The Virginia Department of Health will examine a dead fox to see if it had rabies.
That fox attacked a man and his dog in Ferrum.
The fox had bit the man's leg.
He was treated at Carilion Franklin Memorial hospital.
WDBJ7 spoke with the Department of Game and Inland fisheries.
It says foxes are usually shy and travel in the opposite direction of humans.
The fox's behavior indicates it had a health problem.
The Department is urging pet owners to make sure their pets' rabbies vaccination is up to date.
