We may be moving soon to a home with a chain link or rod iron fence. Is there something I can put on Callie and Finn's collars to keep them from going under until I have made sure there are no holes and escape routes? I was thinking like a large fishing bobber or something that doesn't weigh anything. A small floatie toy or something? Not a wooden spoon. The issue is going "under" not "through" railings. Thanks so much.
