Protecting shrubs from dogs
You may want to try a combination of tactics: First, spray the area thoroughly with a hose to dilute the scent, which will attract other dogs. Then temporarily put up a barrier – such as chicken wire – so the dog can’t get close to the shrub. You may want to try spraying a product sold to repel cats and dogs (be sure to respray it after every rain). If grass at the base of the boxwood was damaged, dig it up and replant.
