Collected privately in an empty hallway while his friends played a horror game in the other room, which he returned to after the interview. I asked them if they knew, “the scary story where a girl gets her hand licked,” or, “the hand lick dog story.”

The informant does not remember when or where she first heard the story, but assumes it was from a long time ago. She is aware of the variations, but her telling is what she considers to be the true one.
“Uh, I know there’s a bunch of variations on it, but the general gist of it that I remember is that there was a girl… who was having a slumber party with a bunch of friends. And they’re like, ‘Ah let’s all go to sleep.’ And they do, and she had a pet dog who slept under her bed. And when she was feeling scared, she’d, like, put her hand down, and the dog would lick her hand, and she’d be like, ‘Cool, my dog.’ And then she’s like – In the middle of the night, she, like, thinks she hears something, or something? So she puts her hand down and the dog licks it and she’s like, ‘Cool! … My DOG.’ And then she wakes up in the morning and all of her friends are dead, and her dog is dead, and the person wrote on the wall, ‘People can lick too,’ or something of equal stupidity. And that’s the version I remember.”
Unlike other tellings of the story, the protagonist is not alone in her home, but at a slumber party, and wakes up to find everyone dead, including her dog. This version does not specify the method in which the intruder killed, or how the bodies were found, but does specify that the dog was “under her bed.” It also is worth noting that the words on the wall read, “People can lick too,” not “Humans.” It also does not specify the dripping noise that wakes up the protagonist that appears in many versions.

An analysis of several versions of this story, as well as some folkloric history, can be read here: https://www.thoughtco.com/humans-can-lick-too-3299487. Additionally, a video portrayal of the same story can be seen here at http://urbanlegendsonline.com/humans-can-lick-too/, in which the girl actively sees her hand being licked by an intruder, and does not see her missing (presumably dead) dog.
