Assuming you work 8 am to 5 pm, it may be because you have been gone for 56 hours in their timeframe!
Assuming the idea that one human year is seven dog years, every hour to us works out to 7 hours for a dog.
1 day for us, 24 hours of human time, is 7 days in dog time.
So 168 / 24 = 7 dog hours for every human hour.

The Rhen/Keeling Study

The average dog sleeps for about 12 to 14 hours per 24-hour cycle. That’s just the beginning, though. Puppies, who expend a lot of energy exploring and learning may need as much as 18 to 20 hours.
Can a dog be left alone for 8 hours?
For Adult dogs, Yes, it is generally, alright to leave your dogs for 8 – 9 hours, alone. Even in a Crate (dog kennel), 8 – 9 hours is usually alright. But for dogs under 2 years old, I would not advise leaving them in a crate longer than 6 hours if possible, or be prepared to clean the crate and bath a dog.
