The answer is that dogs can get COVID-19 – well they can get the virus SARS-CoV-2. Do they get sick with it? Open question. They don’t seem to get sick with it but they have been recorded as getting infected.
Can they infect humans? There is no evidence of dog-to-human transmission and the World Health Organization has said don’t do anything about your dog, don’t get rid of your dog, this is not a major source of infection but they can get infected. Can cats get infected? I sincerely hope so, because I hate cats.
