In law, breed-specific legislation (BSL) is a type of law that prohibits or restricts particular breeds or types of dog.^[1] Such laws range from outright bans on the possession of these dogs, to restrictions and conditions on ownership, and often establishes a legal presumption that such dogs are dangerous or vicious to prevent dog attacks. Some jurisdictions have enacted breed-specific legislation in response to a number of fatalities or maulings involving pit bull–type dogs or other dog breeds commonly used in dog fighting, and some government organizations such as the United States Army^[2][3] and Marine Corps^[4] have taken administrative action as well. Due to opposition to such laws in the United States, anti-BSL laws have been passed in 21 of the 50 state-level governments, prohibiting or restricting the ability of jurisdictions within those states to enact or enforce breed-specific legislation.^[5]
