I know you want a dog really, really bad. But, you are not ready to have one just yet. I say that because it sounds like no one is going to help you care for it. If it's going to be up to you, spend some time at the animal shelter helping out and learning. They always need walkers and people who will spend time helping socialize puppies.

So, your real first job is talking your parents into providing transportation to the animal shelter so you can volunteer and learn.
