Parvo in 5mo.old schnauzer who's @ vet 3 other dogs starting to show out of character behavior.
(Flat Top wv. USA)
Rocco, got a laceration on right front paw that put him in the hospital for 9 days. I brought him home with 6 staples in laceration. He threw up in car and pooped diarrhea with in 2 min of the 20 min ride home. I carried him in put him on floor and my 8 yr.old pitbull greeted him home and so did my 3 yr.old pitbull then my 2 yr.old chihuahua.
The next morning I took rocco back to vet to find out he contracted parvo... none the less there from the vet. We are on day 6 of when it all began and my chihuahua has bloody stool and not eating. Yesterday my 3yr old threw up 3 times. Big dog showing no symptoms other than his typical allergies. 3 days ago I administered the feed store bought 7-in-1 shot. Are they symptomatic from the shot or carrying the virus.
I don't want to take then to the vet's office just in case it's from the shot. But everyday my rocco doesn't improve much. And he is now on the 6th day sick after showing symptoms still with diarrhea and not eating. I want to know his chances on survival also.
I'm so sorry to hear what's happening with your dogs. Unfortunately Canine Parvovirus is VERY contagious and if your older dog's weren't current on their vaccinations then they could very well have caught Parvo from your infected puppy.
All puppies should be fully vaccinated starting at 8 weeks old, and older dogs vaccinated either annually or every 2 or 3 years depending on the particular vaccine used (as some are effective for longer than others), in order to be fully protected.
If you gave them their shot after they were exposed to your puppy who was sick then it wouldn't prevent them from catching the disease, whether it would make it better or worse is impossible for me to say as I'm not a vet but your own vet can give you all the answers you need.
I strongly recommend that you get all your dogs to your vet for diagnosis immediately, Parvo is a killer virus and they will at the very least need fluids and antibiotics. In young, unvaccinated puppies the mortality rate for Parvo is very high, in older pups or dogs who have had vaccinations (even if not the full 3 sets and annual boosters) it may be less severe, but every single dog is different and there's no way to tell for sure.
Please get your dogs veterinary help now so that they have the very best chance of surviving this horrible disease. I wish you lots of luck and really pray that they all come through it. Good luck.
