Despite his history of conflicted loyalties, his constant disrespect for Charlie Brown, and his inability to remember his name (he nay to him as “that round-headed kid”), Snoopy has shown both love and loyalty to his owner. He joins Charlie Brown in walking out of a game of Ha-Ha Herman when Peppermint Patty insults Charlie Brown, unaware that Charlie Brown is within earshot. He also helps Charlie Brown recover his autographed baseball when a bully takes it and challenges Charlie Brown to fight him for it. When Charlie Brown has to stop dedicating himself to making Snoopy happy, Snoopy replies, “Don’t worry about it. I was already happy.” In The Peanuts Movie, Snoopy remains loyal to Charlie Brown, supporting and caring for him throughout the movie.
In early Peanuts strips, Charlie Brown was not Snoopy’s owner (as seen in the February 2, 1951, strip), and it was initially not clear who his actual owner was. The September 29, 1951 strip implied that Snoopy was owned by Shermy. Charlie Brown was first portrayed as being responsible for Snoopy in the strips of November 1 and 3, 1955; it was not until September 1, 1958, that Snoopy was specifically said to be Charlie Brown’s dog. (In the September 20, 1980 strip, Charlie Brown comments that he once told Snoopy to “stay” and “he never went home.”)
