Why are animals being tested when many people can’t get tested?
section_content: Animals are only being tested in very rare circumstances. Routine testing of
animals is not recommended at this time, and any tests done on animals are
done on a case by case basis. For example, if the pet of a COVID-19 patient
has a new, concerning illness with symptoms similar to those of COVID-19, the
animal’s veterinarian might consult with public health and animal health
officials to determine if testing is needed.

What animals can get COVID-19?
section_content: We don’t know for sure which animals can be infected with the virus that
causes COVID-19. CDC is aware of a small number of pets, including dogs and
cats, reported to be infected with the virus that causes COVID-19, mostly
after close contact with people with COVID-19. A tiger at a zoo in New York
has also tested positive for the virus.
Recent research shows that ferrets, cats, and golden Syrian hamsters can be
experimentally infected with the virus and can spread the infection to other
animals of the same species in laboratory settings. Pigs, chickens, and ducks
did not become infected or spread the infection based on results from these
studies. Data from one study suggested dogs are not as likely to become
infected with the virus as cats and ferrets. These findings were based on a
small number of animals, and do not show whether animals can spread infection
to people.
At this time, there is no evidence that animals play a significant role in
spreading the virus that causes COVID-19. Based on the limited information
available to date, the risk of animals spreading COVID-19 to people is
considered to be low. Further studies are needed to understand if and how
different animals could be affected by the virus that causes COVID-19 and the
role animals may play in the spread of COVID-19.

Reviewer feedback on this answer:
Provides information that lets you infer animals get tested because they might be able to get infected.
This information does not answer the question. This answer provides known information on the spread of Covid-19 among animals and whether or not animals can spread Covid-19 virus to people. It does not provide any information on why animals are being tested for Covid-19 as asked in the question.
