Human: What is the best way to keep a dog from digging up the garden? Assistant: 
The best way to keep a dog from digging up your garden is to create an underground barrier by burying chicken wire or hardware cloth at least 6 inches deep around the perimeter of your garden. You can also install buried metal fencing, concrete blocks, or bricks that are too heavy for the dog to move. Finally, you could use deterrents such as spray paint, hot pepper sprays, or loud noise makers to discourage digging.
