make me want to kick Copper out of the bed at night. I just wondered if there was something I was missing here or is the media hyping yet another story?
