Parvovirus is a virus that causes canine coronavirus disease in dogs. If your dog has been infected with parvovirus before, he is more likely to be infected again now. If your dog eats contaminated food or water, this can cause them to become infected with parvovirus.
If the dog lives in a harsh environment, this may cause them to be infected with the parvovirus. Therefore, if you want to prevent your dog from getting parvovirus, it is recommended to take your dog to the veterinarian regularly to ensure that it is properly diagnosed and treated.
