Liz said about the song in a 2018 Rolling Stone Article,

“Did you know there’s a dog at the end of it? Her name is Piggy. It’s Casey Rice’s dog, and she was the Australian sheepherding dog. She was just hilarious. Not a pretty dog. And she would always grab hold of stuff and just not let it go, and so at the end of the song, Casey is actually lifting her off of the ground while she’s holding onto a chew toy because she doesn’t want to let go and she’s just going [growls]. It’s really cute. It’s the last thing that you can hear. You can hear her dog tags jangling.”
