The Humane Society of the United States is the nation’s most effective animal protection organization. With you by our side, we take on the big fights to end suffering for all animals.  Our work complements the work of local groups and animal rescue leagues by focusing on national-level issues like ending the puppy mill industry, strengthening cruelty laws and eliminating large-scale animal abuses. We also run programs and spearhead campaigns designed to ease the burden on local sheltering groups.
