If you haven't seen it, there's a video of a Beagle stealing a baby's toy . . . and the baby starts crying. So the dog feels GUILTY, and covers the baby with other toys.
(Search for "Guilty Dog Apologizes Baby For Stealing Her Toy. It Is Never Too Late For Apologize For Friends." Although, the way the guy edited the video and added stupid music, it seems like he might have been making the dog do it.)
