Dragon Pokemon are weak against themselves actually (DRAGON type), but they are also weak against ICE types. ICE works very well against Dragonite since it is a FLYING type as well which means you get a 4x damage bonus, the same goes for Aerodactyl even though it is a ROCK/FLYING Pokemon. Hope this helps :)
Dragon's Den or the Safari Zone.
any dragon type
