My Dazzle is my little digging machine. Hubby built a sand pit in the far corner of our yard basically just for her. It's pretty adorable to watch her go to town in her sandbox. Alimony will occasionally join in, but Tipper never digs. He will occasionally plop his belly on Dazzle's freshly dug hill to enjoy the cool sand.
If you are concerned about digging, just don't leave the pup alone outside (I never do anyway), so you can keep an eye on him/her. Make sure he/she has plenty of exercise (walks, playtime, etc) so they are less likely to get bored and decide to start digging.
Or you can just give in like we did (because we thought it was cute) and make a digging pit. Fwiw, they never dig outside of the pit. They seem to understand that this is the acceptable location for such shenanigans. I think the fact that our soil is mostly clay and the play-sand is more enjoyable digging material helps.
