Our new neighbors behind us have a couple of ankle biter dogs that will always come to the pvc vinyl fence and aggressively bark and bounce off the fence. Our last neighbor had the same type of dogs but one of our dogs decided she had her fill and pushed one of panels through and grabbed their dog. It was a short lived attack because I was able to bust my fat ass out there and tackle our dog before she could cause any damage to their dog, that i can confirm. After that, I decided to train ours not to attack the fence. Now, our dogs can not go out back without the neighbors dogs barking and jumping on the fence. Our dogs never pay anymore attention to it, but it is annoying to listen to all the commotion. So, I sit outside and bark back at them. The neighbors have taken notice and now call their ankle biters back inside.
