I actually did not buy this to protect my yard from deer.  We do not have any deer anywhere near my house.  I got it to keep my very large and enthusiastic rottweiler from digging up the plants, that we just planted in the flower bed.  Apparently,  she thinks it is her digging box.  So far so good.  I'm hoping that when the flowers are mature plants and a bit larger, that she will give up her quest to remove them.  If not, we will keep buying more of this deer netting.
