The back legs need to be snug enough so that she can't get through the holes to the incision. I also put it on backwards so the snaps were on her back and not touching her incision. It also had to be lengthened since she fit in the smallest size except she was too long for it.
Please give pain meds. I know some vets don't give it and those vets make me mad.
Sometimes you can't because of other health issues or if the dog had a c-section and is nursing but it is abdominal surgery.
