The video link seems to not work any more so I found some other links that might help
A co-worker sent this to me today. It’s pretty good super slow motion video reference of some dog motion. There is actually lots of this out on different varieties of character, be it humans or animals.
Saw this one on Today’s Big Thing, they always have cool stuff on this site.
I also found a good collection of them on Break.com. Anything from slow motion slaps to sneezes.
