YES, you can have a dog that has parvo that has no vomiting and diarrhea. Texas is a HIGH parvo state and dogs should not be allowed outside for any reason until they have had 3 sets of shots. I have taken care of many parvo dogs in the past. Some have made it while others have not. Since your other dog had 3 sets of shots she would not have gotten it since her body already built up the immunity to it.

The shots can cause a reaction which is seen more these days then in years past. I never had a dog have a reaction to vaccines until recently. His blood sugar may have been a little low prior to the trip to the vet and the stress of the car ride and the shots at the vet could have dropped it lower. Then he got the shots and if he did have a reaction then that would cause it to drop even more. He already had parvo and was just undetected by you or the vet so the drop in the blood sugar and his body already trying to fight off the parvo just took its toll on him. Little dogs crash so hard and so fast that they don't always show the "classic" signs as would a larger dog.

The treatment for parvo just treats the problems that can happen as a result of having parvo. It does NOT treat parvo itself. That has to run its course and the dog has to build up an immune to it. The key is to keep the dog hydrated, antibiotics to fight off infections and nutrients to keep the dogs body going so it can continue to fight the parvo. In personal experience, I have them give the dog B12 also and that seems to make a huge difference. The treatment can take up to 5 days and there will be many bad days that it just does not seem like they are improving. I have had one that showed signs of improvement and the next day passed away. It is very hard on dogs.

With him staying at the vet's office then his chances are good. They can monitor him more closely and adjust treatment as needed. Also with him eating then that is a great sign and hopefully will make a full recovery in no time.

Sending Prayers your way.
