Hopefully you'll have some time to see how your new baby does in the house before company comes.
Do not put her in a closed room. Let her have accesss to the room with her crate and baby gate the doorway.
If she is loose in the house, absolutely put signs up on each door to the outside for that door to be opened cautiously and closed securely.
Secure any gates outside and post warnings there as well.
Give her plenty of exercise before the company comes.
My Oliver doesn't like my small grandchildren so he is always babygated away from them. Since you may not know much about your new girl, consider every safety precaution.
