'm so pleased to see so many positive posts about dogs. The reason we started caravanning was so we could take our Westies on holiday with us, after all they are part of the family!
In answer to the first post, if you drill a small hole through the windbreak pole near the top, you can use cable ties threaded through the material and the holes in the poles, to hold up the material. The cable ties can be cut off after each use and only cost pence. There is always a danger of the fabric tearing but if that happens, then perhaps a windbreak isn't the right thing to be using to restrain your dogs.
