Wow. A 9 week old puppy is very, VERY young to be brought home. Especially for a Yorkie. The Yorkshire Terrier Club of America dictates that all breeders hold their puppies until at least 12 weeks. It's
imperative that puppies get the proper socialization and training for their mom/litter mates. I know you're excited and I know how hard it is to wait (it was TORTURE for me), but please PLEASE consider asking the breeder to hold off for another 3 weeks. It's only 3 weeks and will make such a huge difference. I'm not trying to upset you or be rude but it is so important that you know these things.
As far as hypoglycemia goes, this will be something you will absolutely have to look out for if you do decide to bring the puppy home. It will be young and I would be so so so weary of leaving it home alone. I am in school too so I obviously understand you don't have any other choice. Make sure she eats small meals 4-5 times a day. Actually, I would free-feed the dog until she gets older. Make sure there is always kibble available and give her some Nutrical before you leave her alone, just so she doesn't go into shock while you're gone. If she does go into shock, she will be lifeless and her gums will be light pink or white. You need to rub Nutrical on her gums and take her to the vet immediately. These puppies, especially YOUNG puppies can fade fast.
Good luck.
