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!!
Maria Menounos sure does love her doggie!
The Extra host brought her GAWRGEOUS pooch to the set at The Grove, where Mario Lopez had to battle for the top cutie title!
Maria's pup won hands down! LOLz!
