I know it sounds funny, but you should be happy that your little Klepto only steals socks and underwear!  Rocky has some odd fascination with KEYS!  We thought it was funny, at first, for him to paw at our pockets or dig in my purse to find them.  That was until my husband was an hour and a half late for work because both of our keys were missing!  We finally found them under the couch, along with a couple  of other stray keys!  And, of course, he barked at us the whole time we were finding his stash!!!  

   At least you can find another sock to put on! LOL!  My husband was very embarassed to go to work and have to explain that the dog "ate his keys"!
