it is abit to soon for a pup to leave mum but saying that i got one of mine at 6 weeks and i had to feed her 5 small meals aday and i gave her a milk suppliment but as said do not give cows milk, i would make her some dry food moistend with puppy milk to get her started then once settled replace with water and yes a bowl of fresh water down at all times, if she is not drinking at all maybe try giveing a bottle of milk for a few days or a syringe so you no she is getting fliuds, puppies can go down hill very quickly so keep a close eye on her, and maybe seek a vets advice.
