Astral Admin - Mwahahaha!
Nah, it was a stupid white, not even mature yet 
the backstory to this liddle dragon is that in the unseasonably cold winter it was able to extend its range down into the lowlands, where it was starting to meet a range of interesting food (and avoiding confrontations with frost giants looking for a guard up in the mountains where it had been growing up).
As such, it had never really come across humans, let alone ones that could be a real threat to it... and with its 8 INT and the white dragon description as straight-forward aggressive"...
Not to mention it is a cool death for the dragon! much better than being nickle & dime'd to death by magic missiles.
- I would add that I made one serious mistake in the running of the dragon. I completely forget about its spell resistance (Doh!) which would have eliminated about half of the magical damage it took on average. Still, I had the desired effect - the weakest form of dragon, only as big as a horse, and it nearly totalled the party.
All that and just CR7
