The Campeiro Bulldog (Portuguese: Buldogue campeiro, Portuguese pronunciation: [buwˈdɔɡ kãˈpejɾu]) is a breed of bulldog from Brazil.

The Campeiro Bulldog was traditionally used in Brazil as a catch dog, catching and holding cattle, often in slaughterhouses.

[1] In the 1970s the use of such dogs was banned in Brazilian slaughterhouses and the breed's numbers declined to the point of extinction, this was further exacerbated by the increased popularity of imported dog breeds.

[1] According to the Confederação Brasileira de Cinofilia's breed standard, Campeiro Bulldogs typically stand between 48 and 56 centimetres (19 and 22 in), with dogs standing between 50 and 56 centimetres (20 and 22 in) and bitches between 48 and 54 centimetres (19 and 21 in).

[2] The breed standard states healthy adult dogs typically weigh between 36 and 42 kilograms (79 and 93 lb) and bitches between 31 and 37 kilograms (68 and 82 lb).
