What's mean Fridu ? 

Fridu is the composition of two Breton worlds "Fri" for "nose" and "Du" for black. Fridu which translates in "BlackNose" is a typical name for a dog, as many Breton's dogs have a black nose, it's quite a common name.

Who's dog is then Fridu ?

Fridu was my daughter's teddy dog. Fridu disappeared more than 10 years ago when she was still a nice little girl. While my daughter has some suspicion on who the criminal could be, nothing has never been proven.
