The Complete Pluto1930-1947
Pluto is one of the more unique characters in the Disney shorts. While the other characters may also be animals like ducks and mice, they basically act like humans. They speak in English, they own homes and they even enlist in the army from time to time. Pluto is just a dog. He can't speak, he lives in a dog house and his only goal in life is to accumulate as many bones as possible. Since he can't speak, Pluto is a character for which animation is vitally important. The animators have to do their very best to make sure the audience can tell exactly what Pluto is feeling based solely on his facial expressions and exaggerated movements. It's animation at its purest and most basic level.
