Sonia is a real dog. She buries bones behind the waste paper basket, under pillows, between couch cushions, under Fio's leg, or any other strange and wonderful place into which she can nose a piece of saliva-soggy rawhide.
Doggie gets a new bone every day which she promptly hides, then appeals to Fio to find for her. Mommy makes a big fuss over locating the bone, re-gifting it it with all due ceremony, and
Sonia walks off happy, bone hanging from her mouth like a good cigar.
Ah, if only Fiorella's life could be so good.
