The ordinance introduced Wednesday would make it illegal for anyone to own a pit bull or a pit bull mix. Owners would have 30 days to get rid of their animals. And violators would face fines of up to $1,000 and up to six months in jail.
The proposal comes almost a year after one woman was killed and another mauled in pit bull attacks in the Dan Ryan Woods in Chicago.
The mayor's office has opposed a breed-specific ban. And an official with the Humane Society of the United States says such an ordinance would be almost impossible for animal-control authorities to enforce.
