Federal authorities and local police agencies today raided two Westside marijuana dispensaries as well as the residence of the owners.

The raids occurred at a facility on Washington Boulevard in Culver City and on Overland Avenue in Los Angeles. Authorities recovered undisclosed items and are continuing their investigation, according to a Drug Enforcement Administration spokesman. The names of the owners whose homes were searched were not immediately available.

During one of the raids, officers shot a dog believed to be a pit bull, but the circumstances of the shooting remain unclear, a law enforcement spokesman said.

The Drug Enforcement Administration, Federal Bureau of Investigation, Internal Revenue Service, Los Angeles County Sheriff's Department, Los Angeles Police Department, Torrance Police Department and Culver City Police Department took part in the raids.

Law enforcement agencies have been cracking down on pot dispensaries for some time, but officials did not immediately say what prompted these raids.

[Update] Officials said they reported 200 plants, 100 pounds of marajuana, $100,000 cash and made one arrest. The dog that was shot by authorities was treated by a vet and expected to make a full recovery.
