The Thin White Line (1)
Taking his therapist’s advice, Brian starts helping others by doing volunteer work. Peter wins a paid vacation at work, and the family prepares for going on a cruise. Noticing that Brian’s nose has great strength, Joe offers him a job as a police dog to search for drugs. Brian becomes a successful drug-sniffing dog for the Quahog police department, but along the way he gets addicted to cocaine. Because of Brian’s cocaine problem, Lois insists on canceling their family vacation in the Bahamas to help support Brian while he’s in rehab. Peter is disappointed that the vacation has been canceled, so he decides to tag along with Brian when he sees the beautiful clinic. A therapist at the clinic tells Brian that Peter is a bad influence on him. Although Brian defends Peter and leaves rehab in protest, Brian thinks that he needs time away from the Griffin family to find himself, and leaves Quahog for parts unknown.
