That's actually harder to answer than you might guess. The short answer is that once a bike is going fast enough several forces tend to keep it upright. My guess is that somebody gives the dog a running start and somebody else is at the ready to catch him. Which forces are at work while he's rolling is the hard part of the answer. It's not just gyroscopic forces, it's not just the trail effect, and it's not any other single force. Research published as recently as 2011 says that it's a combination of forces. It's fascinating to me that something so simple can be such a big mystery. So much so that I felt like jibber jabbering about it here.
