We are also a working couple and before my husbands new job, left Teddy alone for up to 8 hours. He has severe separation anxiety despite a lot of people saying that it was rare and could be worked around if it came up. It's a nightmare and not reversible and we're in doggy therapy with him at a local university. So, that's my situation which you can read up on via my various posts through the years regarding this but wish you luck whatever you decide
