In late April 2020, the CDC confirmed the first COVID-19 cases among cats in the USA. Two cats in New York tested positive, with at least one presumed to be infected by an owner who had COVID-19. In early June 2020, the first dog in the USA to test positive was a German Shepherd in New York, infected after its owner tested positive. The dog later died, although its concurrent lymphoma leaves questions about the exact cause of death.
