Thanks to Deb for this info!!
Providence has no BSL against Rottweiler, but does for Pit Bulls:
Sec. 4-54. Registration of certain breeds of dogs required.
Any person having the custody, ownership or control of any American pit bull dog, pit bull terrier dog, or Staffordshire terrier dog must register said dog with the city on a form to be provided by the city. Said form shall require the following information: Name, address and telephone number of the dog's owner; the address where said dog is harbored, if different from owner's address; dog's sex, color, Providence County rabies certificate and tag number and other distinguishing physical characteristics of the dog, as well as proof of public liability insurance of not less than twenty-five thousand dollars ($25,000.00) for such registration. The fee for registration shall be twenty dollars ($20.00).
