Rory

Rory is Fred's pet dog of ambiguous breed (probably a collie). The dog is seen in Arthur's Perfect Christmas, and travels with Fred. The dog is definitely on the wild side due to how energetic he is.

He comes over with Fred when Fred stays at the the Read family house on Christmas Eve and Christmas due to his car breaking down. He takes hold of the box containing Arthur's present for his mom, resulting in wild chase with Pal.

Physical appearance
Rory is a large cream-colored dog who wears a gray collar with a silver pendant.
