KANSAS CITY, Mo. — Commissioners with the Unified Government of Wyandotte County and Kansas City, Kansas, repealed a citywide pit bull ban Thursday.

For nearly 30 years, several breeds — the American Pit Bull Terrier, American Staffordshire Terrier and Staffordshire Bull Terrier as well as mixed-breed dogs with any characteristics of those breeds — have been banned in KC city limits .

That will change after the Board of Commissioners voted 6-3 to repeal the pit bull ban ordinance, which went into effect in 1990.

The repeal takes effect immediately , according to the repeal ordinance.

The Humane Society of Greater Kansas City. which helps assist with KCK’s animal shelter, was among the repeal’s champions.

Most of the breeds in KCK shelters are pit bulls, making them unadoptable in the city.

The Commission passed dangerous dog ordinance in 2014, so the pit bull ban was redundant and unnecessarily punitive to non-aggressive dogs of the breed, supporters said.
