The National Humane Society, Newark, Delaware, is a non-profit dedicated to protecting animals from suffering and improving their lives through compassionate action, education, advocacy and policy change. It stands with shelters and humane societies across the country, helps fund individual shelters, spay and neuter programs and veterinary care for pet owners in need, and works to improve perceptions of adopting animals to help address the over-population of dogs and cats in the US. Its national car sweepstakes help fund this work.
