I think you have to pick the solution you are most comfortable with so you won't have to worry. I know if I go away my first question is what about my dog. My husband would play with her but is not responsible on the diet and feeding at regular times or being responsible to keep with her training. My second solution is to board her but then she has little human interaction like she does at home - I work at home and am here all day except for one. The solution I always come up with is taking her with me. That way I don't worry about her and I know she is being taken care of. I realize you can't take her with you but it sounds like your parents are the best selection if they are home more and would stick to her schedule.
