I know exactly how you feel...it was so hard to leave my golden Otis at home by himself. It is now over a year later and I still go home to see him everyday at lunchtime. To be honest with you, I think he could care less - he's snoozing away everytime I open the door - but it makes me feel better so I continue to do it. Another option that he absolutely LOVES is doggie daycare. I used to take him a lot when he was younger to burn off all that puppy energy but now he goes once a week or once every 2 weeks just as a treat. If you do decide to pursue that option - be sure to look around for a reputable establishment. Good luck and try not to worry too much!!
