I'd say I'd never be able to watch this now without being disappointed that they weren't all animated dogs, but there's a good chance that I'd have thought that anyway. It's like how I can't watch the 1993 Disney movie without expecting Cardinal Richelieu to strip down to a corset and high heels to perform a song and a dance routine (which is even weirder because it's only that movie I have such an expectation with, not any of the many, many other things Tim Curry has starred in).
