We love dogs and cats! Simply put, we work to ensure that dogs and cats (and a few other animals) are placed in loving homes with families who are excited to experience the joy of living with a pet. The Humane Society for Southwest Washington is a nonprofit organization working in Vancouver, Washington, and Clark County. HSSW is an open admission shelter, serving Clark County and the City of Vancouver and residents. HSSW offers an array of pet services, pet owner services and community services.
