Bleach for parvo?

Species: Dog
Breed: Teacup Chihuahua
Age: 3-6 months
My great pyrenees mix, which is almost a year was a stray before I got her a little over a week ago, we found out yesterday she is positive for Parvo. I've heard you can give dogs small amounts of bleach in water to prevent your other dogs from getting it and to help kill parvo in your pet. Is that true? Should I mix some bleach in water for my chihuahua to keep her from getting it? She's behind on shots. And she isn't showing signs of Parvo, she's healthy as can be and still herself!

Dr. Marie replied:

Oh goodness, no! You have gotten some information confused here.

Bleach is quite effective at killing parvo in the environment but it is not at all safe to use on a pet or to give to a pet in any way.

If you have had parvo virus in your house, then washing the floors thoroughly with bleach will do a good job at destroying virus particles that may be there.

But, do not put bleach in your dog's water! It will burn her esophagus and stomach and would be quite harmful.

The only way to prevent parvo virus in a dog is to get your dog vaccinated for parvo. However, at this point, once she has already been exposed it really is too late to vaccinate her. So the best thing you can do is keep the chihuahua away from any place where the sick dog has had diarrhea or vomit.

I hope that your dogs do ok!
