Snoopy is a loyal, imaginative, and good-natured beagle who is prone to imagining fantasy lives, including being an author, a college student known as Joe Cool, an attorney, and a World War I flying ace. He is perhaps best known in this last persona, wearing an aviator's helmet and goggles and a scarf while carrying a swagger stick.Snoopy can be selfish, gluttonous, and lazy at times, and occasionally mocks his owner, Charlie Brown. But on the whole, he shows great love, care, and loyalty for his owner (even though he cannot even remember his name and always refers to him as the round-headed kid). In the 1990s comic strips, he is obsessed with cookies, particularly the chocolate-chip variety. This, and other instances in which he indulges in large chocolate-based meals and snacks, indicate that chocolate is not poisonous to Snoopy, the way it is for real dogs.
