Dogs can live through a stroke.

I remember one of my dogs having one and she just sat there and shook and my grandmother held her. She was fine after that though.

She had a few more through a course of a few more years and she was ok till the last one. It made her head tilt, her eyes wobble, and she couldn't walk barely at all.

So in point, if her eyes are wobbly and she can still walk, she should be ok but I would get her checked out asap.
