Pedro Aguayo Ramírez was a Mexican professional wrestler and promoter who achieved fame in wrestling as Perro Aguayo Jr. or El Hijo del Perro Aguayo ("The Son of Perro Aguayo"). He was the real-life son of lucha libre legend Perro Aguayo and not a storyline "Junior". Aguayo was best known as the leader of the Los Perros del Mal stable, which he started in Consejo Mundial de Lucha Libre (CMLL) in mid-2004. The stable became a significant draw in Mexican professional wrestling, peaking during Aguayo's storyline rivalries with Místico and Héctor Garza. In October 2008, Aguayo left CMLL to start his own independent professional wrestling promotion Perros del Mal Producciones, built around members of his Los Perros del Mal stable. In June 2010, Aguayo returned to AAA after a seven-year absence to start an invasion storyline involving his stable.
While performing in a wrestling match on March 20, 2015, Aguayo died almost instantly from cardiac arrest after fracturing three vertebrae. Following his death, Aguayo was inducted into the AAA Hall of Fame and the Wrestling Observer Newsletter Hall of Fame.
