Indie
From Super-wiki
Indie is a Cavalier King Charles spaniel, owned by Genevieve. At Salute to Supernatural Chicago 2011 in Jared's Meet and Greet, "Indie is always nervous and looks like it wants to have a heart attack. That’s a running joke for whoever sees the dog. It’s scared of everything."
Indy features in both the gag reel and the mockumentary on the Season 9 DVD and Blu-ray
