Your dog has lots of reasons for wanting to dig. Digging is fun and relieves boredom. It also creates a cool place to lie in hot weather, and in some cases dogs dig to escape an enclosure. To prevent unwanted digging, don’t let your dog spend unsupervised time in the yard. Go outside and watch her play or, better yet, play with her. If you can’t supervise, bring her indoors.
If you don’t want to ban digging altogether, you can teach your dog that it isn’t digging you dislike, but digging everywhere. Choose one spot and designate it as her digging pit. Think of it as her sandbox. Let her watch you bury a couple of tasty chew toys. Then encourage her to dig in that spot to get them out. Your dog will learn that this is the best (and only) place to dig, because it’s where the buried treasure is and because you are there to help her choose the right spot.
Terriers dig? Of course they do! Terrier comes from the word terra, meaning earth. Terriers were born and bred to dig.
