It sounds like you know more about blockages than I do. I know they can be expensive and very dangerous, but have never had a dog go though surgery.
I probably would not give the dog a bed it can chew up, she sounds like it isn't safe for her, and I would crate/kennel her safely (no toys) when I couldn't supervise.
One of the puppies I sold, was eating his toys and got blocked, and they had surgery done on him. I keep toys away from his sister too, as she will tear them up with a vengence, and I expect she would eat them as well. Doesn't eat food, but will eat dog toys.
Anyhow, keep us posted, and let us know what the regular vet says.
