I must disagree. I think it actually more of a modern thing to portray dragons as big, dumb animals. Look at Chinese mythology. Dragons in there are not run of the mill monsters. Jormungand of Norse mythology was the offspring of a god. These were some real meanies, not dumb pushovers.
Even if Jormungand were a Dragon, which it's not, it would be about as representive of Dragons as the Fenrir is of wolves.
As for chinese "Dragons" the mythological basis's of D&D dragon had more in common with a rotweiller than them.
lets look at some examples here:
Greek Dragons are mostly put to sleep and whatever they're guarding taken without a fight.
Fafnir took one sword stab.
Depending on the version Saint Georges Dragon was put down with either a single lance thrust or just by by the sign of the cross.
The Abbington Wyrm was chopped to pieces by a single well equipped knight.
Even Smaug the Super dragon with (excepting extra heads) all abilities of every folkloric Dragon ever and the unique ability of being smart enough to use language, was shot dead with a single arrow.
In Arthurian legends it's treated as a more impressive feat for a knight to slay a lion than a dragon; and they slew many.
If you think D&D Dragons are shorted, feel free. But don't claim folkloric precedent. It's not with you.
