track in fecal matter on your shoes and expose your dog to it at home.

Rottweiler, are more subsceptible to contracting this disease.

If the puppy survives, he will make a full recovery. There are no
lasting effects of the illness and he will be fully immune to the
disease thereafter, assuming a healthy immune system.
A full series of vaccinations, with the last shot being scheduled for
after 20 weeks of age is essential. Isolation -- don't let the at-risk
dog be exposed to other dogs or their feces.
If you have an area (house and/or backyard) that has been exposed to a
dog with Parvo, you can clean it up with a 3% bleach solution (3 parts
bleach to 100 parts water).
