All the more reason why I should thoroughly check out the breeder and examine the puppy before I buy it.
Just because a puppy could turn out to have some health problems doesn't mean I shouldn't get one. That's like saying that you shouldn't have sex because your baby may turn out to have some sort of genetic problem. I'm sure most people who own a pet understand the risks of getting one, or at least should. That said, I'm sure 9 times out of 10 the puppy will be just fine. If it's not, then of course I'll still take care of it. Though school will be an obstacle, I always have my parents to help me out, one of which is a stay-at-home mom.
The other points have already been addressed a couple of times before, but thank you for giving your advice.
