I work full time and bring Duke to the office with me whenever possible. If I can't bring him to work with me, I drop him off at Nana and Papa's house (his grandparents) and they spoil him all day.
If my parents are on vacation and I can't bring Duke to work with me, then I just run home and check on him a few times a day. I'm fortunate enough to work about 10 minutes away from my home, so that makes checking on Duke a bit easier.
