You can have your own tamed dragon by using the commands, but for a short amount of time. This is a very cool glitch. You can ride and control the dragon but when you ask it to attack a creature it will not and just stay still. It stayed around for maybe 10 minutes then disappeared leaving no trace of it behind.
