I put it on upside down so it snaps at the top of her but instead of her belly so that you can get the tail through one of the snap holes. I snapped one snap on either side and left the middle one undone for the tail. You can get them for a couple bucks at Walmart or Kmart. Then just have it on her when you can’t watch her. Take it off when you take her outside (if she goes outside and not on her pad). If she goes on a pad just be sure to take it off once in a while so that she can go potty, but watch her when it’s off so you can stop her if she bites or licks the incision.
