If the dog does not poop but is just vomiting, it means that the dog's symptoms are still relatively mild at this time. It is recommended to go to the hospital for treatment in time, as the hope of cure is much greater. Otherwise, as the disease progresses, it is not ruled out that dogs will develop severe diarrhea symptoms.

In clinical practice, parvovirus infection in dogs is generally common with digestive tract symptoms, but some also have symptoms of acute myocarditis. The general digestive tract symptoms are: loss of appetite, depression, vomiting, diarrhea, dehydration, and sepsis. In severe cases, blood may appear in the stool.

Another type of myocarditis-type parvovirus often has no symptoms before the attack. Dogs suddenly show symptoms of heart failure: cyanosis of mucous membranes, difficulty breathing, sudden death, etc.
