Gandalf wants to join a Great Dane loving family. He is two and a half years old and is good with kids, cats, and other dogs. If you’re looking for a Great Dane for your home, Gandalf may be the guy for you. Update: Gandalf’s foster family calls him “Sloppy Joe” because he has a bit of a drooling issue after he has a drink. He’s like a few friends of ours in that way.
