If you like breeding dragons in DragonVale for the iPhone and iPad, then you’ve probably looked all over for the ‘cancel’ or ‘abort’ button when you realize you bred something you already have or may not want. So is there a cancel or abort function somewhere in DragonVale?
Unfortunately no there isn’t. It’s part of the game that you have to wait it out and see what you get.
You can speed up the process with gems, but you can’t cancel breeding, and I doubt you will be able to in the future either.
