Just to clarify, do you mean the Sicilian?
How to beat Dragon Defence
Have you ever heard what Fischer said about the Dragon? He once said he loved to play aginst the Dragon all you had to do was pry open the H file and sac sac mate. Seriously take a look at some of his games against the Dragon

@OP, if you were referencing your last experience against the dragon, you could post it for us to take a look and offer suggestions. The major things that resulted in that loss were developing too slowly, and moving around the same minor several times before you finished with development (i.e. castled your king to safety). The fact that your opponent played a dragon setup was irrelevant.

Occasionally one does beat the common "Dragon Defense." That is why We prefer the Hyper Accelerated Double Dragon Venom Defense and its counter part the Hyper Accelerated Double Dragon Venom Attack with AfterBurners!! :) >:[
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 0-0 8. Qd2 Nc6 9. Bc4 Bd7 10. 0-0-0 Rc8 (10...Rb8!?; 10...Qa5?!) 11. Bb3 Ne5 12. Kb1 is standard theory these days. White prepares for a storm on the K-side with g2-g4 and h2-h4, Be3-h6 and opens up the h-file.
Needless to say, the Yugoslav Attack has been analysed heavily for decades and there is a lot of theory.

However, to play the hyper accelerated yugoslav, you must gambit a pawn to yourself when you capture it with your queen.
I like the closed line to sicilian
