DALLAS, N.C. (AP) — A 1-year-old pit bull and a rabid fox got into a tussle that ended up killing the fox after the animal appeared on the dog’s owners’ property in North Carolina.

The incident happened Thursday in Dallas, a town about 25 miles (40 kilometers) west of Charlotte, news outlets reported.

State health officials confirmed two days later that the fox’s remains tested positive for rabies, the Gaston County Police Department in a news release.

The pit bull was up to date on her vaccinations for rabies, police said. She also received a rabies booster shot.

The fox is the fourth confirmed rabies case in Gaston County this year.
