I'm no expert either, but I got help from a behaviorist one time over a toy hoarding problem. Eddie was attacking other dogs. That's different than a food problem with humans, but maybe the advice I was given will help.

* Increase her exercise. A tired dog is a well-behaved dog.
* Leash her during play time. You may have to do this for weeks before you can try going unleashed. Depends on her reaction.
* Take away the toy (chew toy) when play time is over. You take control of it and decide when she gets it.
* Teach a 'leave it' command.

Ugh, that's about all I remember. But it's all about you being alpha, not her. It's a very serious problem, and you may have to battle if forever. But you can definitely make things better.

Eddie still has an occasional problem and I have to go back to the basics with leashing, toy removal, etc. But I've seen a world of difference.

Good luck.
