Everyone knows the smart black-and-white dog that sits on top of a red doghouse with his best friend---a bird called Woodstock.
Created by the American cartoonist Charles Schulz in 1950, the clever dog is loved by generations of kids and adults. He speaks more than 20 languages and appears daily in 26,000 newspapers around the world.
When Snoopy first appeared, he was not different form other pet dogs. But two years later, he had begun to speak with simple words and sounds. By 1957 he could walk on two legs and was going to school with his master, Charlie Brown, who failed in just about everything. Later he learned to use the typewriter.
Snoopy has done lots of jobs. He has been a bow-tie wearing lawyer, a tennis player, an Olympic figure skater, a world famous grocery checkout clerk, a pilot and even the first astronaut on the moon.
However, Snoopy has always dreamed of being a famous writer. The
beginning of his story is always, “It was a dark and stormy night…” Unfortunately for him no one has ever wanted to publish the story.
In love, Snoopy is as much of a failure as Charlie Brown is at baseball. He easily falls in love but always has his heart broken. He eats to forget, but it never works.
Snoopy is an insightful, feel-good and sometimes sad dog. If you think a little about words, you might find them full of life lessons. Among his most famous lines are “To live is to dance, to dance is to live.” And “Yesterday I was a dog. Today I’m a dog. Tomorrow I’ll probably still be a dog. Sigh! There’s so little hope for advancement”.
