It is a good thing for dogs to urinate because of parvovirus, because when dogs are infected with parvovirus, they will become dehydrated due to vomiting and diarrhea, resulting in reduced urination or even no urination. In severe cases, dogs may die from dehydration. But when the dog urinates, it means that the body is starting to metabolize, so it is a good thing. However, urination does not mean that the dog's condition has improved. Treatment still needs to be persisted in order to have hope of recovery.
