First Aired: July 11, 2001

Plot: Peter wins a paid vacation at work, and the family gets ready to go on a cruise. Joe Swanson recognizes the strength of Brian’s nose and offers him a job as a police dog to look for drugs. Brian proves instrumental in finding drugs at the airport and busting a midget gang’s drug ring. When they nail the guy with the drugs Brian Griffin sniffs some and gets a thin white line on his nose of cocaine.

But when Brian gets addicted to cocaine and goes to rehab, Lois insists the family has to cancel the vacation to help Brian. Peter, however, joins Brian at the rehab center and causes chaos and distress.

After leaving the center, Brian stuns the family when he announces that he is leaving Quahog, setting the stage for the next episode, “Brian Does Hollywood.”
