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!!
Kendall and Kylie Jenner have lost their chihuahua Dolce!
He apparently went missing when they were staying with some friends.
"We still can't find him. We've had him for like 10 years.
He was staying with our friends for a little while. They've been friends for a long time and they really loved him… and then he got out."
They've been using the twitter hashtag #helpfinddolce to try and spread the word.
This is so sad.
We really hope they find him!
