My Bianca is the same! Everyday I come home and I'll take my shoes off at the front door and next thing ya know she's picked them up in her little mouth and carried them off somewhere. Most time it just seems to be the right shoe (the left ones are always left behind)
And underwear too..but never clean underwear. Ewww. She's a disgusting little girl. LOL I don't know how she snatches it away from the hamper but she does and I'll go out into the other room and find a pair of my underwear just out in the middle of the floor - not always a popular trick at dinner parties .
