Police said a five-year-old female hound from a North Carolina family killed a wild fox that wandered into their property late on Thursday, police said.
Police said the fox had encountered the dog in block 120 on Hoyles Creek Road in Dallas, Gaston County, and was not a family guard.
The NC Public Health Laboratory in Raleigh on Saturday confirmed the remains of the fox were rabies-positive, according to a statement from the Gaston County Police Department.
The gray-and-white American pit-bull combination was updated, police said, as she had rabies vaccinated on demand and had been vaccinated against rabies, police said.
Gaston County Animal Care and Enforcement staff informed residents of the Hoyles Creek Road area of the case and verified rabies vaccination for their pets.
The fox is the fourth confirmed case of rabies in the year in the county.
