I have a 5 month old Dachshund and today she just started her cycle. I was scheduled to have her fixed in like 3 days but due to her starting I have to wait 6 weeks. It's far to cold for this little girl to be left outside for 2-3 weeks while she is bleeding but the diapers we bought come off within seconds of her wearing them. We have tried premature, newborn and the size up from newborn and none of them will stay on, no matter how tight or loose we set them. They just fall right off. Any suggestions on what to do to about this situation?
