Snoopy is a beagle, a breed of dog known for being smart, playful, and affectionate. Although some people may not think Snoopy looks like a beagle, he is a perfect portrayal of the standard breed. Snoopy is a spotted white beagle with a rich fantasy life, and he became one of the most iconic and beloved characters in the Peanuts comic strip. His creator, Charles M. Schulz, based Snoopy on an actual pet dog he had when he was thirteen, which was also a beagle. While there are other dogs that look like Snoopy, such as Bayley, a Mini Sheepadoodle, Snoopy himself is a beagle.
