The symptoms of coronavirus in dogs are very similar to those of parvovirus. In the early stages of infection, there are no obvious symptoms and there will be a slight loss of appetite. In the middle stage of the disease, the dog will frequently vomit and have diarrhea. The diarrhea may be accompanied by bloody stools and a foul smell, and the dog will also begin to anorexia. In the later stages of the disease, dogs will develop symptoms of dehydration due to vomiting, and begin to become lethargic and in a poor mental state.

Treatment of dog coronavirus:

1. Use antibiotics, such as gentamicin. After a dog is infected with coronavirus, antibiotics should be used to control inflammation and prevent secondary infections.

2. Intravenous injection of glucose. Dogs suffering from coronavirus will lose their appetite. The disease will continue to consume the protein reserves in the dog's body. It is necessary to replenish it with more energy so that it can fight the disease.

3. Give dogs some antiviral drugs, such as interferon, serum, etc., which can effectively fight the virus.
