The Humane Society of the United States (HSUS) does not operate, control, or fund local humane societies. It does provide support through grants, training of animal care personnel, standards of care, and evaluation services. The HSUS frequently works with shelters in disaster operations and large-scale animal rescues, assisting in the evaluation, triage, handling, transport and care of rescued animals. The HSUS maintains the animalsheltering.com website for animal care professionals, and publishes a bi-monthly magazine, "Animal Sheltering" to which 12,300 shelters and rescue groups subscribe.
