The only way to JRT proof your garden is to put it behind a fence about 6' high. I make it a very strong point to anyone purchasing/adopting one of my pups or adults is: "If you want a beautiful yard or garden, you may want to choose another breed". I let them see my yard and kennels and tell them, I cannot guarantee that your yards will not look like this, are you ready for this. Does this bother you. Hahahahaa. Good luck, be sure you don't plant onions.
