Snoopy appeared on October 4, 1950, two days after the first Peanuts strip. He was one of the four original characters, along with Charlie Brown, Patty, and Shermy. He was called Snoopy for the first time in the November 10 strip.Snoopy Wood Charlie Brown Peanuts Friendship, Snoopy hug, love, white, mammal png 695x771px 11.78KB Sometimes when I get up In the morning, I feel very peculiar. I feel like I’ve just got to bite a cat! I feel like if I don’t bite a cat before sundown, I’ll go crazy! But then I just take a deep breath and forget about it. That’s what is known as real maturity.” — Snoopy In early Peanuts strips, Charlie Brown was not Snoopy's owner (as seen in the February 2, 1951, strip), and it was not made clear who, if anyone, his actual owner was. At various times, it was suggested that he was Patty's [19] or Shermy's [20] dog. 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.") A toy called The Snoopy Snowcone Machine was popular in the '80s and was later recreated in the 2010s by Cra-z-art.

Snoopy plays baseball in the Sunday strip from April 6, 1952. Shortly after this, Schulz would give him thought balloons and the development of his personality began.

Beyond the keyboard and the screen, I’m someone who’s out to enjoy every bit that life has to offer! Why is it not possible for us to get all the individuals In the world together whom we really love and simply want to remain together?” — SnoopySometimes when I get up in the morning, I feel very peculiar.
