Y.A Novel? hmm...

I've had this idea in my head for years, maybe 4-5 of them. I told it to a guy I once dated who also was into writing, and he scoffed at my idea but I figured, hell, its not like I have to publish it. I still want to write it though.

What is it you ask? Well I haven't worked everything out... and maybe this idea has been though of or done before, but I wanted to do a story about a dog. A genetically enhanced dog, thrown into some sort of government conspiracy. I'm not sure how well I can pull this idea off, or much less if its something I will stick with, but who knows?
