I bought some pretty shrubs and perennials for my backyard and my two dogs have run of my fenced yard but they have completely ruined the shrubs and flowers, I've tried fencing the plants but my dogs can jump really, really high and get into the plants. I took the fencing down as it was a lost cause. How can I keep my dogs from ruining my plants? I am looking for some way that does not cost alot of money . Please help if you can! Thanks to all who answer.
