goofy and pluto

while reading a mickey mouse and friends book and explaining to mosey what all the different characters were: mickey's a mouse, donald's a duck, etc, i came to goofy and pluto and realized that i had stumbled on an age-old paradox. goofy and pluto are BOTH DOGS! they're exactly the same, except goofy wears clothes and a hat, talks, walks on his hind legs and has hands. pluto is a regular old dog, and also a pet. what?? does this blow your mind, or is it just me? all these things that i just took at face value when i was a kid. 

anyway. i guess lots of people have thought about this. here and here for example. many theories, so i'm not the only one sitting around thinking about this. :)
