No I wouldn't do that either. Don't force them onto each other. Keep them separated. You will see enough over a few days to let you know what she considers them.

And don't forget, being in the house with a calm cat, a dog may still chase and harm a cat outside dashing about. Or even a cat inside who decides to fly through the room

For now, she is in a state of change, so don't force her to do anything, let her get adjusted to being cared for and loved!
