Yes, I feel so guilty. My husband and I both work full time - he is home alone from around 7:15 AM until 5:30 PM Monday - Friday. I actually have a dog walker Tuesday and Thursday (very expensive in CA, so only twice a week) t take him out to get some fresh air and a walk. That makes me less stressed out knowing someone has checked in on him.
It is getting easier since I he is passed the anxiety stage. He knows we will be back home!
