The only way to get it under control is with a kennel. If the dog isn't with you, it goes into the kennel. Of course this means that you have to spend quality time with her when you are home and also arrange for a good size outdoor kennel for when you are away longer, where the dog may need to go potty. After getting the dog kennel trained, this will be the most normal thing in the world for your dog.
I used to have a beagle we rescued and hosted until we could find her a new home. She also ate everything. We had her in a kennel and it wasn't a problem. This was a great experience - now I know what dog NOT to get.
