The Humane Society of Southern Wisconsin (formerly the Rock County Humane Society) is a private nonprofit 501c3 organization whose mission is to provide shelter and humane care to lost and homeless pets, reunite lost pets with their families, promote positive pet adoptions and educate our community in order to inspire compassion and responsible pet guardianship.
Started in 1910, the Rock County Humane Society (RCHS), as it was named, has been saving the lives of animals in need for more than 100 years. Just like then, the new Humane Society of Southern Wisconsin is an independent community shelter with 35-40% of its annual budget coming in from private donations and fundraising, with the remainder coming from adoption fees, contract services, and inkind gifts that save us in expenses.
In 1959, RCHS secured land to build a shelter and broke ground on our previous site at 222 S. Arch Street, Janesville, in 1962. After many years in our Arch Street building, we were quickly running out of room. In 2017, we decided it was time to make a change and started planning for a new building . We were fortunate to receive a generous estate donation that allowed us to purchase a beautiful 44-acre parcel land located centrally between Janesville and Beloit on County Road G. We broke ground, began building our new facility in 2021 and move in June of 2022. While a lot has changed since 1910, including our building and enhancing services to be broader in care, one thing has remained constant: our commitment to securing safe and loving homes for every adoptable animal and humane treatment for all.
