How to stop a dog from digging
Diagnose the problem.
If you can figure out why your dog is digging holes, your odds of changing the behavior will dramatically improve. Some digging is random and unable to be diagnosed, but usually there are discernible reasons for the behavior.
Dogs often dig holes for one (or more) of these five reasons: entertainment, physical comfort, attention-seeking, escape, or prey-seeking. Watch when, where, and how your dog digs, and you can probably determine why he digs.
