Parvovirus Causes Temporary Closure of WCHS

Parvovirus Causes Temporary Closure of the Whitman County Humane Society

Pullman, WA  –  January 19, 2021  –  Two litters of puppies received by the Whitman County Humane Society at the beginning of January have tested positive for parvovirus. Parvovirus, or parvo, is a highly contagious, potentially deadly disease that attacks the gastrointestinal tracts of unvaccinated dogs.  It is particularly deadly for puppies, causing vomiting, diarrhea, fever, and lethargy.  The virus spreads through contact with contaminated dogs, environments, or people.

The shelter has been coordinating treatment of the infected puppies with WSU’s Veterinary Teaching Hospital and with TLC Animal Care and is following protocols for isolation and decontamination efforts.  Until the puppies are cleared by the veterinarians, and the site has been fully decontaminated, both the shelter and the dog park will remain closed to the public out of an abundance of caution. 

The shelter will reopen once the puppies are cleared by the veterinarians and it is safe to resume services.  As always, any animal adopted from the Whitman County Humane Society has received all age-appropriate vaccinations, including for parvo.
