Welcome to Yorkie Talk! You're going to love it here
. I brought Sophie home at just shy of 9 weeks and yes, most will say that's early for them to be separated from their mother and siblings due to socialization issues. Sophie didn't experience any issues however as she was already separated, eating on her own and well socialized. She was just over 2lbs at that time. I feed her small breed Eukanuba puppy kibble and their guideline I have followed is;1 to 4 lbs at 6 to 11 weeks they may eat anywhere from 1/3 to 1 cup. I always kept her water & food out and let her eat whenever she was hungry. She is now a happy, healthy 11 month old little girl and weighs 4 lbs. Be sure to keep some puppy Nutrical handy for her in case she stops eating and her sugar level drops. You will know if she becomes lethargic that she needs a boost. Post photos as soon as you can
. As far as the sleeping noise, I'd ask your vet.
