Do you have short fences and a dog who can jump? Have you had any luck teaching them not to leap fences after they've already had success? Have you come up with any techniques to discourage them from doing it? I'm wondering if there's something that can be draped over the fence that would thwart jumpers.

A couple times a month, my neighbor's Scottie has been hopping their short chain-link fence to harass us on our leashed walk to the park past their home. Until yesterday, it was just annoying. My three would get excited, but the Scottie would keep its distance. The neighbor kids dutifully alerted their parents, and the problem was abated.

But yesterday, the Scottie's housemate, a larger, more athletic white dog, learned the trick. First came the Scottie, then the white dog -- both leaping the short corner of the fence. Much to my dismay, the white dog wasn't as shy as the Scottie. It charged right up to my dogs to investigate with a demeanor that didn't look playful.

With three leashes in my hand, the only thing left for me to do was to stick my foot out to stop the impending assault. I did so, and the white dog looked none too happy at that. I was a little afraid he was going to charge again -- this time at me.

Fortunately, he backed off and I was able to make my way home while the neighbor kids were running to get help.

As much as I don't want to go through it again, I can sympathize with my neighbors. They're renting, and there's not a good solution to the fencing problem. They have closed off a smaller section of the back, but the dogs often follow the kids to the front where there's more room to stretch their legs.

But the fact that both dogs leaped, with some trouble, the low corner of the fence makes me think there's something that could be put over the fence to solve the problem in low-tech fashion. Since it's occurring at a corner in the fence, I'm thinking a board could be placed over the corner to make it a tougher jump.

Any other suggestions or similar tales of fence-leaping woes?
