KANSAS CITY, KS (KCTV) -- Pit bulls have been banned in Kansas City, Kansas. for nearly 30 years. Monday, a group will be going before Wyandotte County leaders to try and get the ban lifted. The last time a group tried to appeal this ordinance was in 2014, however, the vote ended up a tied 4-4 margin which was not enough to overturn the ban.
