BSL meaning in Governmental ?

Breed-specific legislation (BSL) is a type of law that prohibits or restricts particular breeds or types of dog. 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. 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 and Marine Corps have taken administrative action as well. Due to opposition to such laws, anti-BSL laws have been passed in 21 of the 50 state-level governments in the United States, prohibiting or restricting the ability of jurisdictions within those states to enact or enforce breed-specific legislation.
