Dog parvovirus infection requires injection of special serum, antibodies, interferons and other biological agents according to the dog's physical condition. After that, according to the different symptoms of the dog's condition, anti-emetic, hemostatic and gastrointestinal protective agents and other drugs can be used for treatment. Because parvovirus can cause serious gastrointestinal reactions in dogs, dogs need to avoid food and water, and supplement needed nutrients and water through intravenous infusion.
