If your dog plays outside and likes to dig up your garden beds as much as it likes to chase sticks or catch Frisbees, pet expert Marc Morrone has two tips for discouraging this behavior.
First, lay some wire mesh just under the surface of the soil so the dog learns that it's unable to dig too deeply. Because animals are creatures of habit, once they discover that the area doesn't afford them a good opportunity to dig, they'll look elsewhere to satisfy their urges.
Alternately, you can train your dog to dig in another area by creating a special digging spot and burying some treats in the soil. Once the dog discovers the buried treasures, it will be more likely to return to that spot.
