She's adorable, but please please be very careful with this little one. She is too young, but you've been dealt what you have and now you just gotta do what you gotta do right?

You can do it, but just really inform and prepare yourself.
You'll have to teach her certain things (like bite inhibition) she should have learned from her mama and littermates, which means extra patience in rearing her.
Also you may want to ask around for more specific advise on raising an underage pup. I'm not really too sure if there are any special requirements with her being so young (e.g. with food).
Do NOT take her out of the house or let people track in their shoes. She could catch a parasite or some other nasty thing and go downhill fast being so little. No trips to the petstore for her, no outside, etc. until she is fully vaccinated!
Please just do your research and I know you can be a great mommy! You guys can get through this and do great together!

Welcome to YT you came to the right place for research, questions, and great people!
