What is the name of Charlie Brown's pet dog?

Charlie Brown’s pet dog is named Snoopy.

Snoopy is a beagle and one of the central characters in Charles M. Schulz’s Peanuts comic strip. He first appeared on October 4, 1950, just two days after the strip debuted. Although he behaves like a dog, Snoopy has an imaginative inner life and is frequently shown walking upright, using a typewriter, or adopting elaborate alter egos.

A common mix-up is Woodstock, the small yellow bird who becomes Snoopy’s closest friend and sidekick. Woodstock is not Charlie Brown’s pet. Charlie Brown is Snoopy’s owner in the familiar Peanuts setup, though the early strips were less consistent about that relationship; the comic eventually explicitly established Snoopy as Charlie Brown’s dog. Snoopy’s red doghouse, his sleeping pose on its roof, and his fantasies about being the World War I Flying Ace are among the franchise’s most recognizable images.

Snoopy also has a large family of canine siblings, including Spike, Belle, Andy, Olaf, and Marbles, but none of them is Charlie Brown’s pet.
