NEED HELP - Digging Dog - What's Best Way To Stop?

Need some help getting our new Husky to stop digging. Our last Husky wasn't a 'digger' and neither is our Rhodesian Ridgeback.
We had to put down our prior Husky about six months ago and my wife missed her terribly. We adopted our current one a couple of months ago and all has been well until just recently when she (the Husky) must have discovered the joys of digging. Needless to say, the backyard flowers are disappearing at a rapid rate and my wife is getting very frustrated by it all.
So, how do we get both the Husky and the posies to happily coexist?
One of our friends suggested sprinkling cayenne pepper in the flower beds. Another said to put their poop in the holes they dig and fill them back in. What else you got that's worked for you
