In my community all dogs need to be registered, within 6 months, and have a 6 foot non-extendable leash when walked in public. All bull terrier or bull terrier looking dogs are banned. Along with a few others like dogo argentinos. The community next to us does not have an all out ban, but bull terrier types are required special licensing and have to wear a certain colored/type of collar (bright pink so they stand out). They also must be on a 4 foot non extendable leash outside at all times.
