I know what you guys are going through. I did have a dog die because of bloat and it was awful. We do not have a 24 hr vet locally, I had to drive her up to Chesapeake, which as an hour in a half away. I had fed her a pigs ear and a couple of hours later she was in throwing up and in terrible pain, plus she was 14 years old and very frail to begin with. They told me she had bloat and that her stomach was twisted and that they were going to have to do surgery right then if she had any chance of survival, I told them no, I had her put down right then. Also the same dog had a bout of pancreatitis and that is horrible, if I hadn't gotten her to the vet when I did she would have died. She was in the hospital for two days.
I'm glad to hear all is doing well with both dogs.
