Thanks for all the comforting understanding and words...
I can't wait to go home to check in on him.
I used to leave the TV on for him in the old apartment so he had some noise, I left my ipod at home for him today but I went out during my lunch and bought a small radio for him
I figured that hearing some noise will comfort him a little than complete silence then be startled by outside noises.
Yorkies are definitely different and it breaks my heart to have to leave him at home alone, our family is further away and everyone works so no one can really check on him during the day for me.
