Animal Welfare

 

Overview

contentphoto_animalwelfare

Laws governing the treatment of animals in the United States began to emerge, mostly at the state level, in the mid to late 1800’s. New York’s law, passed in 1867 and spearheaded by the state organization of the American Society for the Prevention of Cruelty to Animals (ASPCA), became a template followed by other states into the next century. Even today, most animal cruelty laws are enacted and offenses prosecuted on the state level. The laws, while similar, have many significant differences which necessitate a close reading of the state statute. Read the full overview.
