But it is a time-limited reaction. I believe this is a different scenario from what you are worried about with Archie, which is instead that you are afraid the vaccination triggered a long-term abnormality in his immune system.
It is true that this can sometimes happen, and I realize you are probably doubly worried because you don't want Gus to develop problems later on after his vaccination, too. So I am not discounting your worry in any way. But I think your vet is correct that there is really no way to know whether the vaccination is the true source of Archie's current problems. I know there are websites that link vaccinations to virtually any medical problem a dog could ever experience. And since all dogs in the U.S. are theoretically required to be vaccinated against rabies, based on some of those websites, an owner could worry that any medical problem their dog ever develops must surely have been caused by the vaccination.
In Archie's case, it is definitely true that the timing makes the connection seem much more suspicious. But I don't think you will ever be able to determine for certain whether the vaccination is at fault. So I think your vet will be doing the right thing by continuing to search for alternative causes/remedies that may exist. My heart does go out to you when you see these problems in one so young. As I mentioned on your other thread, my own Peg started exhibiting severe seasonal allergies before she was even four months old. Since they only manifest during the winter and she is perfectly fine in the summer, we know they are not food-related or medication-related. And my other dog, Luna, had extended episodes of diarrhea on-and-off during her first nine months, no matter what food we had her on. Fortunately, that finally straightened out for her all by itself (although we did find at one time she had worms which we had to eradicate) and now she seems to have an iron stomach! So even though Archie's allergies may be more of a long-term issue, I'm hoping that his GI problems will ultimately resolve -- and hopefully sooner rather than later.
