Joalbert is correct. The problem could very well be Parvo virus or other viral enteritis, for which there is no cure only supportive therapy. Antibiotics do not kill virus's. The antibiotics are given for the secondary bacterial infections that may occur. Parvo is very often deadly. I think the use of the IV fluid's were unrelated to the puppies deaths and the timing was just coincidental, unless the IV fluids were contaminated. I have not heard of contamination of IV fluids before, however. You should know once the post mortem is performed.
Condolences for your very sad loss.
PS:How is the mother doing?
That is one of the strangest stories I've ever heard. I have no idea what could have gone wrong with the drip - it makes no sense, but you can't change the facts of the case. Was the original illness ever diagnosed? Please post back and let us know the results of the autopsy. Hopefully what will be learned from your experience will help others.
I hope you get some results from the necropsy soon. Are they doing tissue and blood work as well? It would be nice to find the answers while the last 2 puppies are still hanging in there. Just curious if they used only glucose for the IV's or did they try normal saline or LRS for any of the other puppies? Just trying to narrow it down. And it may not have had anything to do with the IV fluids, just a coincidence. I hope you get answers soon and it would be interesting to know what happened. (I tried to post this earlier but MedHelp must have been working on their site. Couldn't get it to go. Good thing I did a copy/paste)
It sounds that it can be a case of Parvo, specially if theres blood in the vomit and the diarrhea. I work in a Animal Hospital and the other day 2 Pitbulls got Parvovirus, and with that virus one of the symptoms is bloddy diarrhea and vomit.
All the folks that have commented are accurate and this may be caused by seizures.
Seizures can be caused by trauma to the head, metabolic disorders (for example:portosystemic shunt, where blood bypasses the liver, and toxins normally eliminated as waste, travel to the brain, acting as a hallucinogen), and developmental disease such as hydrocephalis. The origin of the seizures can be central, located in the brain; or ideopathic (of unknown origin), or in the body: liver problems, metabolic disorders, etc; or can be secondary to exposure to toxins, or can be a side effect from a medication, a flea and tick preventative, or medicated shampoo as other examples. It is a very difficult problem to sort out.
This kind of behavior can also be caused by eye problems such as retinal deteroriation, other congentital diseases effecting the eye, parasites or toxins effecting the eye and more.
You should video tape some episodes so that you will be able to show your vet the behavior rather just to describe it since your dog may not have an episode during the exam.
A neurological and ophthalmology veterinary exam is important. The most common cause of seizures is ideopathic (of unknown cause). These and most other seizures can be controlled by medications or eliminating the inciting factor (if a toxin or flea and tick preventative, for example). Your dog will need blood tests, MRI, or CT scan, and others tests. Good luck and please keep us updated. Thanks
