The Hong Kong pooch with a “low-level” coronavirus infection has reportedly tested negative for the deadly bug.

The ailing pet was placed in quarantine after oral and nasal tests at an animal facility showed traces of the bug in its system on Feb. 26.

On Thursday, the dog showed signs of recovery, when a blood test came back showing “there are currently not measurable amounts of antibodies in the blood,” the Washington Post reported.

Despite the results, Hong Kong authorities still believe the dog could be a carrier of COVID-19, and are keeping the canine in isolation until that possibility is ruled out.

However, medical experts note that some mild infections are not strong enough to produce antibodies that would even appear in test results.

“The repeated earlier test results support this being a true infection,” J. Scott Weese, a professor at the University of Guelph’s Ontario Veterinary College, told the Washington Post. “It wouldn’t be surprising for this to be a low-grade infection because dogs are not thought to be very good hosts for this virus.”

Authorities believe the dog contracted COVID-19 from its owner, but there is “no evidence” pets transmit the virus to humans.
