The very first time I used it my dog was sitting outside and a giant brown snake slid up right near her, bumped into the mesh, turned around and went away. It happened so fast neither me or the dog knew what was happening. It happened the morning I was leaving and I tell you what, I put the dog in the van and packed up quicker than I ever have before, even with the new fence. It really does pack up so fast! But I'm so glad I went with the Inflatafence, any other fence would have let the snake through and I'm not sure my dog would still be alive. So thank you for saving my girl :)
