Work with your pet owner, but euthanasia is never wrong.
"If an owner can't afford to treat a canine parvovirus case, I really recommend working with the pet owner," says Justine Lee, DVM, DACVECC, DABT, founder of VETgirl.
"So, I generally say if you know that they can't commit to daily visits to the veterinarian, for even an outpatient protocol, average studies show that they have to be able to go back to the veterinarian at least once a day for 4 days in a row.
If they're not committed to that, I do recommend humane euthanasia. That said, if they're willing to commit to ideally hospitalization for the first day and then outpatient therapy once a day at your veterinairan for 4 days, some of these patients can survive. So again, a 75-80% survival with outpatient. So, work with your pet owner, but euthanasia is never wrong, especially if they have really severe clinical signs or complications."
