American Bulldog registration is not required, many breeders produced and sell puppies without registration.  Rosebull Kennels registers our dogs in order to keep track of their pedigrees.  We give our puppy buyers a copy of the registration certificates and pedigrees.  The registration certificate will be very handy if your pup is ever lost or stolen.  American Bulldogs are not recognised by the Canadian Kennel Club thus CKC papers are not available for your puppy.  City bylaws require you to register your american bulldog and get a license.
