Roger Leadbeater was stabbed to death while walking his springer spaniel Max in an area of parkland in the south-east of the south Yorkshire city on Wednesday evening, local police said.
Emma Borowy, of Fearnhead Close in Bolton, was charged with murder. She has been remanded in custody to appear before Sheffield Magistrate's Court on Saturday. "Roger was a 74-year-old man out walking his beloved dog, Max, when his life was taken in the most brutal and cruel way. Even as Roger lay fatally injured, Max never left his side.
"Roger doted on his family and was a good, hard working and decent man. Even at 74, he still worked for Sheffield City Council, driving children to school with special needs.
