Denver opened the doggy door to pit bulls on Tuesday night.

Voters in the Colorado city approved a measure to lift a 30-year-ban on the pooches, local outlets reported.

With the measure passing, owners would be required to get a restricted license for their pit bull — limited to two per home — and would need to have their dog microchipped.

They’d have to pay a higher fee than is required for other pups, maintain appropriate paperwork and have no issues for three years before the restricted license would be scraped, according to The Denver Post.

Councilman Chris Herndon led the charge to get the measure on the ballot after Mayor Michael Hancock vetoed the city council’s attempt to repeal the ban earlier this year.
