Dog bowl (Fallout 3)

 is an item in Fallout 3, useful only as Rock-It Launcher ammunition.

There is a rumor however, that there is an easter egg that if you put a dog bowl on the ground, while you have Dogmeat (Fallout 3), Dogmeat (Fallout 3) will go over to it and start eating out of it. This rumor is unlikely to be true, as Dogmeat always follows you and when told to wait, he stands still forever.
