First off I am hoping at this point your puppy is doing much better!! I have worked as a veterinary tech/assistant and now assistant for 8 years and counting. First off I didn't see anywhere in any of the posts where someone might have told you what the vaccination given to your puppy was. From what I can tell without knowing what manufacturer the vaccination came form it seems your puppy was given a canine distemper, adenovirus, corona, parainfluenza, parvovirus vaccination. Honestly I don't know of any puppy vaccinations that don't include parvovirus unless they are bought as separate vaccinations, such as one for parainfluenza, one for corona, etc etc.
To me it doesn't sound like your puppy has parvo. There are several tests available for in house use that can diagnose parvo even if a veterinarian does not think the puppy suffers from that, and we have had a few cases where I work where we have been surprised but even then there is normally a little bit of blood in the diarrhea. Any kind of diarrhea will have a distinct, lovely odor to it and dewormers can often make diarrhea worse, not always but it is possible. At this point if your puppy had parvo you should have SOME blood in the stool, or even stool that looks like it is nothing but blood, the puppy should not be active at all, not wanting to eat or drink, etc etc. Whenever any of my dogs get diarrhea or vomiting, puppy or adult, I will hold off food for a day, let them have water. It allows the stomach/intestines time to rest and they aren't going to hurt missing a meal. If you are already supplementing with nutrical or any kind of glucose in with the water, or pedialyte, you def don't need to worry about not feeding for 24 hours. We don't feed our hospitalized parvo dogs until they stop vomiting for at least 12 hours and often only give them ice chips/small amounts of water while we are standing there until vomiting ceases since they are on IVs. Intestinal parasites/coccidia can make animals feel very poorly or not affect them at all. Coccidia is also tricky to pick up on fecal examinations, even harder to find is giardia. I would lean more towards the possibility of an intestinal parasite issue than parvo, to me parvo would be way way way way on the bottom of my list if there at all. Also keep in mind that the puppy could have some kind of reaction to the medication it is on and it is not totally uncommon for animals to have adverse reactions to sulfa drugs. I am not sure about pyrs but I know dobermans as a breed tend to be more likely to have reactions to sulfa drugs, but also for coccidia there is not really any other reasonably priced treatment other than sulfa drugs.
Also, if an animal has been exposed to parvo before it was vaccinated they can still get parvo. In this case they were most likely incubating the disease when they were vaccinated and at that point the vaccine isn't going to help and you just have to attempt to get through everything. It is also important to realize that keeping vaccines refrigerated is of the upmost importance!! Even when we have puppies who come from a breeder if they vaccinate at home we often vaccinate 3 times (3 weeks apart) as we would normally for an unvaccinated puppy since if vaccines get warm at any point they can and are very likely to become useless. Unfortunately it is not uncommon for vaccines that come from a store like Tractor Supply, Co op, or even those ordered from online pet supply companies to be ineffective because they have gotten warm at one point or another.
Sorry for the long post, if you have any more questions just post here or feel free to PM me, I am sure I have meant to post more here, as long winded as this post was, but just can't think of what else I meant to cover. I hope your puppy is doing much better, I am sure both of you could use a full night's sleep!!!!!!
