The media is a joke and can't get their stories straight. Example a New York Post article from today:

First dog to —test positive— for coronavirus has died in Hong Kong . Now pay attention to the body of the body of the article: The pooch, a 17-year-old Pomeranian, passed away Monday after being returned home to its owner following a government quarantine and a —negative test for the virus— , the South China Morning Post reported. https://nypost.com/2020/03/17/first-dog-to-test-positive-for-coronavirus-has-died-in-hong-kong/

Now in the south china morning post: The dog had repeatedly been tested during its quarantine. A total of five tests from its nasal and oral samples all returned “weak positive” results for the virus. https://www.scmp.com/news/hong-kong/health-environment/article/3075650/first-dog-found-coronavi
