I only have one dog, but yes she shares. When we have doggie company, I usually feed them in seperate bowls on opposite sides of the room, but what usually happens is Ginger and Sammy (or Domino, or whomever) will eat about 3/4 of whatever they have, then switch bowls. If a visiting dog grabs one of Ginger's toys she will grab her ball to play with. If I give out chew-chews you can be pretty sure that she and the other dog are going to trade chewies at least once before it is gone. There are the rare occasions when she will get sick of trading, and growl after the second or third trade, but for the most part sharing is not a problem for her.
