Chad, we have now gone to a infalted Inner tube for our LGD. It is light but cumbersome so it discourages jumping over fences and such. One of our LGD is a big hunter of small animals like gofers, moles and unfortunately cats. I woke up one to many times wondering what the hell was outside the bedroom window digging in the flower beds(for moles). He only jumped over at night and would go back to his sheep, but I was getting worried he might get the barn cats and I am rather fond of them.
