 During the late 1970s, realizing that this dog was on the verge of extinction, Ralf Bender began to work towards rescuing these dogs.In 1977 he acquired a female and traveled all over the State of Rio Grande do Sul (RS) to gather the last specimens of the breed, and then began to breed them.His work came to fruition in 2001 when CBKC (Brazilian Confederation of Cynophilia) officially granted recognition to the breed and conferred upon it the name Campeiro Bulldog.
