Regulations for owning a pitbull in baltimore county maryland?

In 2007, the Breed Specific Legislation (BSL) tried to pass a law that would make people keep pit bulls muzzled when in public and in cages when at home. Luckily for pit bulls, Animal rights activists fought this and the law was not passed. For now there are no regulation in Baltimore County as a whole. Hopefully it will stay that way because it is unfair to overgeneralize dog bites like that. When we're not alowwed to persecute people in America, who knew we would begin persecuting man's best friend?
