I'm really sorry to hear this and for the loss of your dog. Unfortunately, what you are describing is not specific to any one disease, so I cannot tell you exactly what happened. In order to tell for sure, I would have to get more information about his case, examine the body and send samples for testing. However, considering how soon he died, this indicates that he either had severe organ damage, or a severely altered blood chemistry. This can happen in cases of certain infections and in cases of poisoning. There are also many other preexisting conditions like cancer, heart/vascular disease and parasitism that could also cause their to be a sudden decline in health. I know that didn't fully answer your question, but I hope that helps you to understand what may have happened. For more information, you may consider asking the veterinarian that gave the treatment, or ask another vet doctor in your area to review the case.

Hi there! Thanks for letting us take care of you today! When there is evidence of blood in the vomit, that raises concern for things like a gastrointestinal ulcer, gastrointestinal tumor, severe gastroenteritis, foreign body ingestion, among other possibilities. The fact that he has seemed weak afterwards is likely due to being dehydrated and possibly anemic though of course other things are possible.he should be evaluated by a veterinarian as soon as possible for further assessment and treatment as I am afraid he is becoming weaker. Some tests that are usually run include bloodwork (CBC and chemistry panel +/- coagulation profile) and abdominal ultrasound. Thoracic/cervical radiographs may follow. Further diagnostics will be based on the findings up to that point. Treatment will be based on findings. Keeping my fingers crossed that everything will be fine with Rambo!
