Perros del Mal Producciones, often referred to as just 'Perros del Mal', was a Mexican professional wrestling promotion founded in October 2007 by Perro Aguayo, Jr. when he left Consejo Mundial de Lucha Libre and became inactive around 2015. The promotion shared a name with Aguayo, Jr.'s wrestling stable (group) Los Perros del Mal and the stable is the main Rudo (villain) group in the promotion. The promotion had an "open door policy" which meant they did not generally have wrestlers under contract but hired them on a per appearance basis. Perros del Mal was also a booking agency, responsible for hiring the core Perros del Mal group and others to various independent promotions all over Mexico.
