Once you have ruled out a possible medical issue I would say maybe some stimulating games while you are gone could be helpful. Treat puzzles are fun or hiding treats or special toys around the house. Leaving on relaxing music can help ease the time away too. Little Kong toys can be a great option too, doggy daycare or a dog walker can be nice even if it is only available once or twice a week to break the monotony.
