K-9 Hero Haven Inc K9 Hero Haven is a non-profit 501(c)(3) made up by volunteer support, located in Herndon, PA. Our mission is to provide retired working dogs a home for retirement. We also provide non-adoptable dogs with limited opportunities, a place to retire. We take in K9’s from U.S. Customs & Border Protection, K9’s from law enforcement agencies nationwide, as well as Contract Working Dogs (CWD’s), and Military Working Dogs (MWD’s). K9 Hero Haven helps to transition dogs to retirement. If at all possible, we want to re-unite a dog with its handler. We work hard to find good homes for our dogs. We also work to provide dignity and respect to the dogs who need some additional work to prepare them for their journey to retirement.
