Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
If this were a kid it wouldn't be cute at all!
Border Collies are commonly regareded as the smartest dogs. But even a beagle could figure out what gets Mabel to do this trick.
She gets treats for being a total brat!
