The video above shows just one of the group's trips down the hill; Douglas says the kids and dog did it several times, and they all got along (though that one little girl's foot nudge to Diana was almost time-out worthy). Still, when Douglas saw what was going on, it put a smile on her face — and not just hers.
"Everyone [at the restaurant] was delighted and impressed," Douglas told The Dodo, adding that the kids love it, too (of course).
Diana's owner, Vania Lucia, has been raising the dog and her siblings since they were born to a stray. She told The Dodo that Diana learned the trick from her daughter, who loves to slide down the hill as well. Since then, it's become her favorite pastime.
