In 1989, Pitbull #1 and Pitbull #2 wrestled briefly in the World Wrestling Federation, losing to The Hart Foundation on March 4, 1989. They also lost to The Brain Busters on June 27, 1989, and the Fabulous Rougeau Brothers on Prime Time Wrestling aired on September 25, 1989.
The Pitbulls debuted in Extreme Championship Wrestling in April 1992, both competing in battle royals to crown the first ECW Heavyweight Champion; neither were successful. Pitbull #2 left shortly after, and Pitbull #1 became known as "the Pitbull" and won the WCW Television Championship on April 16, 1994. Later in 1994, the Pitbulls reunited and had notable feuds with Public Enemy and the Bad Breed. The feud with the Bad Breed culminated at November to Remember in a match where the losing team was forced to split up; the Pitbulls were victorious. The Pitbulls won their first and only ECW Tag Team Championship on September 16, 1995 at Gangstas Paradise from Raven and Stevie Ric
hards. They were soon joined by Francine, who became their manager and dubbed herself "The Beastmaster". One month later, they lost the titles back to Raven and Richards. In 1996, The Pitbulls moved into an intense feud with The Eliminators, which saw their manager Francine receive the Total Elimination on two occasions. The feud culminated at the first-ever CyberSlam in a three-on-three dog collar match, which saw Francine team with the Pitbulls against Stevie Richards with The Eliminators. The Pitbulls won the match after superbombing Richards and letting Francine pin Richards. However, The Eliminators hit the Total Elimination on Pitbull #1, Pitbull #2, and Francine after the match. After this, Pitbull #2 went on to win the ECW Television Championship on June 1 at the Fight the Power event; he held the belt for only twenty-one days before losing it to Chris Jericho at Hardcore Heaven.
On July 13, 1996 at Heat Wave, Francine turned on The Pitbulls and became the manager of Shane Douglas. The feud between Douglas and The Pitbulls culminated on April 13, 1997 at the first ECW pay-per-view Barely Legal, where Pitbull #2 faced Douglas for the Television Championship in a losing effort.
The team lost to the Headbangers on WWF Shotgun Saturday Night on August 24, 1998.
On March 4, 2000, they returned to ECW as they lost to Roadkill and Danny Doring.
