What is the name of the boys' dog? 

Mike Brady (Robert Reed), a widowed architect with three sons—Greg (Barry Williams), Peter (Christopher Knight), and Bobby (Mike Lookinland)—marries Carol Martin (Florence Henderson), who herself has three daughters: Marcia (Maureen McCormick), Jan (Eve Plumb), and Cindy (Susan Olsen). Carol and her daughters take the Brady surname. Included in the blended family are Mike's live-in housekeeper, Alice Nelson (Ann B. Davis), and the boys' dog, Tiger. (In the pilot episode, the girls also have a pet: a cat named Fluffy. Fluffy never appears in any other episodes.) The setting is a large two-story house designed by Mike, located in a Los Angeles suburb.[4] The show never addressed what happened to Carol's first husband.[5]
The name of the boys' dog is Tiger.
