I am sorry to have to ask this for free. I have been unemployed for over a year now. Thank you for helping.

PARVO !!!

A friends named Zoey had a dog with Parvo, and had the dog put down 2 days ago.
1. What are the after concerns for Zoey now.
2. Zoey was in contact with an older adult Lab, and is worried. The Lab is showing no symptoms after 4 days now. Is the Lab at risk?
3. Zoey has quarrentined herself in her house and is cleaning with bleach. Should she be in quarrentine, and for how long?
4. I was in contact with Zoey as well, should I be quarrentined as well?

Thank you! This is an extreamely shocking disease!!

Dr. Marie replied:

I'm sorry to hear that your friend's dog died of parvo. It is indeed a nasty virus.

Parvo can last in the environment for up to 2 years. However, in most cases, there can be parvo in the yard (where a puppy has had diarrhea) for up to 6 months. In the house, as long as things are cleaned with bleach there really shouldn't be a concern.

Parvo is spread via the diarrhea and vomit of an infected dog, so be sure to clean anywhere where the dog was sick.

It is unlikely that your friend spread parvo to the adult lab. There would have to be virus on her body and the dog would have to ingest it. So, for example, if she stepped in diarrhea from the puppy and then the lab licked her boots it could be spread.

The parvo vaccine is very effective so if the lab is vaccinated he should be fine. We rarely see adult dogs get parvo.

It sounds like you are Zoey are doing all of the right things.
