Coronavirus in dogs does not require fasting. Coronavirus in dogs is an infectious disease and sick dogs need to be isolated to avoid infecting other dogs. Coronavirus often causes gastrointestinal symptoms in dogs, and although dogs can eat, prolonged diarrhea and vomiting can cause physical damage and require symptomatic treatment at an animal hospital. Dogs infected with coronavirus do not generally heal themselves, as they will vomit and have diarrhea, causing dehydration and electrolyte disorders, which can lead to death in severe cases. Especially in puppies, the mortality rate is higher than that of adult dogs after infection. If vomiting and diarrhea are severe, prompt treatment is necessary.
