In 2004, the Colorado State legislature passed a statute increasing the penalties and liability for dog attacks and prohibiting any legislation based on breed. This law effectively repealed all pit bull breed bans in Colorado. There are appeals in process contesting this ruling, but at this time, breed ban legislation is legal in Colorado for cities that have home rule charters. Many apartment complexes restrict certain dog breeds due to their insurance liability coverage. If you’re renting, please check with your landlord for current policies.
