The character Snoopy is a black and white beagle. Snoopy is one of the characters in the "Peanuts" comic strip created by Charles M. Schultz. He was first introduced as Charlie Brown's dog on October 4, 1950.
For the first 2 years, Snoopy did not speak. In 1952, Schultz began to portray Snoopy's thoughts in "thought balloons." In 1966, Snoopy's best friend, a yellow bird later named Woodstock, started appearing alongside the beagle. Snoopy has several alter egos, including the World War I Flying Ace and Joe Cool. He has also been shown to have several siblings, including Spike, Olaf, Andy, Marbles and Belle.
At the time of Schultz's death in 2000, the Peanuts comic strip was appearing in 2,600 newspapers located in 75 countries and written in 21 languages. The characters also have several holiday cartoon specials, including "A Charlie Brown Christmas."
