Norbert

From Hpwiki

Norbert is a dragon, a Norwegian Ridgeback. Hagrid illegally won the dragon's egg in a game with a "stranger". He hatched it out in his hut, fed and nursed it, and called it Norbert. Soon, the tiny dragon grew large and dangerous, and Hagrid had to send him away. Harry Potter had the idea of sending him to Ron's brother Charlie in Romania. How they managed to do this is a whole different story...
