Colleen Mansfield is a snobby, vain, arrogant, wealthy woman from Beverly Hills, California and a participant of the Beverly Hills Dog Show. Colleen, along with her French Poodle, Appoline, participating in other dogs and won three consecutive times. They participated again in the 25th Annual Beverly Hills Dog Show against the Cortez family and their dogs, Delgado, Papi, Chloe, and Pedro for $50,000, and when the finalists go against Appoline and Papi, Colleen makes one of the judges question about his breeding papers and since its against the rules to participate without them, Papi is disqualified thus making Colleen and Appoline winners for the fourth consecutive time by default.
Her pet is a French poodle, Appoline, until the latter was set up for adoption given Mansfield's demise.
Colleen became one of the victims of the Anti-Hunters.
