[Harry Potter] In The Sorcerer's Stone, why didn't Malfoy immediately tell a teacher when he saw that Hagrid had a dragon?

Malfoy sees Norbert hatch, but never goes anywhere to get Hagrid in trouble. It seems obvious that he would go to a professor like Snape immediately and get the situation investigated at the very least, but nothing happens until several weeks later when they are trying to get Norbert off of the grounds! Does he not care to get Hagrid in trouble, or is he just trying to get rid of Harry and company instead or something?

Malfoy was 11 years old. He enjoyed being in on a secret and having the power to blackmail people. In his mind, if he went to a teacher, it would be acting like a Hufflepuff, not a Slytherin. 

Also, if he had gone to a teacher, Dumbledore would probably have covered it up for Hagrid.
