High Quality Content by WIKIPEDIA articles! In the comic strip, Peanuts by Charles M. Schulz, Snoopy was often stated to have seven siblings. Five appeared at various times in the strip: four brothers, Andy, Marbles, Olaf, and Spike; and one sister, Belle. The two others were never mentioned by name in the comic strip. According to the TV special Snoopy's Reunion, their names are Molly and Rover; however, their appearance is not considered canonical in the comic strip.In the June 6, 1959 comic strip, following the birth of Charlie Brown's sister Sally, Snoopy remarks that he has no brothers or sisters, and is an "only dog." This was later retconned to him being born in a litter of eight puppies. However, in a March 18, 1971 strip, Snoopy writes in his autobiography: "I was born one bright Spring morning at the Daisy Hill Puppy Farm. I was one of eight puppies." Their mother is called Missy, but has appeared only once in Peanuts, on July 26, 1996.
