For a dog that chews when you are home, or chews out of boredom rather than panic, the work is straightforward and it has three parts.
First, management, because every successful chew makes the next one likelier. A dog that has learned that sofa cushions are excellent will keep testing that theory, so the dog does not have unsupervised access to the things it destroys while we change the habit. A pen, a closed door, or a dog that is simply in the room with you.
Second, something better to chew, available and obvious. Dogs need to chew; it is not optional and it is not naughty. The job is making the legal options genuinely more interesting than the furniture, which usually means food-stuffed toys rather than a dry plastic bone that has been on the floor untouched for a week.
Third, an honest look at the day. A young working-breed dog that gets a twenty-minute walk and eight hours alone is not misbehaving, it is under-occupied, and no amount of training substitutes for something to do. Scent games, training sessions, chew work and food puzzles all do more for this than extra running, which often produces a fitter dog with the same problem.
And do not tell a dog off for damage you find later. It cannot connect the two, so what it learns is that you are sometimes angry when you come home, which for a dog already worried about being left makes the real problem worse.
