Sen Dog was born Senen Reyes on November 20, 1965 in Cuba. He would soon be moved to Los Angeles, California. While he was all too familiar with gang activity, Sen Dog mainly steered clear of it keeping busy playing football, where he was an All City football player. He also had a ken interest in music.

B-Real and Sen Dog met DJ Muggs through mutual friend DJ Julio G. At the time, Muggs was new to the LA area, having just recently moved from Queens, NY where he grew up around hip-hop culture which he later used in LA to become a popular DJ on the KDAY am hip-hop station. DJ Muggs, Sen Dog, and Mellow Man Ace all tried to convince B-Real to give up gang banging and selling drugs to start a rap group, but B-Real would have none of it, convinced he was making money the easy way. That all came to an end when B-Real was shot in the back, and the bullet pierced his lung. Sen Dog and DJ Muggs were among the people who visited him in the hospital. Once he was better, Sen and Muggs were able to get him to join the group.

Cypress Hill formed in 1986, when Sen Dog and his brother Mellow Man Ace started a group with B-Real and DJ Muggs. Back then, they were known as DVX and they began their own type of music, using Latin and Hip-Hop slang. In 1988, Mellow Man Ace left the group, and they renamed themselves Cypress Hill, which was a local street in LA that Sen Dog once lived on. The group would be based on the everyday experiences of life on Cypress Avenue. With this formula, they created a new type of hip-hop, often mixing Latin music with Mexican-American street culture. They continued to play local shows until they were signed to Ruffhouse/Columbia records in 1991.

In 1991, "Cypress Hill" was recorded and released, and it quickly went double platinum. On the "Check Your Head Tour" with the Beastie Boys, Cypress Hill met Eric Bobo. Cypress Hill's first smash hit "Insane in the Brian" made them an instant MTV sensation, and they were a big hit among hard rock and hardcore rap fans alike, making them one of the first highly successfull rap/rock bands.

In 1994, Eric Bobo had become a full member of Cypress Hill, and recorded the album III (Temple of Boom) with the group. In 1995 the album was released, and it went almost immediately platinum, but all the pressures were too much, and Sen Dog left the group.

Sen felt he wasn't getting to do his own thing enough, so he started his own rock group, SX-10.

In 1997, Sen Dog returned to the group for the album "IV", and all chemistry returned and Cypress Hill also released "Skull and Bones" which spurred the smash hits "Rock Superstar" and "Rap Superstar" which further blurred the lines between rap and rock for this pioneering band.

Currently, Sen Dog is playing shows here and there with SX-10, while they prepare their next studio album.
