In the United States there is no government-run organization that provides oversight or regulation of the various shelters on a national basis. However, many individual states do regulate shelters within their jurisdiction. One of the earliest comprehensive measures was the Georgia Animal Protection Act of 1986. The law was enacted in response to the inhumane treatment of companion animals by a pet store chain in Atlanta. The Act provided for the licensing and regulation of pet shops, stables, kennels, and animal shelters, and established, for the first time, minimum standards of care. The Georgia Department of Agriculture was tasked with licensing animal shelters and enforcing the new law through the Department's newly created Animal Protection Division. An additional provision, added in 1990, was the Humane Euthanasia Act, which was the first state law to mandate intravenous injection of sodium pentothal in place of gas chambers and other less humane methods. The law was further expanded and strengthened with the Animal Protection Act of 2000.
