Try separating Izzy from the rest with an xpen or baby gate when you give chews or treats. With chew bones, you could also try sitting with her and holding the chew so that she learns that you are the keeper and you decide when to take it away. At the same, train her to "drop it" and "leave it." I had to do this with Max because he is possessive of Texas Toothpicks and other chew bones.
My other boy Teddy likes to have his bones and chase Max for his, but I don't worry too much because it is more of an enjoyable game to them.
