Endo is one of those just-happy-to-be-here dogs — even when 'here' is the vet's office. On top of that, he's got springs for legs, which is how he wound up in a viral video.

A video of Endo, who gets some pretty good air, was shared by Colorado State University, and got picked up by news outlets like AP, USA TODAY and CBS, where he was dubbed the 'jumping dog oddly excited to see veterinarian.' (CSU vets are just that good.)

But, it looks like Endo jumps like this a lot of places, from the ski slopes to the kitchen, and yeah, even the place typical animals fear most, the vet.

CSU later put a GoPro on Endo... but it's not for the motion sick.
