I gotta say, Pluto is such a great character, and if I ever got to work with him, I'd be very happy. The scene where he gets caught in fly paper, he's such a great dog!
I've owned a lot of dogs in my life - Marcela, Rusty, Petey Pup, Precious, Rosy and Ava. Each were in love with life's simple pleasures, but being people in dog suits, as they seem to be, they each had a defined personality!
My cartoon strips in college strived to have the Schulzian mix of surrealism and Charlie Brown angst. A bit of that combo shows up in 'Up.'
After my wife and I were married, we obtained a rescue dog from a family that didn't want her anymore. She was a beautiful Collie/Shepherd mix named 'Precious.' It then came to pass that our first marital 'debate' was whether we should change the dog's name away from the same name used by the wacky villain in 'Silence of the Lambs.'
I was a Charles Schulz kind of guy. I didn't read comics books. The Warner Bros. guys were great - Chuck Jones and Friz Freleng.
I've always loved dogs and have had one since I was three. We bought her from a kid selling puppies out of a cardboard box on the street where we lived in New York City. Great dog. We named her 'Marcella' after a Raggedy Ann character. She grew up with us.
