After ECW's closure, Begnaud was signed by World Wrestling Entertainment and was assigned to their developmental territory Ohio Valley Wrestling. While in OVW, Begnaud formed a tag team with Shelton Benjamin called The Dogg Pound. Together, The Dogg Pound won their first and only Southern Tag Team Championship on July 17, 2002. Begnaud, under his Redd Dogg ring name, then made his televised WWE debut on the January 16, 2003 episode of "SmackDown!". He was placed alongside John Cena in an enforcer role, replacing Bull Buchanan, who was betrayed by Cena. After only one appearance on the SmackDown! brand, Begnaud was immediately moved over to the Raw brand and was subsequently renamed Rodney Mack. He made his "Raw" debut by attacking D'Lo Brown on an episode of "Sunday Night Heat", with Theodore Long switching his managerial services from Brown to Mack.
