Well all my puppies were about 3,5 months old when we got them from the kennel and always dewormed and with the first shots but I remember once I found a puppy on the street who was about 1 month old or so and we gave him dry food softened with water** to eat or milk** from the vet (I don't know what exactly). You need to let it sleep a lot and I am pretty sure she will need at least the first shots done.
We rehomed that puppy in a good family at 1,5 months old ... so I will contact them to ask if there is anything you should know and write you back.
First thing to do is contact your vet ask him any questions you have even if it sounds silly and ask him his phone number to call him at any time (better if you have his cellphone, home, office numbers). Don't be afraid to ask him silly questions...is not a bad thing to do...he will be a "bad" vet if he don't answer.
(I have 13 dogs and I still ask silly questions

)
**I am just telling you what I remember so you better contact your vet before!!
