History []
The dog was originally owned by Beatrice's family as shown in the intro. After the family was turned into blue birds, they soon left their home and consequently their dog as well.
In The Old Grist Mill, the dog was first seen in the intro with a girl dressed in blue, whom is later revealed to be Beatrice in the final episode. The dog had then arrived back to Beatrice's house and watermill which was being inhabited by the Woodsman, lured by the candy Greg constantly dropped in order to make a candy trail back into the forest. When the dog arrived, Wirt and Greg had mistaken it for the beast the Woodsman had told them of and fled. They found temporary safety upon the roof of the mill, but the dog caught up with them. As a last resort, Greg took the last piece of candy stuck to Wirt's cloak and tossed it into the river. The dog leapt after it only to get caught in the waterwheel, destroying the mill in the process. After coughing up a black turtle it had swallowed, the dog is revealed to be a normal animal.
The Woodsman lamented over his mill and reveals that the dog was not the Beast at all. Greg attempts to befriend the animal but he sets off and isn't seen until the end of the series where he has returned to Beatrice's home and family.
