This could be what is called vestibular syndrome which is not uncommon in older dogs.
You can read about this problem here

It could be due to an inner ear infection or simply something a little off kilter neurologically. It usually resolves on its own.
However you should get her in to see a vet for a full exam and maybe even a geriatric blood work up to make sure its not a sign of something else.
Hope this helps!
