Disinfect clothing, bedding, toys, small rugs and other fabric items that might have been contaminated by running them through the longest wash cycle available on your washing machine.

The general symptoms of parvovirus are lethargy, severe vomiting, loss of appetite and bloody, foul-smelling diarrhea that can lead to life-threatening dehydration. Parvovirus is extremely contagious and can be transmitted by any person, animal or object that comes in contact with an infected dog's feces. Highly resistant, the virus can live in the environment for months, and may survive on inanimate objects such as food bowls, shoes, clothes, carpet and floors. It is common for an unvaccinated dog to contract parvovirus from the streets, especially in urban areas where there are many dogs.
