The Rastreador Brasileiro (in English, Brazilian Tracker) is a large breed of dog from Brazil, first recognised by the Fédération Cynologique Internationale in 1967, but an outbreak of disease, compounded by an overdose of insecticide, wiped out the breed's entire breeding stock. The FCI and the Brazilian Kennel Club (Confederação Brasileira de Cinofilia) then declared the breed extinct in 1973 and delisted it. Since then, efforts have been made to re-create the breed. The Rastreador Brasileiro is a hunting dog of the scenthound type. The breed is also known by the names Urrador (for its hunting cry) or Urrador Americano, in reference to the American (U. S. ) coonhounds in its background.
