10 Sep 2020 Update--
Texas (TX): A domestic dog from a known positive COVID-19 household was confirmed positive for SARS-CoV-2 at the National Veterinary Services Laboratories based upon molecular testing (PCR and sequencing). The affected dog first exhibited a nasal discharge but has since reportedly recovered.
Texas (TX): A domestic cat from a known positive COVID-19 household was confirmed positive for SARS-CoV-2 at the National Veterinary Services Laboratories based upon molecular testing (PCR and sequencing). The affected cat showed no clinical signs and continues to be asymptomatic. Eight other cats and two dogs residing in the same household have remained asymptomatic and tested negative for SARS-CoV-2 by PCR.
