I only worked briefly on the film Oliver & Company, before moving to London to animate on Who Framed Roger Rabbit instead. These are a couple of leftover design sheets for Einstein and Dodger.
I remember trying (but failing) to come up with design that wouldn't remind the audience of other Disney dogs. Dodger looks like Tramp's little cousin, and Einstein...well, you know.
I had the chance to do a pass for all characters, including Fagin, who turned out somewhat more original.
I'll post other design doodles from the film once I locate them.
