I'm afraid the story of the dog doesn't have a happy ending. After all that we've gone through in trying to deal with Zoey's issues, the one thing we couldn't put up with was her jumping the fence. She flew the coop one too many times and so we took her back to the Animal Adoption Foundation (where she was very eager to get back into!) So if anyone wants a nice dog that's housebroken and pretty well behaved, and you have a home with no cats and a tall fence... she's there for the adopting!
By the way, my cats have all breathed a huge sigh of relief and returned to their normal loving selves again, and aren't busy looking around every corner for signs of an attack!
