You rang?

On the subject title...very unclear as to why the Vet wants to with hold water from the dog, yet does a sc injection of water just in case the dog is dehydrated.

Yes adult dogs, especially those not previously vaccinated can come down with Parvo. If previously vaccinated and they still come down with it, then most likely the vaccination was given inappropriately or was damaged in some way to decrease its potency so as to not invoke an immune response. Given that Parvo is endemic in dog populations most dogs are exposed to Parvo at regular intervals throughout their lives.

In adult dogs Parvo is usually not serious unless the immune system is compromised. The virus itself prefers the very rapidly dividing cells of the intestinal lining in puppies. In adult dogs the intestinal lining is not growing and dividing as quickly. Thus the virus does not propagate as fast in adult dogs, resulting in a milder disease.

Of course all of this conversation is assuming it's Parvo, and instead it could be the equivalent of food poisoning resulting in an intestinal bacterial infection.

In either case the chances are with the antibiotics for the bacterial infection or to prevent a secondary infection as a result of Parvo (or Rota, or Reo) virus, along with a bland precription diet, puppy-dog will soon have all 4 paws on the ground again.

Another PT crisis over!
