Madd Dogg was born and raised in Los Santos. Madd Dogg started rapping at a young age and got his big break when he performed at the Los Santos Forum in 1988

Jimmy Silverman witnessed the performance and signed Madd Dogg to Blastin' Fools Records. Alan Crawford, Madd Dogg’s childhood friend became his manager and they both began working on his debut album.

Madd Dogg first gained extreme popularity as a rapper, without any full albums, in the late 1980s. He quickly earned enough money to buy his mansion, pictured on his first two albums.

In 1991, he released 24 Carat Dogg and also a hit song ‘A Dogg’s Bitch’, a duet with his girlfriend Rochell'le. It appeared on her album Leg$.
Madd Dogg is still extremely popular, even having merchandise such as a clothing label Madd Tagg

Madd Dogg begins to sink into depression after his rhyme book went missing and his manager was killed (both of which were done by Carl Johnson, ironically his future manager, in attempts to jump-start rival OG Loc’s music career).

Outside of these attacks, he also struggled with “alcoholism and egomania” (as told by Lianne Forget), drug abuse, massive financial debt, as well as breakups with Rochell'le and his rap group “Doggy Boyz”.

Later that year, he was forced to give his mansion to a Vagos drug lord, and was supposed to give a concert in Las Venturas before he went missing. When Carl Johnson discovers him, he had a room at the Royale Casino, and after he had gotten drunk and gambled away his fortune, threatens suicide before CJ saved him and sent him to rehab. Madd Dogg then hires CJ as his new manager, unaware that CJ ruined his career in the first place and rescued him out of remorse.
As his manager, CJ begins by taking back his mansion and directing Madd Dogg to record a new album. CJ also takes back the original rhyme book from OG Loc, and recruits his friends Ken Rosenberg to work as an accountant for Madd Dogg, and Kent Paul as his sound engineer. At the end of the game,

possibly in early 1993, Forty Dogg is released and quickly achieves gold record status.
In 1994, he released “the less-than-stellar” N.L.A.D.B. (Never Leave a Dog Behind), which would become his last album in the 3D Universe and direct him to retire [citation/verification needed]. Since his retirement, he has focused more on ghostwriting and producing for other artists. As of 1998
