Yes, since we live on the corner, we get a lot of traffic of kids walking by the fence. I think there are some who push the pickets off. We have had several pickets removed before and we have replaced them. This one is again a different picket and I don't think a little 10 lb. dog is getting those pickets off. It's getting very frustrating.
Thanks for the info. Im going to put signs up today and check with the animal shelter again.
