These forst vaccines in these young pups don't do anything. Most likely they have killed their mother's antibodies as long as the pups were nursing. Anyways, since she is so very young I would put the crate close to the driver's seat so she doesn't feel lonely. Discard my earlier ideas as I didn't have a clue how old she was. Right now you are establishing trust so take it easy with her. With these wicked smart pups it is easy to forget how young they actually are. I have to remind myself this quite often. Yesterday he saw a news anchor's full face on TV and jumped backwards and barking. Normally I would have stressed about it but instead I remained calm, told him, "it's OK" petted him and he was fine.
