Kiss your roses good bye. The only plant I have in my backyard is a tree (which one of my dogs climbs). I don't know if roses are harmful for dogs to eat, but my dogs all like to munch grass. We used to have a crate merdle(sp?), but the dogs munched that to a stump. So the backyard is what the dogs make of it. If we want a pretty yard, we have the front.

You could try some kind of chicken wire or fencing around the plants. A garden supply store like Home Depot would be able to show you what to use.
