I work part-time as a nanny (I have 8 years of experience) and attend graduate school in the evenings. However, I will have the entire summer off and plenty of extra time on my hands. It doesn't hurt to earn some extra income before I begin student teaching in the fall! I live with my boyfriend who is also willing to help if we provide in-home care. The most your dog will be left alone is 3-4 hours if we are out running errands, at the gym, etc. Fortunately, due to our flexible schedules, one of us is almost always home.
