Have you ever watched very old Olympics footage and thought, "Wow, this sport has progressed so far over the years that it's inconceivable that this performance impressed anybody." I mean, records are records, but you could basically win a figure-skating medal back in the day by skating backward and waving at the same time.
This isn't the case here. If you think the kind of tricks dogs were pulling off in the 1930s couldn't be anything to write home about. Assuming this video is for real, Micky is basically the Michael Jordon of dog jumping. Just look at the mutt fly!
