Snoopy

Snoopy is most likely derived from the English verb "to snoop," meaning to pry or investigate, rooted in the Dutch snoepen, meaning to eat secretly or pilfer. As a name, it suggests curiosity and a nose for discovery — qualities that make it especially evocative for pets with an investigative streak. The name became globally iconic through Charles Schulz's beloved Peanuts comic strip, first published in 1950.

Snoopy ranks #127 among America's most popular pet names, and it carries perhaps the most beloved legacy of any name on this list. The beagle from Peanuts — dreamer, pilot, friend, and philosopher in his own right — gave this name a depth of cultural meaning that has lasted over seven decades. Naming a pet Snoopy is an act of affection and nostalgia, a nod to one of the most iconic animals in the history of popular culture. It suits any companion with a rich inner life and a talent for napping.
