My rat terrier, Sadie, was throwing up and very weak. i took her to an emergency vet and it turns out she had swallowed something that didn't agree with her. They did lots of tests to rule out anything more serious, and luckily it wasn't anything but an upset tummy. It ended up costing about $400 (with the tests, emergency vet fee, meds they gave her and sent home with me). VPI paid all but about $50. I have the Major Medical Plan and it's very comforting to know that if virtually anything happened to her, I'd be backed up and not have to worry about the financial aspect. Would definitely recommend to other pet owners!
