I first saw them at the breeder's when I picked up Molly. She had them in her house with the puppies inside like an exercise pen. When I got home, I realized it was a fantastic way to have mobile fencing whenever, wherever and however I wanted it. So I called her to find out where she got it, and I ordered one set.

Well, needless to say I eventually ended up with three entire sets, and I cannot tell you how much they have helped us. We had some work done to our decking last summer, so we just used the Pet Yard plastic fencing panels to re-route the Cairns to another area. It confines them well even as adults.

Since they grew up with it, they became accustomed to it as a boundary. Therefore, they do not try to escape nor do they realize it's just a temporary barrier. It's easy to snap panels together to make the fencing as large as I want, and when I'm not using it or want to take it to my sister's (my dog sitter when I'm away), I can fold it up and snap a handle on it to carry it.
