If a dog has parvovirus, the owner needs to find out why the parvovirus appears and treat it according to the actual situation. Hyperimmune serum or monoclonal antibodies can be used to target the pathogen; broad-spectrum antibacterial drugs can be used to prevent secondary bacterial infection, and drugs containing ethylamine can be used to stop bleeding; at the same time, rehydration can be used to increase the body's resistance.

If the dog suffers from repeated vomiting or diarrhea, infusion treatment is required. The owner should send the dog to the hospital as soon as possible for diagnosis and treatment by a professional doctor to avoid delaying the condition. Usually, owners must vaccinate their dogs and pay attention to their diet and hygiene to prevent their dogs from becoming microscopic.
