why is snoop dogg called snoop dogg

Snoop Dogg's stage name comes from his childhood nickname given by his mother because he resembled the cartoon character Snoopy from the Peanuts comic strip. His real name is Calvin Cordozar Broadus Jr., but his mother called him "Snoopy" growing up, which stuck and evolved into "Snoop Doggy Dogg" when he began his rap career. He later shortened it to Snoop Dogg as part of his professional identity.
