Capital K-9s is a nonprofit organization comprised of area volunteers to assist the Madison Police Department (MPD) in establishing and maintaining a patrol K-9 unit. The organization was formed in 2004 and is operated by a Board of Directors.

Capital K-9s exists solely to fund and support the Madison Police Department’s (MPD) K9 unit. For many years, the Police Department operated without a patrol K9 unit or any patrol K9 capabilities. While a few K9 teams over the years were assigned to the Dane County Narcotics and Gang Task force (DCNGTF), budget limitations precluded the development of a dedicated patrol K9 unit (DCNGTF is funded primarily through asset forfeitures)

Capital K9 was formed by a group of volunteer community members for the express purpose of funding a Madison Police Department patrol K9 unit.  Funds raised by Capital K-9s are used to pay for vehicles, dogs, training, equipment and other items necessary for the K9 unit to function effectively. Virtually all of the costs of the K9 unit (with the exception of officer salaries and vehicle maintenance) are funded by Capital K-9's.

Capital K-9’s raises funds through a variety of strategies events, community appearances, corporate and business donors, as well as individual donors. Since it's inception in 2004, Capital K-9s has transferred over $ 155,000 to MPD in support of the K9 unit.
