Authorities said Tuesday that 70-year-old Oscar Wilcox apparently shot the cow but dropped his weapon during the attack.
His wife heard his screams, drove to the area and hit the cow several times with the truck. Then, she picked up the pistol loaded with "ratshot" and shot the cow a couple of times in the face.
The woman, who was not identified in the police report, told authorities the cow had always been nasty and had attacked her about a week earlier.
Wilcox was treated at a local hospital. The cow was contained in the pasture.
