According to "The Olympian", Wolf Haven International is "one of the top wolf sanctuaries in the country". When the center first opened, it housed 22 wolves. By 1991, it was up to 36 wolves, and in 2006 the compound housed 47 wolves. Approximately 12,000 visitors tour the facility each year. A variety of wolves are kept in residence, including, gray wolves, Mexican gray wolves, and red wolves. There are also some wolfdogs. While wolves generally live 4–9 years in the wild, those at Wolf Haven International have lived to reach 15–19 years of age.
