Oh my goodness! My CockerSpaniel ate my cell phone and anything else he could get a hold of. Finally got him to "trade" the not suppose to eat item for a treat. For a piece of carrot or a couple of cherrios (his favorite) I would get my precious item back. He would not let go until I actually said "trade".  He started spending his days hunting for trades and sometimes would come out with a sock or other laundry items to trade. 

Wonder who the smart one really was?
