Residents of Southside subdivision are calling for county authorities to take action after a pitbull attacked a 66-year-old woman and bit off her middle finger at the knuckle.The pitbull is one of many pitbulls owned by a nearby resident who refuses to keep the dogs confined to his property.“I don’t know how I got my hand loose,” said bite victim Terry Carlson, who says the pitbull’s jaw was clamped on her finger for several minutes. “My husband was beating it with a cane trying to get it to let go. The next thing I remember, I was sitting at the kitchen table bleeding.”Carlson said the attack happened inside her home on Wednesday, March 6.
