Animal Control Officers, formerly typically called dog-catchers, are found across the USA and are generally employed by local or regional government or outsourced under contract to charities. In the past elected officials were appointed to control things like cattle or pigs but it was deemed illegal to be an elected official in any animal care role and since 2018 all staffing has been filled like any other job. Around the world these tasks are more typically completed by volunteers and charities.
