You have a puppy that is too young to leave her litter mates. You are already at a disadvantage because you have to make up for a crucial three weeks that she missed out on. On top of that, do not cripple yourself by refusing to crate train. Look up threads on bite inhibition training, how to socialize, how to keep the puppy safe because she is too young to be out and about with no shots, how to potty train, how to teach her to self soothe, and so on. Crate training is not cruel. You are doing a disservice to your puppy by not opening your mind to tried and true training techniques. Read about the breed, spend time on the forum, and read about how to raise a healthy happy pup.
Good luck to you
