It does depend very much on the dog. Mine sleeps a lot and he's fine for a period of hours, but then he gets walked either 2 or 3 times a day.
But a puppy is like a baby. If nothing else they need to eat more and wee more. You should tell the owner that he's barking a lot and sounds distressed. They might be able to get a dog walker in or something if they can't change their working hours to accomodate the dog more. If my neighbour told me that I wouldn't be upset - I'd be glad they brought it to my attention.
