One City's Experience - The City of Denver
DogsBite.org - The history of the Denver pit bull ban, which was enacted in 1989, revoked in 2004 and reinstated in 2005, is best summarized in a 2005 Municipal Lawyer article titled, "One City's Experience," by Kory A. Nelson, the Senior Assistant City Attorney for the City and County of Denver. A deeper review of the pit bull ban's legal history can be found in, "Denver's Pit Bull Ordinance, A Review of Its History and Judicial Rulings," (download PDF) also by Mr. Nelson.
We gathered the vicious maulings and fatalities that played a role in the enactment of the Denver pit bull ban. Due to the closeness of the City of Aurora, which passed a Fighting Breed ban in 2005, we included attacks from Aurora as well. Though distinctly two separate cities, their histories regarding the pit bull problem overlap. Combined, the Denver-Aurora Metropolitan Statistical Area has an estimated population of 2.3 million, both of which cities prohibit new pit bull terriers.
