A 46-year-old Fairfield resident was charged July 8 with third-degree assault after a dispute with her sister over feeding a dog from the table in their home.

Angela Lawson, of Hulls Farm Road in the Southport section of town, punched her sister in the arm during the June 27 dispute and she was arrested on a warrant Monday, police said.

She was released on a promise to appear later that day in Bridgeport Superior Court, police said.
