These two are good together when they have a joint mission; like sitting at the top of any stairs and watching for intruders. Charles has begone to bark more than Sofie (if you can believe that?) to keep aliens from attacking the homefront. That includes every package, food delivery driver, or occasional friend of the family.
Sofie: Do you see anything there yet, Chuck?
Charles: Hey, Sof, we need to protect Mom from the aliens!! You with me?
