I have a 4 year old pomeranian, in a family of 5.

4 of us will be going on vacation for roughly 12 days, and we are concerned about the pomeranian's tolerance to being alone.

The fifth person will be staying, but he due to work he has to be outside for half the day.

I am not really keen of leaving my dog with somebody else. Unless that's really necessary.

The fifth person says he will take her out every day, at least. Is it reasonable to leave my pomeranian alone for roughly 12 hours every day for 10+ days?
