101719 404 Sioux City Animal Control confirmed they are investigating a dog bite that may have involved a pit bull, according to the Sioux City Journal. The news comes on the heels of the Sioux City Council's 4-1 vote on Monday of moving forward a motion that would repeal a controversial, decades-long ban on pit bulls. Police assisted animal control Wednesday afternoon as they confiscated a dog they believed bit a person in the arm and hand last week. The person was treated at a local hospital.
