Another thought, if the dog is in good health (according to a veterinarian that has examined him recently). If he is a senior or has certain health issues, the following won’t apply.

He may not be getting enough exercise. I find that walking a dog for at last 1 hour a day can go a long way in calming them, less hyper, less barking.
Or, find an activity the dog is passionate about, a game of fetch, swimming, jogging with his owner….
