Sister and Her Sister-Dog

A girl's beloved dog should be as steady and dependable as an older brother, indulging her pride and protecting her innocence;

at the same time, her dog should be less obedient, with a beast's ferocity, keeping her in check when she goes too far.

When her dog licks her, it's not just a sign of affection, but also a warning:

If you don't behave next time, I'll bite you.
