Like Dr. Cheng said, take the dog to your vet, have a titre done so you'll know your new dog is well protected against the parvo. At the same time, ask your vet what it means for a dog to be a carrier, the dangers if any, etc. It's better to speak directly to your vet than to read bits and pieces online.
he is for sure 100% vaccinated for parvo, all my other dogs are too.. but i hear even if vaccinated they can possibly still get parvo?? thats why I am SOOOOO worried about this guy being a carrier.. my vet said there are no such things as carriers ( if they didnt have parvo) but online it says differently.. thats why i am soooooo confused! i still have him in isolation and feel so bad.. but i was thinking of waiting 2 weeks and just making sure?? i just dont know what to do?
I routinely perform parvo and distemper titers. If it eases your mind than please have the titers performed.
A vet can do a blood test (titre) and see if they're well protected. I get the impression from what I've read that if a dog has parvo, even as a carrier, and is showing symptoms such as diarrhea, the disease can still be spread through the feces.
All your dogs should be well vaccinated against parvo and then you'll have no worries.
Can you test an adult to see if they are a 'carrier'?
Ireneo has good information for you. Thanks Ireneo!
If your dogs are all vaccinated for parvo than they should be protected.
You can google canine parvo and find many sites that help explain what it is and how it's transmitted. What I found out briefly is: the virus can survive up to 9 months, is not air borne but can be brought in from outside on shoes, paws, etc. In the ground, contaminated feces may be infect others for up to 5 months. Adult dogs can carry the virus with no symptoms. Puppies are most at risk. And areas can be disinfected with a bleach solution of 1 oz of bleach to 1 quart of water. Those are just a few of the facts I found.
