Wildhog

After you make the concoction and the Wildhog awakes it will follow you around until it is either killed or it's time is up. If it notices a shady or evil character it will tell in tongue that only you and it know and then at your command, will drag the evildoer to you with it's wolf-like teeth. They are also known for being extremely large. When it is killed or it's 800 hours are up, it explodes and dissolves into a pool of Dragon blood.
