Avis Blakeslee says she was attacked as she tended to her petunias outside her Stroudsburg farmhouse.
She says she pushed the animal to the ground after it bit her on Monday. She then held its jaws shut with one arm as she flagged down a passing driver with the other.
Blakeslee's teenage grandson, who lives next door, heard the motorist's cries. He ran to help, followed by Blakeslee's son, who shot the animal.
A state wildlife official confirmed the fox was rabid.
Blakeslee ended up spending four days in the hospital.
